going live that's right as we float through the the universe here with
billions upon billions of galaxies with a
be with a
be we going Say howdy to all of our friends out there on
chat
for okay this looks
good
so David do you think that Bart Bach would be happy to know he's on the global star party I think he would be
thrilled I think he would be absolutely thrilled and I'm imagining sitting right next to me with his eyes glued to the
screen to see this I really think he would love this and I'm almost imagining he
is and he would say you know what where have I been the last 40 years I haven't done very much I've been a very lazy man
he'd probably say that too he's been resting you know yeah but
that's all right I think that the seeds of inspiration that he put out there though
are real still are very strong and I think that
uh you know I think he'd be very pleased to know that as
well okay well we've got some people already in chat here uh so um I see Mike
weasner saying howdy from Arizona and uh I was looking at Mike Mike weisner's uh
post uh that uh he did on Facebook today and you know just a really beautiful
image of his Observatory all kind of you know a a Time image you know with it all
lit up and red it looked cool so we got the space stuff here
hello everybody this is Rich Williams from Aster Florida 32102 USA
well here we
go astronomers spotted a black hole repeatedly munching on a sunlight star
thanks to NASA's Swift satellite when a star gets too close to
a black hole gravitational forces cause it to bulge and break apart into a
stream of gas This Is A tital disruption
event in some cases scientists see what they call repeating tidal
disruptions that's what's happening here with an outburst called Swift j230 the
sunlight star orbits a monster black hole every few weeks the star gets so
close that the black hole pulls off about three Earth masses of material but
the star survives astronomers saw in a distant Galaxy thanks to a new way to analyze
data from Swift's x-ray telescope they developed a new way of scanning the instrument's observations so that they
can quickly identify and study events like these after nearly two decades in space
Swift is still learning new tricks and teaching us new things about our

hello everyone this is Scott Roberts from explore scientific and the explore Alliance and I'm very happy to uh
introduce you to the 136th Global Star Party the size of the Universe um I had the Good Fortune to
run across a couple of uh of fulllength lectures from the legendary astronomer J
Bach him and his wife Priscilla uh had written a book about the Milky Way um
and um I actually sold uh his book uh at a uh telescope shop called opt back in
the 80s and um I loved the uh the the way that he wrote about the Milky Way
and uh um I think I actually even carried posters there were these long
posters that showed uh the Milky Way taken from both the northern and southern hemisphere and um anyways uh
these uh lectures uh were recorded uh by
WGBH Boston the same guys who do the science program Nova uh this is back in
1957 and take note that um the the content of the presentation from Bart
Bach had information that was then state-of-the-art for um for the uh the
distance Scale of the Universe and such but I think what you'll find is that his
presentation style uh the way that he uh educates people uh is something that um
you know you would have to see him do uh to really understand how amazing it is
um also uh I have the Good Fortune we have the Good Fortune to know David Levy
and if you've been keeping up with global star party uh you've you've gotten to know David Levy as well uh but
David knew bark Bach and uh and Priscilla um personally and uh uh so we
have a connection and so I'm gonna let I'm gonna turn this over to David uh who
can introduce uh Bart Bach like none no one other people can because U David also
wrote the biography for Bart Bach so David thank you for coming on to the 136
Global star party and um making this special introduction well thank you and today
I'm going to combine my poetical my poetical quote of the
week with um my introduction of Bart Buck it was kind of an interesting thing
I was I just relocated to Tucson Arizona I bought a house on carry Street a very
small house it's not the house that I'm living in now but uh a few weeks later
my friend Peter Jedi came by for a visit and we had a good time and looking up at
the night sky and doing observing and I remember I remember in
fact one night we were observing the sky and a cloud a little serero cumulus
cloud appeared in the Northwest and start slowly crossed the sky and then
disappeared in the Southeast and I looked at it and I said Peter you've just seen the Arizona monsoon
season and he got a good laugh out of that but as I was driving him to the airport he's sitting in the car next to
me and he said David your task should you choose to accept it is this I want you to
interview Bart pck and uh
uh because I'd like to write an article about him and I want you to interview him for me because I wasn't able to do
it get a chance to do that and I thought Peter I can't interview Bart boach he's
one of the most famous astronomers in the world and I just can't call him up he
said sure you can and so I was really a little annoyed at Peter at the time but
as I let him off at the airport I resolved that I was going to call barck I Pi up the phone called his number and
he answered the phone this is B he said I am fresh out of the shower and
I'm dripping wet I have a beautiful girl in the Next Room who is also dripping
wet so be quick and I said Dr Bach this is David leaveing calling be quick be
quick and and I said I would like to interview you but uh this obviously not
a good time how about if I called you tomorrow be quick be quick I said Bart Dr Bach I'm GNA call you tomorrow and he
said no no no no you're talking that is a good time let's set up a time how about tomorrow at 3:30 you come to my
house and you can interview me the next day was really shaken by that first call
but I arrived at his place the next day at I think it was more like
4:00 and uh he let me in and uh I had
five questions that I wanted to ask him that I had written down and he was sitting on on his couch
and I was sitting in a chair and I said Dr Bach when you were director of
the uh Australian the astronomy department at the Australian National
University uh you wrote a book called the astronomer's universe and the first
five words in that book were astronomy is on the Move Dr Bach how would you explain those
five words now and how would you explain them 20 years after you wrote them I never got
to ask another question he started answering painting a wide picture of the
origin of the universe of the Milky Way after an hour I had to excuse myself to
get another tape from the car which I ran out and got got in and he continued
answering the question for about two hours and uh I was I've never forgotten
that my first meeting we eventually got to be very very good friends and when
Peter arrived for another visit later that year I was able to introduce Peter
to barbach and by then we were pretty darn good friends and
uh uh we the friendship was based on
science but it wasn't limited to science he uh we talked
about girlfriends and things like that which was pretty odd because Bart uh
when he was married to Priscilla was very conservative he did not believe any
of his students had the right to have extramarital Affairs and when he found one who did have an extra marital
Affairs he shunn that man and uh you know so it was really pretty odd when
his friends found out that after Priscilla died in
1975 November the 5th 1975 that he actually had a another
relationship with a woman who is also married to someone else at the time and
uh he really fell in love with this woman I think her name was Jackie and uh I remember one day years
into our friendship he called me and he said oh Bach is not happy today because
Jackie has canceled on a visit to him and he was crying he was sitting there
in the phone crying his head off I talked with him for a while but then I called a friend of
his Elizabeth naio and uh suggested that she might
want to visit with him which she did and she spent the rest of the afternoon with
her friend Bart Buck uh it was really really
interesting and really exciting how he was able to remember the marriage that
he had with Priscilla and the beauty of that relationship and how he told me about
the uh her last days and they went to the opening of the flandro planetarium
in 1975 November the uh I think it was November the 4th
1975 and they went in and they got there very early and they went to the back where where they had set up a room
called the Galaxy room and uh they were looking at the beautiful transparencies
of the Milky Way and all the other things that they can see and uh Priscilla stopped and he said
she said at the picture of the Ocarina nebula she just stopped and froze and
said Bart you know that I'm going to die soon
and bartard argue with her said oh no no you're doing fine and just shut up and
listen you know I'm going to die soon I'm telling you right now that here is
where I want to be in the ekarina nebula and uh this is where I want to be when I
am gone you can always find me in the at karinaa nebula four days later Priscilla
passed away and one of the few mistakes that Scotty has ever said regarding me
when he said that I knew Priscilla I knew Priscilla only through Bart it was
just a few years after she had passed that I was able to get to know Bart but I had never personally known Priscilla B
had always told me that Priscilla would have loved to meet me but she never had that chance I have here with me two
books one of them is the first edition of Bart and brazilla box the Milky Way
that they wrote together he uh he actually went through
five editions of that book the fifth one that he had to revise without her and
the other book I want to show you is the The Man Who Sold the Milky Way when that
I decided to write a biography of him and um and this is a book that is I
believe I'm not sure it's still in print it probably is by the University of
Arizona press it is my biography of barbach and it is from this book that
I'm going to quote today's poem which is not really a poem it's more a more a
verse um pros and
um I wrote it when I wrote the biography of Bart
boach and I'd like to share that with you now and then pass the Baton back to
Scott who will begin this lecture that we're all waiting for when we all think
about the um the size of the universe we usually think of Edwin Hubble
I don't think of Edwin Hubble I think of Bart boach and I remember being at the cemetery last week
arranging the um arranging the unveiling of the tombstone for
Wendy that'll take place on the 17th of December at 11:30 at the
cemetery but anyway as I'm about to leave the cemetery Scotty called and he told me that he had discovered this
fabulous lecture by Bart buck and he said maybe we should
do it on Bart's birthday which will be April the 28th
1906 and uh will Mark the 40th anniversary of his death which was on a
in August of 1983 anyway here we are with the prep the
opening to the preface of my book The Man Who Sold the Milky Way and it goes
like this in the beginning there was no B and the
Milky Way was without form and void but darkness no longer is upon the face of
the deep for Bart J Bach has helped explain our galaxy to us and on that
note I give everything back to Scotty thank you Scott for letting me do this thank you so much David um uh I um
before I start this uh this uh uh video segment uh you know I want to give
recognition that this was U produced by WGBH uh in Boston um I believe that uh
Bart Bach was uh doing these lectures live because the the recording is a k is
a kinoscope and the way a kinoscope works is you have um you have a a motion
picture camera aimed at a television and then you're you're recording what's on
the television uh the resulting recording uh that I saw was very little
contrast there was quite a bit of uh audio uh Distortion in the background
some you know Rumble and his that you might expect uh when you see an old movie this was uh filmed in
1957 so uh he would be giving the lecture I think live and then the
cameras right there aimed at the television Monitor and um uh so uh um
you know but I I really want to thank um u u uh Paul Newton who works here at
explor scientific for um making corrections to the audio the audio might
be it might be better than what it was originally um uh the the uh the visual
video part of it uh probably not as good as actually seeing it done live but uh certainly better I think
than um than what they got from a television screen so um but uh anyways
uh through the through Modern software and the um you know the the fact that
the uh video is now Beyond copyright um I think it's it's wonderful that it's
out there for the public to see and uh David I would really want to thank you for giving this presentation because it
brings life to uh you know an otherwise kind of um not lifeless but uh kind of
uh how would I put that you know kind of a stoic um uh T type of introduction so
but uh thank you thank you Scotty I'm really looking forward to this I'm sitting here my emotions are all in a
turmoil as I remember somebody that I really loved and really respected and
admired yeah so here we go
um Bart Bach uh and his lecture the size of the
universe my task tonight is to tell you quite a bit about the arrangement of our
universe the arrangements of the stars of the galaxies of the planets of the
Sun how they all are together in the universe what their distances are and how they are related to each other this
Photograph that we have here is probably as good a one to start on as any because
on this Photograph we see dots and every dot is a star and these star dots are
each of them represent sons all of them Sons very much like our own son some are
fainter some a little brighter but all suns in their own right these little
places that we see here these smudges they are galaxies they are large star
systems well beyond our own star system or our own Milky Way system and these
star systems themselves are at very great distances from us we shall find
that these can be observed to distances as far away as 2,000 million light years
a really very great distance in space the stars are somewhat nearer by but
before we turn to the Stars let us turn first to the nearest neighbors that we have let us turn to our own solar system
the plan that I have to start out with our own solar system and gradually move
out from the Sun to the planets from the planets out to the nearest stars from
the nearest stars in our own star system our own Milky Way system to the farest regions and Beyond and I hope that to
give you an idea as to how these are arranged now the first photograph that I
have here is of a very familiar and basically not very interesting object
the moon all of you have seen the moon you know that the companion satellite to
our own Earth it is not very far away from our Earth its distance is only a
little more than 200,000 miles which means that at the speed of light 186,000
m a second a light ray goes from the Earth to the Moon in a little over one
second many of you will probably remember how about 10 years ago for the
first time a radar beam was bounced off the surface of the Moon that radar beam
signal sent from the earth spr towards the moon returned by the moon to the
earth took a little over 2 second to complete the whole trip what we say is
the distance to the Moon is about two light seconds for a little over that but
now let us really come to the important body in our solar system which is the
sun itself here is a photograph of the sun with some of the familiar sunspots
shown in one of two position the sun is a star it happens to be to us the most
interesting star because we happen to be very close to it and our Earth is one of
the planets around our own Sun the distance to the Sun is 93 million miles
now you might say here he gets busy and throws large figures around and tells us
about distances that are so large that we cannot imagine them let us just try a moment to imagine what 93 million miles
is like well many of you must have had a car that has run 93,000 miles my own car
has gone at the present time more than 86,000 so I know just how far it is to go about 86,000 miles
and I can imagine very well how far 93,000 m is well if you imagine a
parking lot there 1,000 Park old cars all like mine more or less these
thousand cars will have travel a, time 93,000 miles which would be 93 million
miles I hope that that will give you an idea that the distance is great but not a distance that we cannot imagine now if
I continue to talk all the time in terms of distances in Miles the figures would
become so large and so unwieldy that they wouldn't make sense for that reason
we measure in astronomy our distances more in terms of the time that it takes
for a light rate to cover a given distance light moving at a rate of
186,000 m a second travels the distance well that is about 7 to 8 times around
the Earth in 1 second travels the distance to the Moon in a little over 1 second it takes 8 minutes to go to the
sun we say therefore that the distance to the Sun that 93 million miles is a
distance of8 light minutes since it will take a light Ray 8 minutes to travel
that particular distance now we ask what other distances are there in the solar system let us look at one of the other
objects in the system and return to the biggest and best of all the planets that we have the planet Jupiter many of you
have probably seen Jupiter you probably have seen the belted structure which comes in a cold atmosphere of ammonia
and of methane these little black spots by the way are
shadows thrown by the satellites of Jupiter on the surface of the atmosphere
this planet Jupiter is at a distance five times as great as the Earth from
our sun therefore 5 time 93 million miles is the distance from the planet
Jupiter to our sun in terms of light minutes 5 * 8 is 40 minutes it would
take a light R about 40 minutes to go from the earth from the sun to Jupiter
if you move out there are other planets for example there is the famous planet satn with its beautiful ring structure
it's a little farther out let us not worri too much about the details of the figures but we can say that the solar
system with all its planets is contained roughly Within a distance of about 40 of
these astronomical units 40 * 93 million miles distance from the Sun that system
has some very distant outlying members the Comets are probably the ones that go
farthest out there you see a very fine example of one of these comets the Comets there are the objects that go
farthest out in our solar system and therefore we go up to distances of about
50 times this 93 million miles to complete this let us look at a diagram
that gives you some idea about how this Arrangement really works here we'll see
Neptune one of the alter planets Pluto lies Beyond it Neptune up here Uranus
down here then we move in from Uranus to the planet Saturn to Jupiter to Mars and
the Earth this distance from the Sun Point here to there the next one that is
about 93 million miles at the speed of light therefore we can
say that the dimensions of the solar system cutting once across the entire system are of the order of about say 10
light hours in other words if you were to start from the earth and right after
breakfast and go out and want to visit all the planets and do so at the speed of light it would just take you a full
long day's work and you would be home in time for a late supper in other words
the dimensions of our solar system are measured in terms of light hours let us
just note a few of these things on the
Blackboard the first one that I would like to record here is that the distance
from the Earth to the
sub is 93 million that must mean we need six Zer with that 93 million
miles that is equivalent to 8 light
minutes the second one that's the dimensions of the solar
system so we go through the solar system from one end to the
other in about say 12 light hours so
moving at the speed of light 12 hours to go through the solar system well that
gives us our first basis for discussion we know how far it is now from the Earth
to the Sun what the dimensions are of our solar system and now we turn to the
system of the Stars in this very fine photograph that I have here you will see a section of our Milky
Way at happens to be the section of the northern Cross of signs those of you who
know your stars May notice dap up here alberio the end of the Cross is just off
the photograph here we have the cross bar in this Photograph you see a great
many dots and you remember from the earlier one that every one of the these dots is a star that every Star again is
a sun and that these Sun stars are in many cases brighter than our own sun in
other cases intrinsically fter in other words our sun is a pretty average source
of a star when we ask about distances to the star Dots here they will come out
something of the order not of light minutes but they're measured in terms of light years let me first of all remind
you that whereas the dimension of the solar system is measured in terms of
light hours 12 we wrote on the Blackboard that the distance to the nearest star so from our sun and the
planetary system to the next star is four light years the first thing that we
notice about the universe is that it is a very big and empty place here we are
with our solar system about 12 light hours you got to travel at the speed of
light for 4 years years to reach the nearest star when you take an average
star dot here in this Photograph the distance of that star is not four light
years but more likely 4,000 light years we see therefore that there is a
terrific depth to the space that we have let us look at this Photograph a little
further for from it you can begin to see some of the basic features of the
structure of our Milky Way system as we come from one corner of the photograph
and move slowly closer and closer towards the center become to more and
more star Rich regions you will find that generally everywhere in the sky if
you look at the band of the Milky Way in the sky that can see be seen very beautifully at certain times of the year
then you will find that the band of the Milky Way is a region of high star concentration there are more stars as
you come from a distance and go to C the Milky Way in the Milky Way than at some distance away from it in other words it
looks as though the Milky Way band is a real band of star concentration we find
that the stars in the Milky Way are at many different sort of distances some are nearer some farther away in other
words the Milky Way has great depth our sun is a star near the central plane of
a large system of stars known as The Milky Way system a highly flattened system as we can see go at right angles
to it very few stars in the plane many stars indeed here we have a section in
the Milky Way let me draw attention to two other features one of them this
little nebula called the North American Nea for obvious reasons here you can see
almost the F Canal the Gulf of Mexico cape card is missing and here is the coast of California well this nebula is
made out of gas it is gas that floats in between the stars because for every
three gr that we have in the region around the Sun in terms of all sort of matter two GRS are squeezed in the stars
in the Sun the other gram is left to float free as gas and Cosmic dust in
between the Stars this dust is shown for example here in the Gulf of Mexico or the Pacific Ocean or the Atlantic tiny
little icles that float in between the stars now let us have a good look at the
Milky Way by itself the next one shows you the outline of our no way chart remember that we had
this region up here in our photograph we know already that these clouds are not really clouds but they are really star
dots effects of a great many stars coming close together in the Milky Way
we know that the concentration of stars increases as we go from the outside towards the central bed we notice
something else some parts are exceedingly brilliant like this one up here near Scorpio and
Sagittarius another part the part that we see from our latitudes in Winter near
here taus and Orion that part is very much thinner what is the
case when we look at this Photograph we see here certain pirs are very bright
and Brilliant like this P that we see in the summer Scorpio Sagittarius other
Pirates are very much weaker like the PIR in to the and in Orion that we see
in our winter Milky Way why is that simply because we are in the central
plane of the system but pretty far away from the center itself let us have a
look at one more of these gas clouds of the Milky Way because we shall find that
they clouds like this up here they really give General outline of the
structure of our system and especially delineate where the spiral features are in our system
the Dots here Suns again the gas shown as white beautiful clouds the little
things like this little black hole here the keyhole Nable we call this they are
produced by The Cosmic dust the Milky Way system if you could see it from the outside it would probably look something
like this system up here we were probably living in a point in this large
star system like the one shown here by The Black Arrow our point is roughly
about 27,000 light years away from the center the diameter of the system
approximately 100,000 light years a few years ago Mrs buck and I drew a diagram
of our Milky Way system and it still serves pretty well to show you what dimensions are involved the only thing
that we need to do today is whereas a few years ago we thought this was a scale of 100,000 light years it is now
more likely that this represents 80,000 light years but if you take that one
correction this gives a good picture looking down on the Milky Way the sun here the center of the Milky Way here a
distance of 27,000 light years 100,000 light years roughly from one end to the
other seeing sidewise there you have the general picture of our Milky Way system
one final point the Milky Way moves around rotates around the center from
here to there 27,000 light years we move with a speed of 140 m per second that
means while I say 1 23 the Sun the Earth and everything Vis it has gone 140 miles
how long does it take us to go once around just one complete circuit while the next gra will show it to you you
will see that it will take you quite a while to complete one circuit 200
million years so one Galactic Revolution takes place in 200 million years we call
that often one cosmic year this will give you an idea of the tremendous size
of our Milky Way system so much for the Milky Way let us write a few of the facts on the Blackboard first of all
that the diameter of the Milky Way
system I write it as MW system is about
100,000 light years let us write up the next thing the
distance sun to [Music]
Center is 27,000 light
years and the distance to the nearest star distance sun to near near
star is four light years there we have sort of the effects of life as they
affect the stars and as they affect the Milky Way system and now in the final
few minutes let us get out into the universe of galaxies each Galaxy is
probably in spiral galaxy just like our own system is like the one that I've
shown you already to give you an idea of it let this be a typical Milky Way
system 100,000 light years from here to there are sun 27,000 light years from
the center to give you an idea of the arrangement let us just take these Milky Way systems and suppose that all of them
had the same dimensions as our own some are in fact a little smaller but that is
beside the point the important question to realize is that these systems are roughly about 1 million like years away
which in other words means this that if we want to build up the universe take a series of these discs make each of them
a 100,000 light years across put them a million light years apart and then throw them out in space like we're doing here
there they go be sure they stay a million light years apart keep it up for
something of the order of about 2,000 million light years 2,000 million light
years and you have the universeal galaxies now there is the universe let us have a look at it and see some of
these things in a little more detail here is one of these galaxies much like our own probably spiral structure gas
dust all the various things in it shown rather nicely in a photograph with the 200 in telescope of Mount Palomar we
show you another one that we see Ed on rather than face AR and there you can
see again the central balls that we had are our sun would be in a position like
this this black belt in the middle is produced by The Cosmic dust that Shields
off the light from the more remote objects let us look still at some others then we'll find out for example that one
of the most famous of all is the famous Andromeda galaxy you can see it faintly
in the sky as a faint star sometimes with a little blur when you see it in a photograph you see the spiral structure
coming out in it you can actually photograph with the big telescopes the individual stars in a galaxy or Milky
Way system of that sort this one is probably a reality a little bit bigger
than the one that we've had already let us look now at some that have a slightly different structure like this one up
here where we come into one that is irregular in shape this is a satellite
Galaxy to our own Milky Way system the large maganic Cloud but you see there are the common components of gas stars
and dust that are ever present but let us finally say how far can we go out
here is one photograph of a really distant group here we're coming in terms of distances of 10 million 30 million
100 million life years and bigger we're really moving out in space finally when
we come to the real distant ones we will find that we come into distances that
are still far greater we find for example that there are some that receive
from us with terrific speeds at very very fast rates of the order of about
say this one here 20,000 km/ second that is about 14,000 miles some have been
measured with speeds five times as big this dist has a distance of about 100
million light years the greatest distances for which this expansion effect has been measured run as high as
about 500 million light years we go beyond that the faintest galaxies that
we can photograph are probably 2,000 million like years away well in the last
minute let us return right to the Blackboard and see where we are again and here we have our picture I'm
starting now we might Almost Say from the bottom up remember that the galaxies
measure about 100,000 light years across some a little smaller some a little
bigger let us remember too that the nearest star is even still four light
years away from us remember that these galaxies at these dimensions are about
10 times as far apart as their diameters that we go up to distances as great as
200 2,000 million light years remember too that in these light years that light
goes around the Earth 7 to eight times in one second 8 minutes to the sun 12
hours to the solar system four years the distance to the nearest star 100,000
Lightyear per Galaxy and there we have about the story of our universe as far
as dimensions are concerned you so uh I hope you enjoyed that um uh
David what do you uh what was your take on this particular
lecture uh yeah that that was let's see if I can
mute myself here yeah you're unmuted okay okay you can hear me I felt
I felt as though Bart had come back from heaven and was sitting right next to me
he was listening to himself I cannot give a lecture as good as that I mean my mind would
wander but listening to what the way the the feeling and the emotion with
which he gave that presentation is beyond anything I could imagine myself giving and it was wonderful I was
honored beyond anything beyond any way that you could say to be sitting in
imagining Bart sitting next to me listening to himself talking about the
size of the universe and using our own Milky Way galaxy as a um as a
feeling as a centerpost to to leap off and
discuss the uh origin of the universe This is 40 years later it's
actually 60 years after his lecture or more and it is almost impossible to
imagine how our understanding of the size of the universe has gravitated has
moved so far away from the way we saw it in 1957 and yet the feeling is the same the
emotion is is the same as it was then it was just such an honor to imagine bar
sitting next to me un watching himself give such a wonderful wonderful presentation and thank you back to you
Scotty thank you very much that's great okay all right well um I am uh I
think I'm gonna be like a lot of you out there and I'm going to be rewatching this video uh as I might have mentioned
I did kind of watch it from a technical standpoint after we did the restoration work and all the rest of it um I can um
for those of you that might want to show this to an astronomy club or whatever uh
we're real happy to share the uh actual file uh that we
restored um but there are a couple other places that you can find this video uh
one of them is at archive.org where I did the original download from from uh
but uh I think there's a couple of universities also that have downloaded the video and show it on their
University website so um but that that's fantastic uh and
I'm gonna bring David Iker on okay David um your talk is next your presentation's
next but uh uh what was your thought about this particular presentation well
I thought it was fantastic and and I only got to know Bart at for the last couple years of his life uh there and L
largely at the Texas Star Party in in Tucson a little bit and it was through David that I got to know him um and I
think you were working on or or just had finished working on his biography in those couple of years this would have
been 1982 and three I think mostly um David so so you know that that
it brings back a flood of memories of what this guy was like and and you know this in 1957 this was a long time before
I I knew him but but the same quirks and sort of you know home you know
friendliness and you know deep caring about sharing the information about the
cosmos with others comes through in this talk that's the way I remember him just
the three of us talking David when you know when we were at the Texas Star Party there and so on um you know is
very much you know it it's like being Revisited as you said by by him and I thought it was
interesting now we know you know that the Universe the diameter of the universe is 93 billion light years and
maybe more depending on Dark Energy you know it could actually be infinite you know so it's a lot larger than we would
have suspected in 1957 but the basic those simple basic numbers he was talking about there are
still legitimate what he mentioned there those numbers now still and I thought it
was really interesting uh you could almost hear Bart you know one of his favorite things I remember him saying
and David I know you know this better than me you know all the good stuff's in the southern hemisphere he used to like
to say you know which is not much of an exaggeration you know and of course he spent a great deal of time in Australia
with his Observatory directorships but I thought it was very interesting that he showed when he was talking about the
Milky Ways may be similar to a Galaxy like this and he showed
M83 and a bar spiral and we knew that the Milky Way was a b spiral that was a
surprising confirmation in 2008 yeah was that struck me as sort of
a weird coincidence hear this is in 1957 and he's showing a Bard spiral
talking about this back you know deep in the days when we thought the Milky Way was another SB spiral like the Andromeda
galaxy that was a little spooky I thought that he showed M83 which is very
much the kind of Galaxy that we turned out to be so so that that really kind of struck
me as amazing you know but his Insight is really I think remarkable so yeah and
and of course he and Priscilla get you know the book that David showed a copy
of the book uh it's a proud possession I have the fifth edition signed by Bart
Bart inscribed by Bart but that was in its day up through the early 1980s and
you know that was the book on the Milky Way bar nut that's they were the
definitive experts on our galaxy and period end of story you know and and so
it's really you're hearing the greatest mind on the subject of the
Galaxy talking about this Cosmic distance scale in this lecture I mean you know he was at the very top and so
it it's just amazing to see I had never seen that before David that was that was
really so interesting to hear you say that one of the books that I have in my own library that a lot of you may have
in your libraries is The Golden Book of astronomy and it's one of my favorite
books that I had since a child and if you open that book you get to the forward the forward was written by Bart
Bach when he was at the Australian National University and uh I think when I read
that as a child was when I first got introduced to the magic of Bart J
Bach and of course David's biography is the definitive bio you know that's still
a very important book David your biography of bar absolutely that
summarizes his whole career yeah so I created a um a mini biography of Bart
Bach and uh at the bottom of that page and I I put the link already in chat uh
you can find a link to uh Levy's uh biography as well as the Milky Way book
which is still available so um so it's it's as you know if you're into amateur
astronomy or professional astronomy this is probably a book you should have in your library
so one of I would that I would like to um to end this particular section with
before we go to David's lecture sure is the dedication of uh of The Man Who Sold
the Milky Way I dedicated that book to my mother Edith pet Levy who encouraged
me during this Project's difficult beginnings and whose patience and love for my father during his last years
helped me to understand what BART and briscilla must have lived through because just as Bart was just as Bart
was taking care of Priscilla during her last days my mom was taking care of my dad
during his last days and uh and that was such an incredible comparison that I
felt during the time I was writing that biography I just want to share that with
you Sensational David thank you for thanks for sharing that and what what
memories are tied up in those days back then that we had you know getting to know him he was just you know there you
can say this about a relatively limited number of people somebody who comes into a room and is just Larger than Life you
know he was that kind of a guy yeah yeah I I'm glad that we were able
to I'm glad first off I'm I'm really glad that uh that these video these uh
these films were made um and um you know I know that just from reading the
biography of Bart boach that um that he and Priscilla really leveraged uh media
during this time um uh when you know frankly it was very expensive to do so
you know um so uh I asked um I asked
David Levy um you know what his opinion was as far as uh art box stature amongst
uh astronomers at that time uh or even at this time and uh you know and I I'm
I'm mentioning luminaries like Carl Sean and stuff how David what what is your
take on uh uh Bart boach stature in the
world of Astronomy Today well I think it it is probably it
has probably diminished somewhat over the years because uh unlike Carl San who uh who
really was a astop popularizer first and a scientist second Bart was a scientist
first and an astropop poiz second it was very difficult to separate him his
science from his public relations but I think that um that he
was there someone very very special as I was watching this wonderful lecture I
was taking notes into my observing log this is session number
23, 967 which was today's observing session
of the night sky of the Sun and uh and I'm in my observing log I'm
taking notes from Bart's lecture and I think it's so very special that that the
um that the lecture which we saw today will forever be a part of observing
session 23967 wonderful wonderful thank you
David um okay uh I am um I am ready to turn
this over to you uh Mr ier and uh you're taking us to um a uh one of the Exotic
uh deep Sky objects and it is pism Marino one is that right I might
pronounce if people know this well and they've observed it a lot I'm gonna get
up and walk out of the room okay because I thought you know last week last time
we had NGC 6946 a pretty big exciting object this
is truly a an obscure object I think this time it's an open St cluster and
it's in we're still in the northern sky working our way Southward toward that good stuff of Dr Bach uh but this is an
obscure cluster that is involved with an obscure nebula and uh there's not a lot
that's known about this one so it'll be interesting to show some images of it and and talk a little bit about it all
right we'll take it away man thanks Scott so I will share my screen and I
will see if I can get Centaur a one of favorite object of Barts I think it's
fair to say um and oh dear um this is on the top of the screen
now oh my gosh now it's covering up where I start the slideshow here here we
go okay sorry about this it's all right all right I outwitted it the bar
moved and was blocking me there so anyway yeah Bart I know that Bart loved santur a um one of those great southern
hemisphere galaxies but we're not talking about it now as Scott said we
are talking about now it doesn't want to advance either my golly this computer is
not cooperating so how many of you let's see a show of hands here or in the
comments section how many of you are familiar with pism Mareno
1 um I wasn't before I came over this to these things you know so that was as of
yesterday this is getting to be a little weird as they say now it's some of those old
movies um so anyway this is a high latitude open cluster it's in
cus it was discovered by the team of an Armenian Mexican astronomer a woman
named Paris pism and the Mexican astronomer Marco Moreno um uh and and again I'm blocking
part of my text here forgive me Marco Marino Corral there we go okay um and
this is getting to be a little weird because it was not known you know until the
1960s not recognized as a cluster little data has really been reported if you go
to simbad you know or Ned or anything else there's practically nobody has
studied this cluster so there's more astronomer to astronomy to do in the future astronomers have not yet uh lost
their job security in every respect at least it's about nine arc minutes
across um but there's not a lot that's known about it out there the faint uh
sharpless nebula 2-140 is involved in this cluster and presumably physically involved because
the cluster is is you know believed to be a creating from it it's about 2900
light years away and the the nebula's bright Rim is
caused by a main sequence uh HD star and it's ionizing to create this Rim a Bach
globule and of course Bach globules are very famous very tiny uh Bart in his
lecture mentioned these pockets of dust in signis and elsewhere and Bach globules are very small uh concentrated
areas of cosmic dust uh that are accreting down to form protostars that
he became one of the several things he became very famous for this area is part of the sephus
bubble which is a big shell of gas and dust and it's associated with a big uh
group loose group of stars the sephus ob2 association which is in our neck of
the woods in the Milky Way so here's the region of pism Mareno
one and I don't think you can see my arrow here can you um probably not that's just just for me but you can see
over left and a little above Center is pism Mareno 1 and uh the sharpless 2140
which is the emission nebula that's associated with it there's a double star
stru 2896 in there as well and it's a fairly Rich area of cus you know this is
up above signis and still in a rich area of the Milky Way you can see how many bright stars are on this chart a very
small section of a few degrees in each Dimension here this is again courtesy of Ron stoan
and his great Atlas here uh and this is the sky survey image
when I started to try to find images of pism Moreno one there aren't that many
good ones out there so I knew I was finally getting to something that was obscure but this is a digital uh Sky
survey image and you can see the cluster here you might even think that it has a little bit of a bent coat hanger shape
here and you can see the Wisp of nebulosity there from steuart sharpless in his catalog that came
later and this is a really nice image from astrobin the Astro photography site
where lots of imagers post their stuff Astro fin whoever he or she may be uh
produced this image and stuck it on astrobin here and this is really great I mean you can see in the center just
right of Center is that kind of bright lip of Mission nebulosity this is all
gas It's associated with the sharpless object and then the cluster is kind of the bright group of stars over much of
the middle of this uh um part of the image in front of the dark nebulosity
and in front to the right there all the the the bright stars that are uh just to
the right of that lip of of emission nebulosity there so this is a weird one if you want
to go out and look at the northern sky here's another image of amateur image by Daniel Whit andorf in Germany of the
area showing the cluster in the group and you know if you think you've run out of things to look at with Scott's
telescopes here's one you may not have seen which is a kind of an interesting area here's yet another one uh image of
of the uh area as well by Felix Milo um which shows it very very nicely
a little bit wider field and you can see that there are a whole lot of stars in
this small section of the seus Milky Way so this is a weird object that I don't
think I've ever seen visually and is maybe worth going out and taking a peek at and in a dark sky presumably with an
eight or a 10 inch scope the nebula would be faintly visible as
well we're getting to the very end and you're going to say thank God the very I
won't mention this again here probably but this is the end of our 50th anniversary year of astronomy magazine
here and we have a bunch of stuff including some Recollections of Jim Lovel and Apollo 8 here the guide to the
night sky the annual stuff I had to give a talk I have to give a talk that's coming up early next year about
astronomy and the Civil War and so I figured well you know I'm getting a talk ready I might as well do a story in the
magazine about it so that's in there as well and I'll tell the story sometime uh of Cl in up in the if you ever get a
chance to visit the old Naval Observatory in Washington not at the
vice president's house but the old Naval Observatory which is at a site that's a
couple blocks north of what's now the Lincoln Memorial site you can climb up into the telescope the refractor there
through a wooden uh entryway and a wooden ladder that's the same ladder
that Abraham Lincoln used to climb up into uh in an unannounced visit
David I think we talked about this many years ago from time to time and dropped
in on uh a young astronomer um who would
uh what was it this was in 1863 a few weeks after the Battle of Gettysburg so
14 years later this astronomer that President Lincoln and his private secretary John Hay dropped in on would
discover the two moons of Mars so there's some astronomical history there written up and you too can make
arrangements if you want to and go visit the old Naval Observatory and climb right up that same ladder that Abraham
Lincoln used also uh both Scott Roberts and the
distinguished David Levy will be there and speaking and having a good time uh
this coming spring uh at staris number seven in Slovakia and Braava which is
fabulous place I was there few weeks ago to announce the festival um will it's a
hop skip and a jump from Vienna so you can get to VI Austria very easily and
just drive right over to Bros laava and it's going to be a festival that is full of surprises that will be mindblowing as
it always is with many astronaut explorers Nobel Prize winners rock
musicians and lots and lots of other stuff going on at stara so we hope that we'll you'll join us there just a few
scant weeks about five or six weeks after the big Eclipse that's coming this
spring as well that will be a big highlight for all of us so that's all I
have I will end the show and I will stop sharing my screen and Scott thank you
for allowing me to join you again and that is a truly obscure object this time
if you go out and and anybody talks next week about seeing a piss Marino W I will
be duly impressed that's right that's right so
um John Ray said he said his H stellarium software found it in about
half a second so nice nice all right there you go so we challenge everyone to
go out there and see this uh uh obscure but I'm sure beautiful object you know
and the astrop photograph of it is pretty amazing it is a pretty starf and you know signis has so much great stuff
of all types in it you know even galaxies but stuff in the plain closer
to the plane of the Milky Way there of of of Galactic deep Sky Wonders that we
don't think of cus that much but there's a lot of good stuff there and that is a beautiful Starfield with the nebula
there as well great thank you so much David thank you Scott thank you okay
well uh we are going to leave the US a and uh fly through the miracle of the
internet all the way to Nepal uh where we will uh meet up with DT gam now many
of you who are regulars of watching the global star party or remember deept uh
she came on early into the global Star Party program uh and she she has given
several talks uh uh on uh different aspects of the universe
um but uh she also many times will add uh poetry that uh that she has done uh
which actually inspired me to write a little bit of poetry myself so uh now I don't have anything for this particular
Global star party but uh um DT uh thank you for coming on to uh Global star
party again uh I also want to point out that she has been uh inducted into the
explore Alliance ambassador program uh you're in good company uh with many
other luminaries uh in the field but um I can tell that you're kind of into this
for the Long Haul I think that you're that you're you so far have done this for your Outreach work for several years
sometimes I see young people do it for a couple of years and then they kind of fade off and stuff but I think you're
still going strong and uh we're really happy to have you on global star party
and making this a part of your outreach program hello Scott and everyone uh so
it's me DP goam from Nepal uh yeah I just uh join my undergraduate uh
University uh here in Nepal that is K University taking major of bachelor in
like taking major electrical and electronics engineering uh so uh I had a onee gap uh
between high school and University uh so I enjoyed it I learn it uh through
the astronomy and I completely given my time to the astronomy so let's go
through the I would like to share my
screen uh so uh here in Nepal I'm okay sorry I'm recently working with
Nepal Astronomical Society naso uh and I have given my full time here uh for this
one year and I had a a little bit of more Gap in global star party
too uh so there was a different programs I was engaged in and the one of these
astronomy for Community empowerment in Nepal uh this is the one program uh which has the motor
to uh teach the student uh Mentor them and make them a mentor to go to the
community and serve so what actually we do is uh we train the student uh how to
use uh astronomical instrument like a telescope planet sphere Su dials
and uh we train them how to use the instruments and uh they go to the
community and all different different schools of their community and train other students uh in their um uh and so
here's the motor like mentor to menty and menty to
community so here are the uh others program like uh empowering them uh
before going to the community uh like uh s some soft skills hard skills and how
to handle the telescope how to uh handle the sun dials planisphere and how to
beave the morally and different things uh before going to community and uh teaching uh and come in different
schools so I had my lots of time with these girls uh like uh it was like I
always give my Friday times uh to them and teach them a different uh things uh
going to their schools and taking their time in their clubs uh so there was one of the uh
astronomic Club in one of the school and was I was taking it completely in every
Sunday is their academic Prospect and uh I used to take a two hours daily and
teach them about the astronomy and how to make the planet spere Su not only
these but different things like how to make the telescopes and I recently uh I
recently completed the telescope Workshop telescope making Workshop where we made a 60 mm uh reflecting telescope
and uh uh 6m reflector telescope and uh 90 mm okay uh reflector
telescope uh so uh this is the message tables where student were making the
satellite models paper satellite models there a wind s that is solar science and
the satellite model is ready here and they were making some kind of planets model by their own and there are the uh
sixth fifth grade student uh which are nearly 11 to 12 years um and they were engaging uh their time
in Shing astronomy with me and unfortunately about um due to the my
University time I could not continue with them and they were so sad for that
okay so for in my place uh other will join from our uh Society from our Nepal
Astronomical Society uh so here is uh like old space
week uh which is celebrated in October 4 to 15 or 4 to 10 uh so uh I was
coordinating in my Province uh here in Nepal uh here in
20232 and it's been like a three years I have been coordinating for this o space
week in my Province uh so uh there was a biggest Festival of Nepal that is called
thei uh where we celebrate the god of power okay so where we take the Bliss uh
from the Elder and like put the tika so there's a festivals so which is
mainly celebrated with the family and relatives but uh I plan to went in the
orphanage home and disable home women's uh and celebrate the say Okay celebrate
my festivals with orphanage uh kids and teach them about astronomy and observe
uh they observe the Saturn Jupiter and um Moon of course and sun
uh so I went there and they enoy really enjoyed it and they were so curious
about it and they ask me about the different opportunity around and like I
said about the global star party and they were like amazed oh we can also like can we like uh like contribute in
the international platform or anything like that okay uh so I said like uh you
should like continue your continue your like curiosity and work on it sours the
opportunity around uh so here is another event that is uh H in one of the schools
uh these are the high school students uh using how like learning how to use a
planet sphere so uh these are the kid from The
Orphanage homes uh and who were really interested how to know like how know about the universe about the astronomy
and uh these are the orphanage homes and disables women uh which is serving for
about 15 years uh for for her uh she's the disables woman who serving for like
15 years for these kids um in the oress
home so not only this uh I I often different workshop and seminars and
share about uh in different topics mainly I share that how to like how to
make your career or how to get interested how to search about opportunity or like how I did uh so uh
is I was interested uh many of the interested uh peoples just leave this uh
field by saying like there's no any opportunity here or by they don't like
resource properly or anything uh but I suggest them uh you will like uh
research like you this will take some small small steps uh toward your career
uh to make it successful uh so not only this uh there are lots of programs I
have been doing uh like I'll be busy for all the weeks and there was a one
program that NASA SP challenge which I have taken participate and uh for that
challenge um we have taken the challenge to act as a travel agent for the space
tourism uh so recently uh I my website get down so I could not show it here but
in that uh uh challenge in that hackathons we prepare our website and
flares and where we have given this like we acted as a
travel agent and prepare all those uh entities and all the information of
about the different solar systems and we also uh make the plannings and how this
day plannings how how many days you were going to plan in this um all this uh
buzs and everything we made it uh like we acted as a travel agent and prepared
that project probably I can show it uh next in next GP uh
so uh these are the things I have been uh doing uh in this one years
and uh so not only this I was giving my other times for observation like night
SK observations in my community and uh like working with all this uh in the
like I'm going to like upgrade my up uh like Po two junior members to under so
now I'm I can't give my full times but I'm giving I'm still planning to
continue my uh doing through onlines or like connecting with those girls and
connecting with those kids where I used to uh give my time uh earlier and uh
like uh at least give my time in Saturdays in Holiday here in Nepal uh or
like give my astronomy continue my astronomy here in my
University that's wonderful I didn't uh wrote a poem now but I just wrote a
small line that is a little girl asks what's the things you d for a little
girl asks what's the things you diaper and I just stun over my head to the thinking star is
smile thank you thank you thank you so much stt well
that's wonderful uh the uh the programs that you do with uh uh Nepal uh you know
the with the naso group uh how how many presentations are you guys giving a year
do you think uh here in gsv yes so maybe it's been uh astronomy pro
programs for for kids how many times a year are you doing that so it's been a
two three months we make uh like uh for this uh astronomic club uh I have giving
continue my time every Sunday every Sunday wow okay well that's a lot every
Friday in for those girls uh there is the girl schools Pak Girls School uh so
I went there and give my Friday time birday wow that's uh uh very selfless of
you so that's that's great that's great well deep T thank you so much and um uh
you know congratulations on all of your work that you're doing I know that you're changing lives so and uh uh
you're always welcome uh to come back on global Star Party thanks so much okay go take care
okay uh we are going to um uh get our
segment from the astronomical League we have uh don NAB uh who is um uh you very
active amateur astronomer and has been for many many years um and uh we're
happy to have him on Don uh you're going to be talking
about the pladies star cluster yep y all right wonder I'm gonna share my screen
okay nice Quest are you got back there on your desk uh it's a joy it's it's a
joy really is all right so let me slideshow from
beginning should be coming through yes it is okay so so I'm gonna talk about the opposite
end of the spectrum from what David Aker talked about he talked about an incredibly obscure open cluster I want
to talk about probably the most famous open cluster in the sky and that is the plees you know I wasn't sure what to
talk about this week but last Wednesday I was out with a telescope a dobsonian
with my wife and we were looking at things in the sky you know Jupiter Saturn Caroline's Rose the usual and we
set on the plees and I thought you know I'm going to talk about the plees because I'd like to know more about it
and I bet a lot of people would so this is about the plees a short presentation before I go into that I do
want to announce that uh December 1st is uh the next Al live astronomical Le live
and we're going to have Jay Kelly batty who is uh he was over 40 years at Sky and
Telescope uh editor and you know an incredibly knowledgeable astronomer so
he will be talking about mysteries of stone Chen that's uh I think you know it's covered by my uh my menu bar that
the top but I think it's 7:00 on the December 1st Eastern Standard Time so the plees uh if you walk out any
evening December even January February and look this time of the year lookit to
the east you'll see this tiny little dipper up on the sky a lot of people mistake it for the Little Dipper they
don't know but it is this open cluster the plees now when I looked this of course
this view is from palar Observatory so we don't see the net velocity but this is about the field of view I would get
on a dobsonian it's 1500 millimet I have to put in a 48 millimeter
eyepiece pretty unusual eyepiece but to get this kind of field of view what you have to do that gives me about 30 power
and uh you know when I'm looking at the plees if I can see this little double star in the middle clearly that's a sign
to me I have good seeing uh it's really a better B binocular object um probably
the best best one of the best views I've ever had I like to obser with large binoculars the best view I ever had was
somewhere a year ago at a star party and it was a windy night and the plees had
just come up over the trees uh so they were low on the horizon the wind was blowing but the the Stars twinkled like
Christmas lights and one of the most amazing sites I've ever seen in a binocular telescope so uh so I've always
I've always been in love with the c so U known as the Seven Sisters OR Messier 45 we'll talk about who this Messier guy
was in a minute you know I was researching this and you can probably find several dozen names for this this cluster okay uh it's
so famous it's an asterism it's not a constellation part of constellation
Taurus and 44 444 light years away you know listen to Dr Bo's presentation
these stars are our nextdoor neighbor uh they're they like walking out my door than I'm neighbors they're so close uh
in the cosmos so uh and it is one the nearest star clusters to the Earth and it is the nearest Messier object to
Earth and probably the most obvious cluster the naked eye this time of the year in the
sky so simulation show that the plees probably formed from something like the
Orion Nebula okay uh m42 U so maybe in couple hundred million
years m42 w now be another set set of plees they expect it's going to live
live another 250 million years and then just because of the galactic neighborhood it will dispersed and we
will have lost this beautiful little uh beautiful little cluster so plees ancient Greece his name
comes from ascian Greece probably from clean to sail that's because the cluster was very important to define the sailing
season in the Mediterranean Sea I'll talk about that in a moment in mythology the name was used
for the plees were the seven Divine sisters supposedly deriving from their mother pleon meaning Daughters of pleon
but that can't be true because the name of the star cluster was almost certainly first and they just invented pleon to to
explain it so uh that's where the pleades came from we'll talk about this
greenish gold disc in a moment but uh M45 we abbreviate Messi as M M45 played
an important role because of uh working on calendars two elements about the
plees are very important first and it's still true it's near the ecliptic in the
sky and second especially important for the Ancients they didn't have clocks they didn't have calendars they uh they
could tell that the asterism marked the Vernal Point start of spring so they knew when they could uh start sending
their their fishing boats out again uh so this is evident in northern Europe
This is the nebra sky dis going from about 1600 BCE we'll talk about this in
a moment right here so the disc is bronze now this green is not green paint this is the patina that bronze forms
when exposed oxygen especially for that many thousand years but about a foot in
diameter and uh weighs five pounds but his gold inlay again as I said before
dated back you know a couple thousand years ago the early Bronze Age so they're not certain if this is the moon
or the Sun and certainly this is this is a crescent moon but here if we count
these Seven Stars everyone agrees this is the pleades okay so the dis was found on a
hill called mittenberg in Germany so Babylonians named the plees m
m which literally means star star okay and uh they were at the top of their list of stars on the ecliptic here's
Homer uh some Greek astronomers considered the petus to be their own
constellation uh but they do they do have a role in Homer's ilad and
odyssey maybe you're old enough to remember I certainly am it's not that long ago but a movie
called um Close Encounters of the Third Kind this is Devil's Tower it played a
uh a big role in close encounters with third country because that's where the aliens came down to talk to us but in uh
Robert Burnham's celestrial handbook he notes a connection between Devil's Tower
somewhere in the midwest I forget in the southwest I forget where exactly but uh the kyowa lore says Devil's Tower was
created by the great spirit to protect seven Native American maidens who were being pursued by giant
bears the mes were placed in the sky as the plees cluster and the marks of the
bear claws are still seen here on Devil's Tower and this story is also told if anyone has seen a NE grass Tyson
in the new version of Cosmos he tells a whole story about the legends of the
pleades uh being placed in the sky and the Bears clawing Devil's Devil's Tower
we'll talk about another couple of the I mean we could spend an hour talking about the
various mythology around the plees but we won't so so to find the plees
remember this other Legend okay the legend of Seven Sisters chained to doves and sent into heaven to avoid the
clutches of Orion Orion was chasing them so if you look at where Orion is the
plees always rise before oryan because they're trying to get away from him so that's the way and the plead is so
obvious it's simple to find uh but I use capella and actually I took this last
week this was Jupiter when I made this chart um the easiest book uh Mark in the
sky is probably Taurus the V of taurus the B and Al Deon then you go up to the
plees so on Japan so we're going to talk about for a moment you know we we've been saying Seven Stars all along in
Japan they called this uh with bosi meaning six stars okay the cluster is
now known in Japan as Subaru this is the Subaru telescope 8 meter scope it's on
uh Mona in Hawaii uh for from 98 till 2005 it was
the largest primary miros scope in the world monolithic primary miros scope so they named this Subaru which is the name
they use for the plees in Japan and Subaru again you count six stars they they they took the pley
cluster when they took five companies to form one so anytime you driving around you see Subaru he seeing the Japanese
depiction of the plees Galileo was the first one to view
the plees through a telescope and he discovered the cluster contained many many stars that were too dim to see and
if you look if we count here in this this uh this drawing he made there are only six stars so again we historically
we see Seven Stars listed we also see six stars Galileo only drew the main six
he included total about 36 that he saw and this is back in h 1610 so six or
seven um depends how good your eyes are I guess now are they a cluster or are they
more like um a cluster I think of that is a chance alignment is the uh coat hanger cluster
those stars are not next to each other in space but just by chance alignment looks like a coat hanger so back in 16
1767 John Mitchell calculated that the chance alignment of so many Bright Stars
was only one in 500,000 so he concluded the plees must be actually a true
cluster of stars in space that are physically related and in fact since we've been able to analyze their motions
we found that they are moving in the same direction and they are a physical cluster they're not like not like I
think every constellation in the sky is a pure chance alignment of near and distant Stars the fetes are a true
cluster so this Messier 45 this name Messier many of you probably know but Charles Messier he was a comet hunter
and he got tired of seeing the same fuzzy object in the sky thinking was a comet when it actually was something
he'd seen before so he cataloged these objects I think he did around 105 and we
had added a few it's 110 total but he published his catalog in 1771 he named
it Messier 45 so along with the Ryan nebula The Beehive cluster you know the fact that
he included the plees was is under some discussion because most of the objects
in fact if anyone in takes the astronomical League Messier program and you where you have to look at all these
objects and find them you'll know that most of them are much much fainter than the than the plees or than the Beehive
cluster or the Arion nebula so they think that Messi was simply patting the
books okay he wanted to have a catalog larger than Nicholas leis de he
published a catalog with only 42 and mess wanted to outdo him so he added
added the the plees it's pretty obvious when you look at them that they are not a comet but uh it was a game of one
upmanship I guess back then so the core cluster is about eight
light gears and these 14 14 Stars we can hot blue stars you can find they say
someone with good eyes can see 14 I can only see a couple I certainly can't see seven I might see four or five uh when
you look at this Arrangement it is indeed a little dipper REM Minds you of Ursa Major and Ursa minor some people
get confused think it is the Little Dipper which is not but the uh the nine brightest stars
these are the names of the Seven Sisters and then here are the parents
Leon and Atlas and uh you know just beneath the plees we saw in the star
chart is the hiades that that is the V of tarus the B those are sisters of the
plees here are the seven plees so that's a lot more about the plees you
know I got my information from the classic Terence Dixon book Night Watch and a book that a friend of mine gave me
about the the messier objects when I was pursuing the astronomical Messier program so uh now we know a lot more
about him wonderful wonderful you know the um
uh when you look at um uh quotes or stories about the pladies
there's lots of them on the Internet and people have been mesmerized by this Con
know this asterism is what we would call it as amateur astronomers uh but uh I
have as you say many many times been out under the stars with friends and they say oh look there's the little dipper
you know and uh of course it looks like a a tiny little dipper sure
does but U you know uh Ursa Minor uh is
actually much much larger in the sky than than the huge yes yes but it's it's always a
joy to see it in the fall because we know that not far behind is Orion with that beautiful nebula to look at right
and I have seen uh visually uh you know provided you have enough aperture and
you have transparent enough of the sky and dark enough of the sky you can actually see some haze around these
stars and so um you know it's uh of course uh in astrophotographs especially
astrophotography done today where they shoot you know 20 hours or 40 hours or even you
know 80 hours of of objects like like the plaes you see an immense amount of
nebulosity there so does yeah yeah yeah so anyways thanks for bringing that uh
to the global star party and uh Dom um you talked a little bit about the
astronomical League um I just want to tother Horn a little bit more you know
the astronomical league is the I believe the world's largest Federation of astronomy clubs over 300 clubs belong
under that one umbrella and over 20,000 members uh so it makes it uh amongst one
of the largest and most important and oldest uh uh organizations of its kind
so um if you don't belong to the league you you can join a an astronomy club
that is a league club and you'll automatically be a member um or you can
become a member at large and you just go to astr league.org and join up so thanks
for for coming on again Don and thanks again to the one thing I would like one
thing I would like to add to Don's wonderful presentation on the plees it brought me
back to 19th August 1962 I was 14 years old getting ready to
go as a patient to the Jewish National home for asmatic children in Denver and um I went up Before Dawn and
I drew uh I think 40 or 50 stars in the plees using my little three in telescope
wow and it was really really special and uh it's it's really it also
when you brought up the picture of Charles M it brought a really personal
feeling because when I looked at a picture of a fellow Comet Discoverer and
um someone who meant a lot to me in my early years as as Observer of the night
sky so I just love this presentation about the plees I'll never forget it
thanks Don thank you David yeah thank you that's great all right um so let's
um let's go to our next speaker uh we have um Robert Reeves uh with his
postcards from the Moon presentation uh Robert is becoming our Guru of of the of
the all things lunar and uh uh we really are pleased that you come on to Global
star party so often thank you well I'm pleased to be here and uh to spread the gospel about the big bright light in the
sky that um many deep Sky Observers is a void and I say that's a shame because
the Moon is something to be embraced in addition to everything in the Deep Sky
it's a an object you can see from your own backyard you don't need to go out of town the moon laughs at light pollution
but um as I give my presentation Scott will notice I'm not covered with sawdust
right now all afternoon I've been building the uh the cabinets that I need to store
several hundred pounds of these lunar orbiter photog that I that I inherited the original images that Johnson Space
Center uh used back during the Apollo era and now many of them are mine and I
need to take care of them so I'm making proper cabinets to uh to to to um keep
them out of Harm's Way because these are really historical artifacts but um today
well the theme is the size of the universe well the first stepping stone in measuring that of course is is how
far it is to the Moon uh the Moon is the only object in the sky a celestial
object that humans have traveled to so it's the very first tentative step uh science fiction not withstanding the
reality is um getting to the Moon is hard and uh it's been 50 years since we
sailed there the first time and hopefully within my lifetime we will go
again but um tonight um my theme is a walk in rain you remember last week uh
we walked in the clouds by um um touring Marin nubium the U ocean of clouds the
sea of clouds I mean excuse me well today we're going to tour the Sea of rains Mari embrium on the moon so let's
see if my adventures with screen share work and hopefully you are now seeing my
yes it works whoa this is amazing you're get you're becoming an expert at this
too well let's see if it advances this is this is my my title card of course
postcards from the Moon and we don't need to see my menu here postcards from the Moon of course is what I post every
day on the or most of days I try to do it every day on Facebook a new picture
that I have taken about the moon uh uh with a u description of what's going on
in the picture why it was significant to me so I hope you enjoy me on Facebook
and enjoy post cards from the moon so moving on MAR embrium itself is the huge
circular Maria that forms the man and the moon's left eye now I choose Mario
embria because tonight um the lunar phase is just beginning to expose the
Eastern side of Mari embrium Plato crater U Aristotle I mean Archimedes
crater uh Cassini are just roaching into the sunlight and over the next two days
the rest of U Mari embrium will appear so U this is a um a
significant chunk of lunar real estate Mario embrium appears to be the largest lunar sea although it's actually the
second largest uh uh oceanis proelium the ocean of storms just west of it and
still in Shadow in this particular picture um is twice as large um almost 2
million square kilometers but Mari embrium I think somewhere in the territory of 800,000 square kilometers
um it's more um centrally placed and we we see it more direct uh oceanos
proelium is extremely foreshortened and even though it's twice as large as embrium um it's
it's visually is insignificant and doesn't even contribute to the uh the face of the man on the moon whereas
embrium very prominently forms the man on the moon's left eye now the action on
embrium is primarily around the rim uh we've got Plato crater up at the top U
the gash of the Alpine Valley going through the Alps mountains Cassini crater the unusual little um looks like
a bird's nest with two eggs in it uh Archimedes crater the appenine mountains
arching on down to U ostanes crater and of course t uh cernus crater just south
of Mari embrium but it splash of rays so huge that the Rays splatter out onto
Southern uh Mari embrium as well um it's a fairly well bordered Maria and
that's because the rim of the embrium impact Basin the original Basin on the
moon blasted out by an asteroid almost U about 3.85 billion years ago um this is
the rim of it and a basin is nothing but a gigantic crater um almost 800 kmers in diameter in this
case so it's no longer classified as a crater call it a basin but the rim of it
is what forms these Mountain chains around the rim of the Moon around the rim of marrium the Alps mountains the
top the caucuses on the uh Northeast the appenines to the southeast and then the
um carpathians uh separating um capricus Crater from the body of um Mari embrium
um not too many large craters in Mari embrium um Archimedes being the largest
over here in the East um L timus and Lambert um moderate size craters um
noticeable only because they're so isolated out on this vast empty plane of
Mari embrium and then up uh further north U um two smaller craters at the
mouth of um sinus arhm and we'll investigate that here shortly if we go
the right direction oh come on there we go um now we're looking a little bit
more closely at the Northeast side of Mari embrium um Plato crater just
lapping at the shoreline and uh in this Sunset View the shadows and sunlight
emphasize the mountains the Alps mountains um on the on the northeast the
uh Caucasus on the East the beginnings of the appenines arcing Southward and um
Archimedes crater uh similar to Plato in that it is lava fil it is uh uh
completely paved over inside and they both C were created or the their
Interiors were were created by a similar process not by lavas overflowing the
edge of the crater spilling into it but pushing up from underneath and flooding it from inside um Tao oh Plato crater up
at the North the basalt is about 600 meters higher than the basalts of Mari
embrium uh the uh basalts within Archimedes not quite so high more more
closer to the uh the level of the uh the surrounding marot uh a curious thing is these three
craters here uh right in the center of it is a feature we call sinus
lunus and that is named after the Russian Luna 2 spacecraft that impacted
this area in September of 1959 the first spacecraft from Earth to arrive at the
Moon uh so right in this area is where it all began the space program the Space
Race to get to the moon um was initiated um Russians reached the moon in
September 59 uh we started a scientific push to
also go to the moon and ultimately ended up with Apollo uh let's move on a little bit
further below um the stist lunus up here on on the
upper left U we see the beginnings of the appenine mountains and the snake
likee re of um Rama Hatley Hatley re this is the Apollo 15 Landing site back
in 1972 and a mere 13 years after Luna 2
crashed into the moon deliberately it was not supposed to land it was an impactor uh crashed here 13 years later
Dave Scott and Jim Irwin are walking on the moon U just south of that
region uh not this is Mari embrium up here on the U upper left uh then through
this this straight in the mountains uh we enter into uh Mari seratus the Sea of
Serenity a part of which forms the man of the moon's right eye and moving along a little
closer uh Robert I I have to tell you all of these images are just breathtaking I mean they are just
amazing well I love to see them like six foot by 8 foot on my wall here you know
I I routinely print many of these up to 13 by u u
19 I'll have to get one from you sometime oh yeah I'd love to send you some yeah yeah beautiful
wow spectacular I also hear you have a good book on on the moon uh well as a
matter of fact uh you'll get to 10 Penny commercial when we get a few more slides in here uh so uh if if you do enjoy the
Moon if you like what you see here if you know somebody who's enthralled with the moon uh think about them at
Christmas time and uh I'll show you a real good book that you can give them but in the meantime here more more of a
closeup of the uh um Apollo 15 Landing site uh the first true science mission
where they stayed for three days and deployed the lunar rover and buggy it all around that area and uh uh went
right up to the very edge of Hadley re and this was all done on live television
um I I remember watching and thralled as as each science sto they realign the
antenna on the uh on the lunar rover back toward Earth and we re see live television of their Explorations so um
it was really quite a time uh scooting further down the appenine mountains uh
always said if the appenine mountains were put on the moon for one reason it was to point like a finger toward osin
crater and cernus crater down here cernus isn't technically in Mari embrium
but close enough that it has quite an effect on on the embrium where you see
the the spray of secondary craters splashed off even across the uh uh
Carpathian Mountains and into uh Southern um Mari embrium and uh now a
closeup of those Carpathian Mountains down on the southern Edge um that's of
course cernus crater um at sundown and
uh looking at the U oh this more or less how Central embrium probably looks
tonight or early in the morning uh with a sun sunrise just stretching across it
Plato crater at the top just breaking into Sunrise uh a aredes at the bottom
of spitsbergen mountains poking up right here um the u ms Pico um Pyon is just
off the edge there but uh right there where my cursor is circling that little
feature looks like a hammer it's a um little mountain range t-shaped mount
range I call that Thor's hammer because it looks very much like mulier uh the
Norse god Thor's magic hammer um but the Curiosity in this image is this sweeping
wrinkle Ridge arcing down uh from south of Plato crater getting down to The
Spits Bens arcing off to the west and then we pick up at the next picture uh
this is Western Mari embrium here wrinkle ridges arcing up offshore dorsam
Heim uh the big fat one here casting a shadow uh this is uh indicative of a
buried Basin impact ring underneath the uh the basals forcing up buckling up
these wrinkle ridges and then of course sinus aridum U rather large uh impact
crater Basin that formed on the edge of Mario of the of the um embrium Basin and
in turn flooded with Mario basalts to become a Horseshoe Bay now if this
crater uh this impact had occurred a little bit further west and not merged
with Mari embrium it would have created one of the largest craters on the near Side of the Moon and uh look how the
wrinkle ridges look like frozen ocean waves washing into this Horseshoe
Bay and a bit of a closeup of sinus arhm itself the sinus arhm translates as the
Bay of rainbows which is uh very uh prophetic because we're next to the uh
ocean the Sea of rain Mari embrium um
Mar foror is arcing northward portions of oceanis procellarum beginning to
appear on the um Sunrise Terminator the western side of Mari embrium has no
defined border like the Eastern side where we saw all the mountain ranges uh it merges seamlessly into Oceanus
procerum so moving a little bit further along and off the beaten Trail this is
actually related to marrium this is the final slide um even though we're now in
territory well to the West excuse me well to the east and south you recogniz
tus arzachel um um um alonsus in the middle arachel the
bottom um these are Landmark craters in their own right and not associated with Mari
embrium but what is is see the vertical gouges running the streaks
ripped like cat claws uh scratches uh through the crater rims uh this is what
we call the embrium sculpture uh these are clues that back in the late 1800s uh
let the chief geologist of the uh uh us Geological Survey U to conclude that the
embrium uh Mari embrium the the the Basin uh cradling it was created
by a mass explosion and it hurled chunks of material Mountain siiz blocks in all
directions and we can see um in this picture splashing across the crater rims
where where this debris tumbling across the face of the Moon literally ripped gouges in the face of the moon so um
this is all um evidence pointing to how the lunar basins were formed by gigantic
asteroid impacts so getting to to the end I
always say there is much to love on the Moon the Moon is my playground and I
invite you to come out and play with me and uh you can do so by going to Amazon
and U doing a title search exploring the moon with Robert Reeves my name is in
the title specifically to differentiate this book from all the other books called exploring the moon and U it can
be on your doorstep in two days so uh I hope you'll get a copy and uh go from a
lunar novice to a lunar Authority in 300 pages so uh I have enjoyed very much uh
visiting with you I will stop the screen share if I can here it is and uh say
thank you for letting me join you again and uh okay all right well that's great um we uh
um are coming up against um our next speaker uh Maxi FIS uh in Argentina I
think he's finishing up dinner though so I think what we're going to do is we're going to take a 10-minute
break here and then we'll come back with Maxie uh who should be ready to u to log
in at that time but Robert thanks again for sharing all your insights and stuff about the moon uh you know it is
um you know they they should have a regular television show or you a series
of documentaries where you uh you get on and describe uh you know each each uh
section of the Moon and I would love the way that you can I mean it's just it's it is really a privilege so actually I'm
doing two radio shows this weekend ju doing just that except by radio it's I
do it by verb you're stunning images by radio yeah well either way face made for
radio but you know so anyhow I know the
feeling thank you very much Robert okay thank you bye bye okay okay so um uh yes uh we will we're
gonna go and take that 10-minute break right now and we'll come back with maxi
FIS uh where he's going to show some uh images of Jupiter so stay
tuned
for
for
[Music]
[Music]
[Music]
[Music]
[Music]
oh
there we go unmute myself anyways uh welcome back to the
136th Global star party uh the size of the universe is the theme and we had uh
we've had some amazing uh uh talks and lectures uh starting with um uh David
Levy's introduction of Bart Bach who gave a uh 30 minute long lecture about
the size of the Universe um uh you know and uh uh also with David AER deep T gam
Robert Reeves uh I'm missing some people here already uh but um Don NAB was on uh
uh and uh we are now going to Maxi
FIS uh down in Argentina who's been concentrating on the biggest uh planet
in our Solar System Jupiter Maxi uh thanks for coming on to Global star
party and I'm sorry to interrupt your dinner oh Scott hello good night
everyone well thank you for inviting me yeah I just have dinner so well I'm full
right now but well like like you say Scott I was ER we are in the planetary
season so I I could B er a new er camera
that ER give you a little more details that I had with the dedicated
astrophotography camera to theep Sky objects so in this case is a planetary camera it's a
CW 60 662 a color and the size of the pixel is
more small than the one so it will give me a more sharpless details on on what
I'm going to what I want to capture in this case I work with the H Ines F6 and
B the 3x but let me share my screen so you can see what I was doing
uh let me close this one and this one yeah okay do you you see it
yes great well basically ER this is was last
uh last Sunday night here's my doia scope about the
equatorian M but here's the Astro camera I'm pointing to in this case is Jupiter
right there and there's the the almost
the highest point that I will get from here so it's almost 40 degrees above the
Horizon so it's pretty low good but still
anyway yeah and and I think in
two in 2030 in a couple of years it going to be
rising again more higher in the in my Senate so I have to give the chance now
so because more later I think it's going to be more low than this but anyway I
grab my equipment outside put the the scope and everything and point to there
because I want to capture the Great Red Spot ER but H it was more like it was
coming from here at that time so I said everything and start to doing videos of
one minute each other and I did almost uh like you can
see 146 videos of one minute so almost two hours and a half but between
someone ER I stopped of recording because the the scene it wasn't perfect
but at the most preious time I had the most the very most seeing that I ever
had till last night so when I get all these videos I process this in PPP is a
free software to to not buy the de buy the the sensor
and and get all the the the structure of Jupiter get centered so then I went to
outo stard this version is the last one in in
beta but it works really fine this is the
4.0.2 version and this is an example of what I get this is only one video
that you can see is almost almost kind of of stable but then if I go more beond
is more rough so I only I did in this video a
11,340 frames but only I stack the four% of the
that so when I do this I get this result
for example um this is what the three
3 oh here uh
30 is01 yeah this is the one
so if I open it you can see shup very circularly some
details but it's very blurry so I went to another software
that called re tax this is I think an old one but it works really uh really
okay and it's free you know and you you
have only to put there and then start to practice with the
wavelets okay because that it will going to give you more fine details or more
gross details so I was practicing changing seeing what I what what I like
to to get to not to do too much because it
were going to be awful so I saved the the last the
set and you can see how how it's going to change and when I see this I say okay I
have a lots of details and and I have to start every single video to to get more and more
details but remember one thing like us or in planet Earth Jupiter has a
rotation so the planets ER one day in
Jupiter is are n hour from us
so rotates really fast so in every single minutes I have a lot of changes
of position so for example
I I did this well I I I didn't yet but didn't do it yet but you can see here is
hoer and when I get play I'm going to show you the the all almost the videos that I did
that how fast in every frame hubit rotates
so it's if I stack everything I will
have I will have it everything um St
and without focus and like movement so well in here in this case I have IO
passing by in occultation by Jupiter you can
see wow it's going there and then it it disappear so and then I when I did this
it was almost 2 and a half a.m. and it was really low and I say okay that's it
that's all for tonight I put I grab my equipment inside again but I had to
process everything so I wait for the another day seeing how it works and what the the
the frame what was the the best to to to get stack in this case so in this case I
work with wi shos to measure the the size of the planets and of course if I
get Le less Zoom uh for example
I I was outside H for example in this
one here you can see there's this circle is IO that it doesn't see on the field
of view but if I open another that is
see there it is so this will help you to get more
centered and say of the position of where you are in this case I'm minus 60
degrees in longitude but latitude minus 34 because I'm in in the sou hemisphere
and well the video does the the time and the data in
UTC so I you only have to measure every
single frame to well I do a blocks of 10
frames and I did a one two three four five six in this case was 60 V frames
but but the best ones was in the second and in the fourth ER group of frames so when I
stack those in this case in when I go to their
rotation I add the the objects and let me find it
[Music] Z for example I will do all these
ones I will open it so if I open someone you you see the measure the
measuring of the of the planet if I go to the next one it's going to be in the
the the another position and then the software we're going to do is a get
in a a prom of all the videos to get in this case a a position like it was in
3 and 06 a.m. UTC but I started to record this at
0301 and finished to 031 so is in the middle we have the the
result so for example if I go this I create a new
file where I want to get the result
save uh and then compile uh
pictures you can see here is the the rotation of 10 images and is almost 9
minutes so here I have the the rotation of those 10 frames in almost 9 minutes
and then if I go to that file is going here
here and open it here in Rex again where I in every single frame I work with the
wavelets when I put this it will go to be more rough more much more details but
because the sharpening is working with something that was sharpen
before so I have to H dis increase the the volumes of the wavelets so I of
course you have to start again to see what I get what you can get of more fine details and I find
in this one is more fine details but you can see
almost the the the Great Red Spot and everything don't worry of the colors
because a in this case it's like a greenish color or bluish color but when you get
RGB balance because the way the white balance it changed so don't worry about
it uh so what I did it was stck the the
better second group frames and the H better fourth group frames and the
result was uh here best and
here it was the it's practically you can see here
again the same problem I have it I'm I'm sharpening something that was sharpened
before so I have to this increase again so when I get
this you can see one here the the Great Red Spot is in the middle and I have the
the core the core and the nucleus really
there and the shape of the clouds going fine don't worry about these lines
because in the addition you can put it out and the result of
that was this image uh here the T
yeah here's the final result of course I change the position because I like to
put in in that position but you can see here the the core is
more colored I work with a try to not get too much Focus because the noise it
will going to grow so you have to balance everything to get more
a a picture more nature of of what it is
don't get too too much further so well I was
ER yeah try to do it five or six times again and
again and again it's like an obsession you know but when you get this results
because I think I never had it when I started only with the cell phone I could get details with another
scope and everything also when I get the F4 telescope and the dedicated camera I
have those but these kind of details ER I could never get
it uh let me open here here's without too much color so
what I get was a get
a a a light AUM frame to put it like a
mask and then work with the colors if I
increase the the saturation you can see how color is going to increase so I
put it and then I think if I put this
another one it's going to be really really tough so I would put it
less to get yeah I I like it that way
and let's put a little more contrast so basically it's practicing
with everything and and well ER you know it's
perseverance because I I don't have the good
weather pronostics because I have a lot of wind but I have this window of of one
hour yeah and the this the the stabilization of the of the of the scene
was incredible I could see some details ER going through so I had to give a
chance so well uh this is what was what I was doing
this couple days I I was uh little off
of doing deep Sky objects and I was was working a little more with planetary but
like I say here is more difficult for the angle of the altitude of the object
so it's I is not like the lottery but some
kind of but I hope someday I can win the lottery
okay I hope you can too that's great okay all right well thank you so much
Maxi that's that's wonderful and uh you know I can imagine your planetary work
will get uh better and better but uh um then then you'll be competing against uh
the likes of people like Damen Peach and uh no oh yeah never know you know so
yeah I I think I don't like to say it's competition because every every single
or every each astrop photographer has the their way to work and true every
every work depends of is more subjective than
objective so er D peit has a of course
the equipment and the skies and the knowledge and the experience and of
course he exactly I I I I never I never could
talk with him but I hope someday like with Christopher go
or Eric zenach that I think is Australia but there are a lot of reference that
they do that you can say okay I could get there if they could I could get
there of course the equipment also sometimes give you
some some limits so you have to expreme
that lemon to get all kind of jewi but it has a limit so you don't have to
worry to get all the more fine details of the Perfection now you doing
astrophotography and and doing science with that for example if in this case
I record videos to get all these frames but remember one
thing the this is our solar system this is our neighborhood basically so in
Japan a couple weeks ago they capture the the flare of the impact in hubit of
course that's amazing and you do that when you are
doing this kind of stuff uh because you are recording videos to get Ines of Jupiter doing pictures but you maybe
have that lucky and of course when you have the a the the transition of of a
moon passing in front of Jupiter on this case behind of that is still astronomy
because you can demonstrate that we are not only one that moves in the sky is
everything moving so in a small scale but in a huge scale
also that's true at unbelievable speeds Maxi thanks very much and nice work Maxi
beautiful work yeah it's great stuff those colors popped when you uh did that
that one color change where it white balanced out you could see instantly the
amazing colors that you captured yeah that's why you don't have to worry I
worry it because I I I I I worry when I say those what is green or what is like
yellow but it's the white balance so it will going to you can change it don't
worry about it it's excellent very nice Maxi as
usual as usual thank you guys thanks so much thank you guys good night by bye
bye okay um coming up next is um uh
Robert or Bob Fugate um Bob has been on several Global star parties uh but it's
been a few months since he's been on so we're really happy to have him back um
he is uh of course uh of uh someone of
uh Adaptive Optics U and Laser guided uh
uh artificial star fame um and he's done much for the advancement of the science
of astronomy uh but he's also an amateur astronomer and a fantastic
astrophotographer and he has agreed to come on and show us some of his latest work thanks for coming on to Global Star
Party Bob okay thanks Scott um thank you it's
been uh it's been a while as you say and uh I'm just kind of Blown Away with all
of the presentations tonight it's really really a great party and thanks so much
for putting it all together thank you thanks for let see if I can see if I can
share my screen
um and get the presentation started here
does that look like it's working yep you're in presentation mode okay
um I guess I'd like to get rid of this Gizmo at the top here but I'm
not quite sure how to do that um okay
um we don't see anything but the slide so right the problem is it's kind of
kind of blocking my view I see I I can move it down a little bit sure I think
there's a way to turn it off but not sure where it
is I'm not much of a um Zoom Ranger it
it looks just fine it look fine so as some of you may remember or know I now
live in Phoenix which is kind of um in the middle of a super white
zone and um my sky quality meter typically reads
17.8 so I'm I'm eager to I I I have been trying narrow band of course and um have
had some success with that but I'm eager to get out when I can and um see uh where
where I can go and find um other locations so back in June um I
went to the White Mountains uh east of Pac Arizona with a friend we rented a
cabin there and um we
um uh spent a few nights and my my primary instrument is The
Takahashi Epsilon 160 Ed it's a hyperbolic
Newtonian and it it has incredible Optical quality as long as you can get
your camera Square to the to the optical axis and at the right focal distance
from the homea corrector um it doesn't have a very good
focuser and so I replaced it I've replaced the stock
focuser and um I've been using the Pegasis
Rotator because ultimately I'd like to set this telescope up as a remote
telescope and operate it uh remotely and for doing that and in order to make good
compositions I need to be able to rotate the camera however the Rotator does tend to
add some tilt so um that's an area of
concern and I'm using chroma filters in a zwo filter
wheel um and I also have a device that allows me to position the
camera uh in order to get get it Square to the optical axis the camera is the
fullframe zwo 6200 uh mono camera
and in order to make it portable I'm I'm trying the one of the new strain wve
Drive mounts uh this one is the ioptron is very similar
to um the zwo am5 in terms of its
capabilities uh this one has encoders and um to help with uh the
periodic error and and with guiding and I run the whole a whole rig off of a
lithium iron phosphate battery which lasts actually a couple of
days so um in that expedition to the White
Mountains I was able to get what most consider a very difficult Target this is
the um flying bat and Squid um ou4 is the squid
and this was um nine hours of Total integration but seven hours on 03
alone so this is this is a very difficult Target I was quite pleased that um the um setup allowed me to get
what I consider to be a pretty good image uh yeah in um in August um I went
to the heila National Forest I have a friend who has a cabin
there that's embedded in the forest and land withd drawn from the forest and um this is a really
incredible site it's very very dark um
so in this exposure is a 40 mimer uh lens on a
DSLR and um the exposures for the meteors were 2
minutes each and um the exposure for the
landscape was 15 minutes so um in order to get enough
light on the landscape mostly from the Milky Way that's how long an exposure I had to
make and it's one of those places where you're stumbling around in the dark even
after 45 minutes there's a couple of smoke trails in the image uh there's one here that's
very noticeable and um I was with a few friends of course and I probably missed
quite a few meteors due to my inattention and drinking beer and and having a great time looking at the night
sky awesome so then in October I traveled again to New Mexico to uh
magdalina and um as a sort of adjunct member of the magdalina
Astronomical Society um a group of us went to the
edge of the uh Eclipse path uh it's an an It was an annular eclipse of course
and the idea was to try to maximize Bailey's beads uh so this was the group that
drove over a very rough road um for quite some distance to get
to this location and this was my setup I had a
um Nikon camera a 2X Extender on a 400
millimeter f2.8 lens on my ioptron hm44
Mount and um and my trusty lithium
battery and so I just did a rough uh polar alignment using my using my cell
phone um and uh for the short durations of the exposures and so forth it worked out
quite well so um this is kind of what the
field looked like and I was shooting um I was
shooting um exposures rapidly so that I could put
a movie together of the encounter and here is that
movie um you can see the first pull away of the Moon from the
edge of the Sun and then as it approaches again
just literally seconds later
um so that was um that was quite exciting to watch and to
record so um shortly after that in the next days that followed um the magdalina
Astronomical Society sponsor a star party every year called the enchanted Sky star party it's in Ptown New Mexico
which is west of magdalina about an hour drive and uh sort of a hotbed for
astrophotography and astronomy these days and one of one of the people there
one of the astronomers there has a 40inch dobsonian and uh we got a private tour
uh during the star party and here he is looking um getting things lined up and
ready for the night observation it's the largest DB Sony and I've ever looked through and uh things are very very
bright you can see quite quite a lot of depth and on the way to pytan we nearly
were run over by a radio telescope uh as some of you may know on Route 60
you drive right by the VA and uh they happened to be moving one of the telescopes along the the railroad
tracks and it it moves along at a pretty good clip and um and I'm I'm not sure
what the protocol is because we were able to get by you can see how close it was to the road there when we approached
it and so that was kind of exciting so after the star party um I
returned to magdalina to a location where I'm where I'm anticipating the
possibility of setting up my telescope as a remote one and I just wanted to do some test exposures to see you know what
what it what the guy might be like so this was my setup and I spent
two nights uh making um uh taking some images and the object I looked at was
VDB 152 called the wolf's cave nebula it's fairly popular object
and um from David's talk tonight I I plotted on here the object He was
discussing uh pism Marino one and they're very close together in
the sky actually and but I think it's very small compared to what I was looking at so
with my short focal length telescope I probably couldn't do very well but I might look into that a little further
and and give it a try it's very a very interesting object so any rate here's VDB
152 um this is um 8 hours and 30 minutes um of total
exposure and it's um most of the filters L RG and B plus hydrogen
Alpha and this this part of the sky and sephus in general is just loaded with
stuff so uh dust and nebula and
um both reflection and emission lots of streaks of hydrogen
Alpha um so it's quite an interesting part of the sky so I I um zoomed in a
little bit here we'll look at the middle first and um the dust and
reflection um in background round of hydrogen Alpha this this bit of dust
down here um these bright stars in the neighborhood it's just gorgeous and as
David had mentioned the sky is just littered with stars I mean they're
everywhere in this you know because we're right at the edge of the Milky
Way and here's the upper part of the image um this this part here is H be in
538 and this object I'm not really sure about it was first thought to be a planetary nebula but I don't think it's
considered to be that anymore and more hydrogen Alpha
here just really gorgeous stuff to look at and then in the upper left we have
lbn 532 and LDN 1221 and this is a very dark uh dust
region with lots of trailing dust again more hydrogen
Alpha and then in the lower right part of the image we see all this dust that
is in wispy like clouds just um you know I'm I'm kind of uh hopeless because I
just like driving around in these images and looking at stuff for you know
literally hours and just trying to see what I can find and see in them it's
just really really gorgeous part of the sky so in November uh I changed up my
rig a little bit in trying to get it more balanced um I've always used this
counterweight um The Strain wave gear folks say you should put a counterweight
on if you're going to exceed 44 pounds uh this rig weigh
about 42 pounds Believe It or Not mostly because of these very heavy Rings which
I have recently replaced uh the two rings weigh nearly
10 pounds but the big problem is that most of the weight is far from the axis of
rotation way down here in right Ascension and that generates a large
moment and um it probably is stressing the
specification of about 20 Newton met or 40 Newton met uh for this particular
Mount so one of the things I did was I tried to rotate um this big globule of
mass that consists of the optical train to get it lower in the um you know
closer to the axis and also put my guide scope down on the side here and uh
another view of that is shown here where I'm uh again trying to lower the center
of mass of the arrangement and um but what what I
learned in when I went to my next location which is Mule Creek New
Mexico um the the temperature got quite low down to 12° fah minus 11
C and the spec for the mount is minus 20 C but when when it came time to do
um when it came time to do the Meridian flip at Transit uh the mount would not lift the
telescope over to do the flip oh so I was quite surprised and my friend who
was with me had an am5 his did the same thing it would not do Meridian flip even
though even though it's within the maybe barely within the
spec so um that's um a little concerning and I'm
doing more investigation on that and um discussing this sum with
ioptron so here was our setup uh there were three of us who ranted uh a cabin
there and this cabin is on a a lady's
Ranch um she has 440 Acres which she says is nothing because
across the street her neighbor his Ranch is measured in square miles five miles
by 27 miles wow and he has cattle on the
ranch uh one one cow per 40 acres
so that's will support a lot of cows apparently but um this is this is a
stargazers paradise because as you can see like in the hila this is just south
of the hila National Forest uh in W Far Western New Mexico and um it's the sky is very
pristine and um dark so this was our set up we had uh
telescopes on this side of the driveway and I was set up over here the green
light came from a pilot light on a power supply that was sitting beside the wall
here and even though it wasn't very bright to us visually you know in a in a
30 second exposure in your camera it does show up so here's a time lapse this is 11
hours uh you can see us running around and every occasionally a light go on we
come out with our headlights on if you watch closely you'll watch you'll see Meridian flips on these
telescopes they happen very quickly because um it's such a long time lapse
this is 11 hours and 55 seconds well 11 hours displayed in 55
seconds there was when I had the problem with the Meridian flip
there was a Meridian flip over
here and um here's the Big Dipper the handle of it anyway the North Star is
here here's daytime and then it clouded up in the early morning so the clouds
waited till morning and we we locked out so the other thing I did with these um
exposures was I made a star Trail image um so this is what happens when
you put 10.8 hours of 30 second exposures that's 1300 exposures together
in Photoshop that's beautiful and um all the colorful lights and you can see the
telescopes flipping over and pretty cool so here's one of the images this is
IC 348 in Perseus um this is the IC 348 region
here this I call a Dusty Inferno because the uh hydrogen Alpha that's being lit
up here probably by this star atic um this is a 3.8
magnitude uh Blue Giant and of course it's very bright and
really lights up the region here so I've zoomed in some on this
um here's the ne the the reflection nebulosity of IC
348 I couldn't find a specific designation for the Hal Alpha
region uh or the dust here and if we look at some of the
details in the reflection nebula it's it's just
amazing not sure what's going on right
here and here's the hydrogen Alpha
Inferno with um and you can you can see it through the dust even very cool yeah it's beautiful and
then the other Target I shot was NGC 1333 which is just nearby
that's this object here and it's just loaded with dust uh it's just
everywhere uh this is 8 hours and 30 minutes and here is here it is at
100% um NGC 1333 this is some sort of Hal Alpha
emission again some very dense dust
and um the lower right part with more reflection
nebula very intricate and complex patterns in the dust I imagine Bart Bach would just be
mesmerized by these things yeah yeah it's you know we we live in such a great
time because with relatively simple equipment we can see this sort of thing
in one night and it's just it's just totally mind-blowing to
me so um that's what I had to report on my recent adventures with
uh uh let's see what's happened
here uh your did I stop sharing you stopped sharing yes sir okay good uh I'm
done okay was wonderful it was wonderful thank you thank you so much and um uh
Bob uh you know we hope to see you again on a future Global Star Party okay
thanks so much thank you all right okay so
um up next is uh marello Souza uh down in Brazil uh marello as I've mentioned
on many a global star party is the editor of uh of Sky Up Magazine he is
the founder of the Lewis cruls uh Astronomical Society down in Brazil and
uh uh he is um a force to be reckoned with in astronomy Outreach in uh South
America in fact in the world he's had amazing uh events uh where uh thousands
of people come together to witness uh the celestial mechanics of uh eclipses
and um uh you know com and all kinds of things I I think that
the most um memorable uh uh uh presentation he's given though was one
where uh a farmer had found a meteor or actually witnessed a meteor fall and
found the meteorite okay so uh really amazing and uh so marchell has been at
this for quite some time uh you know uh popularizing Astron teaching young
people uh about uh The Universe And getting people young and all and old
involved in uh learning more about science Mar Char thank you for coming on
to Global star party and I'll give you the stage thank you for the invitation quite
is a great pleasure to be here thank you for the kind words thank you very much yes and today have also a special week
because this week we are also celebrate the B
of Ed hble I'll share my
screen okay here let me see
if one moment okay this is
H most famous poetry in Portuguese that is f p
that's a Portuguese for us is like Shakespeare
for you in in English is a very famous poetry and he wrote as with another
name the a that's very famous here he said this juniverse is not my idea my
idea of juniverse that it is my idea what we do when we stud univers
yeah I don't know if same problem that I have with Shakespeare in Portuguese maybe if you
read the the text written by in English because he wrote in
Portuguese I don't know if he the samea that we had you have but is very famous
one he has very famous and I I will talk some things
some about some contributions for the model that you have about do the best
expansion thas right Galileo with the telescope saw
that first first time that in he that have so many stars in the M but Thomas
right had the first person that imagine and our
galaxy he imagine this he publish this original theory of
new hypothesis of the universe and this book he explained the of mil as this one
an optical effect doe to our imion what locally approximate to a flat layer of
star imagine a layer and we are inside this thing layer
then when we look up and down we see many less Stars when we look in the
other directions we see more stars then is a way to explain why we see the milk
way only in a part of the sky because we
are inside looking inside a th layer then is something fantastic imagine
this and now this is more about what he said the
many cloudly spots is just perceivable by us as far we thought our St regions
in which those visible luminous space no one star particular constituent Bo can
possibly be distinguished it's a fantastic idea and if idea that we begin to imag
that we live in a vision with other stars Vision in the sky our galaxy and
with this idea later Emmanuel C the philosopher the famous philosopher that
imagine that it's not only one region in the sky we're having another maybe we
have another reion in sky like this if we imagine that is like a
coin then we can have another regions in
in the space like this the idea that the first way that he imagine the galaxies
how we know today then he call Iceland's Universe have many different iseland
Universe now that are different points like the one where you live in the same
way now this was proposed by Kent from the idea from for original
imagined by Thomas W this fantastic has
also using this idea he how he imaged the milkway with the
information that he had d by real R
and everything changed with the contribution from two
PA one is in his leit that's she fantastic astronomy and
also she was very good in mathematics he work as a woman
computer here with another woman women in the past he's a fantastic
mathematics and she was responsible for this feury oh
sorry that help a lot Hubble she
discovered in 1912 the relation between the intrinsic brightness and the period of safe variables then this is something
that allow us to know the distance of these star from us because if you know a
relation between the intrin brightness and we compare with the brightness that
you receive from the earth you can imagine the distance of these start then
is a way to make a good measurements of the distance something that herb
uses then here like this here have the
brightness variation of Delta C is five and four days and you have the
Peri Luminosity relation for variables here and has of world knowing the period
of the variation of the bright sa variable it's possible to know the
distance of the star with something fantastic
uh and now we have they doing H in this short history
that he born in November 20 yesterday in
1889 and here is a published by m
observator of Ed H he's
born and what as we talking about the size of universe you need
to H here is anim analyzed by
H if help of that's Fant
history here you see here the saat where is my mouse here you can see the saat
variable star in this galaxy they didn't know that it was a
different galaxy they imine like a nebula inside the milkway with the
measurement made by Hubble about using the sa star he
measure the distance and he Pro that the distance of this Galax Andromeda from
our galaxy was greater than the size of the milk wave then it was another galaxy
and these are published in 1923 using the
work originally developed by
init using a star that's something
fantastic and then now we need we have we need he needed the help of the
spectroscopy that's a very important to for astronomy and with this know the
spectrum of elements like hydrogen oxygen each element has a different
Spectrum then what hble did each chemical element has istic lines and
analyz analyzing the spe we know the chemical composition and also the
velocity of the stars from us this something fantastic and who was
responsible with the results used by hble veg Le that's that also Bor in
November 11 November V Lea he was the
first person he image that he analyzed the first measurement of radial
velocity for Galaxy and discovered that distant Galaxy are head
shifted very distant Galaxy I had he discovered this
first make this measurement associate the looks of the
Galaxy with the red shift this is a contribution made by
this guy and Ed H working with M
Heros he discovered a proportionality between Galaxy distance
and that head shifts then the Galaxy more distance has
a bigger head shift than then he he would uh is a way to imagine how
universe is and also is a way that he
we after he announcements we can only consider universe
expanding because the gala the Galaxy that are very far from us are moving our
away from us then how if you look in different directions all these G that
are very far from us are moving away from us then this means that universe
expanding that's the way it to then after this had in the before models of a
sta Universe after the results published by Hero we begin to consider only models
that's considered that University [Music] expanding and
but in our local group you see here H in
local groups of galaxies is most important the ER gravitational fields
then this galaxies is not a moving away
they are moving in the same one direction of the other the the galaxy
moving direction of the M because the gravitational field is stronger than the
the force that moves this galaxy to be distance one from another then I'm
talking about groups of Gala or that are more dist from us far from
us and here have the expansion of universe this model that
return the idea of the Thomas right now then we
imagine that we living in a layer a
layer in a universe that's SCH and is expanding in four
dimensions something that this idea and based on the data initially presented by
Hubble put forward the hypothesis that Universe would had add a moment in the
past with extremely high values for it density and energy from that moment
universe begin to expand expand then is the idea that you have today of the Big
Bang is the orig of this expansion of the universe this is the model that you
have today that everybody knows about this kind of expansion and you have two
different moments one the first moment because it's not the didn't come from the fairy you
need to put with hands there because it's not possible to have disolution
from the F the gravitational Theory from Einstein is the
inflation in a in the early Universe in a short moment the universe expanded
very past and then begin to to expand in a
different velocity and nowaday we know that he expanding faster than we have in
we predict in the theory and then now we
need to consider another kind of force that is making the universe to sping
faster then for our of universe this is the idea that you have the called the
size of the universe and distance we here near us in the earth we have our
solar system we having the nearby Galaxy stars in in our galaxies we have the
size of the milk wave we are talking about 100,000 light
years of diameter have your local group that we
talking about two and a half two and a half million light years our local group
reg we belong to a a super cluster of G
of local groups here the vou have local super cers and the here is the idea of
the observable universe that we know today but what is fantastic is that
you don't know what is 90 and
five% of all the matter and energy of the
universe the what we know like M matter like we have in our day
life is only uh less than uh one
% we're having Stars off of 1% now matters and heavy
element only zero. 0
3% have elements from what we know of the universe 95%
7% is associated with dark energy 25%
almost 25% with the dark matter that you have to consider to explain what happens with
the rotation of the Galaxy B in the B of the
Galaxy and then something that you don't know then have a job for astronomers for
many years because most of the model of don't know what
is looking far but you not know what's
happening then thank you very much for the attention SC is a very short history
yes yes cover a lot of ground and soon we have a new edition of Sky app I hope
that after the than Thanksgiving next week and the Happy Thanksgiving for
everyone yeah thank you so much thank you much thank you very much for having me
yeah no problem we hope to have you next time so thanks so
much okay uh our next speaker is none
other than Dan Higgins of AST World TV and they're getting ready for the astop
paloa event Dan it's all yours hey everybody can I I'm sorry my
hair is a little bit of a mess so I I apologize my I've been I've been going crazy here so uh uh Scott how's it going
um can you hear me it's good we've had a a really interesting uh Global star party and starting off with um um you
know uh Bart Bach uh who uh gave his
presentation in 1957 thankfully he recorded it so we could play it tonight you know so um but
it was really interesting to you know all joking aside uh to have David Levy
who got to know Bart boach um dve David Aker also got to meet him through David
Levy and so just to have some uh that thread of you know people who knew
someone that were uh talking about who passed on in 1983 um he was a hard worker from what I
understand he actually died at his desk so wow wow yeah so uh constantly
studying the universe but unbelievable yeah yeah you know I'm sure they'll be
they'll be us too but um sure well yeah I'm I'm probably gonna die I'm gonna die in this chair right here that's what I'm
yeah the groundbreaking breakthrough that uh anyhow just yeah so
um so are you are you are you excited about uh uh this event um that you got
coming up is it um um is it becoming overwhelming is it just as do you love
doing this I I love I love doing this and you know what last year was I really
didn't know what I was getting into I mean an eight hour plus event long time
to be broadcasting it's a long time and thank God it wasn't you know you know it kind of breaks up the monotony if you're
hosting because you know you talk for 20 minutes and then somebody else talks for 20 and it goes back and forth but let me
tell you um we had some awesome guests last year and uh we had uh Molly
Wakeling Shan neelson Wayne Parker M we had everybody and now you know it looks
like it's getting a little bit more of a you know this is only the second one we're doing and um you know now we have
yourself Trevor Jones Dylan O'Donnell Stacy DT Shan Nielson masters of picks
Insight again um I who else uh Charles Bracken Dr sass for my telescope is
going to be on we got really good door prizes this year I mean uh this year
Charles Bracken is giving us a uh signed uh autographed book of his and uh Dr
Whit made a book a couple years back called the visible Universe uh so that is going to be a good prize not only
that but he is I don't know if you've seen this picture and I I don't have it on the page I didn't even think I was going to bring it up but it's an all Sky
picture it has something of about 190 hours worth of data over the entire
world and the Milky Way just goes like this and it's the whole Sky wow and it's
a ridiculous he's giving us a he showed it at um at Nic last year and he's
giving us one of those to give away as a door prize as well it's a print or it's
a print it's a print yeah yeah it's huge it's ridiculous um wow it's it's I think
it's like three feet by two feet I mean it's like a banner it's big beautiful um
Dr sass is giving us a premium image set from my telescope from from one of his
uh chili Scopes so last year last year he gave us um what is it um uh what's
that glob um uh uh damn I forgot it's the biggest
glob in the South cranny 247 was
it 2 cany yeah T4 I think it was 247 yeah okay so I think that was not the
biggest uh Omega is definitely the biggest but I mean certainly a big one and a very bright one you know right
very bright very gold and beautiful picture yeah um um also uh we're also do
so one thing that we did last year and I I didn't mention this last week and I wanted to mention it this week um we are
selling um t-shirts tour shirts like for the show so it has Astro paloa on the
front and on the back has a date and everybody that was on it and all of the
we did the same thing last year too and I really didn't promote it as much as I concert it's a concert shirt yeah okay
but here's the thing all of the proceeds of the buying of these shirts go to a
donation to an astronomy club subware in the world so and if you want to be
involved in that if you want your name on the list to be eligible just email me
at danastor telescopes.com and you could I'll put you on the wheel
we have the spinning wheel that we do if you watch if you've watched the show before you know we do a lot of giveaways
um and Dan at Asal telescopes.com and just say I want to be on the list I'll
put you on the list and we're going to give that check away uh on December 9th
at astop paloa so that's put I put your email address there in chat so they can uh
participate in that and what what else uh as far as Ms of pix Insight also have given us a lot of free masters of pix
Insight classes so if you're interested in taking your um image processing using
M using pix Insight sure to the next level you can get a class for
free just by going to AST web it's a different website Astro web.com
and then you sign up for the Astro plad door prize okay we have about 50 people on
that on if you want if you want Scott I'll email you the information it's going to be a you know I put the I put
the link right there chat AST World web.com correct y okay and uh who else
is gonna be on Simon Lewis is gonna be on Wayne Parker is gonna be on it's going to be a lot of fun it starts at 2
o'clock you see it on the bottom right right there I think um astala 2 on
December 9th yep 2 pm 2 pm start and last time it was supposed to close out
at 10 Eastern it ended to be about 11 11:30 and you know at the end of
sometimes these things run a little bit long yeah that's cool that's live that's live TV that's what happens so that's
right so it's gonna be a lot of fun come and hang out with us we had over 2,000 people watching last year uh so we're
hoping to break that this year so come on hang out with us even it's just for a little bit whoever you want to watch the
schedule um I'll email you to schedule there I made the schedule um and you
could put that on there and uh everybody could see who's going to be on when and it's a t tentative schedule for now but
it's pretty much solid but uh everyone's been uh been really gracious with that
time and and the presenter it's going to be great it's gonna be a great time so come come hang out that's wonderful you
know uh uh more um more people in this business should be doing what you're
doing Dan so I really appreciate the Outreach the education the camaraderie
that you guys have you know you show like the best side of what uh amateur astronomy our community of amateur
astronomers is all about you know so uh you share the you know all your secrets
and uh you guys don't have any secrets I you basic basically we we save some we
save some but those are like private things right I it's like what's in the sauce in the Big Mac you know you're not
going to share everything you know you got to save a little bit you know you gota want him come back for more but you
know what it is all about the come right and I'll be dead honest with you I probably learn more from the people that
are on the show in the chat and talking about the chat and pointing stuff out
live on the show then I probably relay on the show so I mean we it the chat
drives the entire show we do shows every Wednesday and every Friday night
depending on if I'm traveling or whatever because you know how it is Scott of course all over the country got to travel so so um but everyone it's not
that we travel so that we don't do shows I mean yeah well well Eric's been doing a good job doing the shows occasionally
when I'm not able to direct them like with all the all the pump and Circumstance that I like to do but uh
sure you know but hey it's it's a lot of fun it's a great time and uh you know just come and hang out with some some
half decent people that's right more than half more than half decent so that's thank you Scott for letting me
come on and uh and tout ask I hope everybody comes down I appreciate it I know you're running supporter of of what
you do and uh we're glad toh share um you know these details with our audience
so so hook up as with Astro World TV learn more about astrophotography if
you're not doing astrophotography I don't know why not you know you'll be amazed at what you can get uh
astrophotography is more advanced than ever but it's also easier than ever you
so uh and when you have people guiding you like these guys do at AST World TV
you're going to get the images of your dreams so I'm sorry I gotta say I'm
gonna be I'm an honest person for those of you don't me I hate you Astro images of today I hate you all because
because like hiding that you were repressing we can get the same image in 30 seconds that it took you five hours
five hours that's called that's called technology that's called technology
advancing some of your some of the astrophotographers also said you know
what this is crazy let's invent or figure something out so that more people
will get into the because remember astronomy started out as mostly visible you had to learn how
to build a telescope or you had to do what John Schwarz do and draw your images that was as photography but now
we're in a golden age where a lot of people coming into clubs we did a survey
at our club L BR most of them over half if not 60% want to learn
astrophotography or want to do more astrophotography y so that's where now the astronomy is still there you can
still do a lot with a pair of binoculars but what you're and John I mean there's two
different sides everybody wants to capture their own version of what's going on in the sky or night and
absolutely you know you come in love it is a love hate I mean I I I love
them I can see stuff to add to my drawings but I hate them because they can do it so quickly and I can't see
that like that but you guys don't get photons so not like we do
no it's amazing I mean it's just it's just out of control it really is you
know you sit there and you get like a A unistellar or a stellina or you get something like that you hit the button
you go to bed you have four glasses of wine you go grab your phone you take a look oh let me save that is that is that
wrong is that wrong were tracking trailing is that why was the wine or was it f you don't have to have four glasses
of wine but maybe two okay so depends on how much pain you're in for dinner two
for breakfast right there's your four but I will say this for everybody I
don't know my fingers in the camera but for all of you one of the Astro imagers out there we still want you to learn the
night sky because there's only so many images of the learn that's right yeah
and that's what's going to distinguish you that's what distinguishes Dan Higgins John Schwarz the other Astro
images out here that's what distinguishes them even I know hav had
the moon on you know the moon uh think what distinguishes pictures is yeah I
just said the moon thing I'm gonna com we all give back help show the
glory yes and we know what we're looking at David iker's interesting objects how
are you going to find those unless you learn the night sky so that's your challenge out there don't just point it
at the same thing you know or the Milky Way you know lot a lot of Astro images
that want to sell they want to make money you know shooting these objects
well you know in order to do that you sometimes you have to get lucky and catch something extra orinary if you're
the first to shoot an image and you happen to catch a supernova that's
erupting you you know that's where it becomes a scientific thing so yeah so
yeah so wor your spot is safe because you've been doing it for 20 years you
might decide hey I want to shoot something unique that you know I don't see a lot of on the internet oh yeah let
me go after you know speaking of images those images from Bob fug were awesome a
lot of them were never seen before so yeah that that's just really cool stuff just on a
side note and I'm gonna do a little plug here before I get off and I'll get off okay but uh John yes you know three out
of of four people have something in common on this on this picture right now you know what they all are what's that
we love Scott well well we do do that was a good one you
got relationship I knew I it wrong three three of us have been on as
World TV so I gotta get you on wow that would be great man I'm all in here you
go I I'll send you an email later we'll get you on thank you wow that's an honor appreciate that AB absolutely absolutely
we'll always look for more guests I'd love to uh get on there and give you
know give some more back sharing is is The Ultimate Gift you
know for me sharing is caring iing is caring Asom appreciate it you know
although you know why I do this anyway it's all in the honor of I give everything credit
to the creator of course you know we're gifted with absolutely yeah there's a you know
you've got you've got a Vatican Observatory you've got some that are watching that may be atheist what brings
us all together the night sky the universe I wonder that's right it's
regardless of your higher power we are still all joined as Humanity some of us
give you know give all due respect to the Creator but our regardless of belief we
still agree on one thing the oriion nebula is absolutely beautiful it's awesome that's right and and so so
there's that that's what brings us all together we're we're in a in Period and
Scott if you don't mind I'll hurry up and go through my quick so guys we're
going to move on we're gonna move on but Dan thank you so much we will tune in
watch Astro paloa I'll be there and I know you better be else I'm gonna have to fill a half hour so okay yeah we'll
fill it you don't mind if I run over do you I might start from the beginning I'm going to oh sorry yeah I'm gonna start
sharing okay while the introduction is going on if I can I guess take everybody
have a good night thank you Scott bye bye all right and it's all yours
Adrien all right so let's see if this works all right I'm sharing my screen so
I'm gonna turn this way and we're gonna go to Google photos so one thing that
I'll just go real quickly this universe is great but Mankind's involvement in the
universe is becoming pretty obvious when you take a look at this image over Lake
h on and you see all of these colors I captured it with an H Alpha camera and
of course I think my light in the truck just went off so it's okay I'll go in the dark again it's about these images
and you're seeing the dust Lanes of this side of the Milky Way I like to shoot the Orion side of the Milky Way because
it is often targeted than the more
familiar Galactic side you'll see images like this and you'll see them paired but
let's start with this let's look at that light B that's Colorado Springs in the distance where the balantic center was
near back in um midt when I was in Denver and you'll
notice the theme is light bones are and it makes it a little tougher to view the
night sky you got a light B coming from Windsor over here and some from Port
Heron in Michigan so what happens is compared to that last image you saw
notice how much of the sky is just missing and then you've also got some
green in here which I do believe to be Sky glow so there if you point directly up at the
sky you get a uniform image and it's just based on how dark your sky
is Canada over Lake YY you see various light domes we're looking at Windsor
we're looking at Detroit and that sickness region we just saw there's a
sickness region right there there's very little of it and um and then a
panorama looking to the Southwest and Southeast where a line is rising
right here it makes for a beautiful image now you got a light Dome and you
look at this and go what's that big bright light dome right there we look at it again you partly we're composing with
this um stick and we're looking at the Winter Circle which you've got some
definition some detail some cloud and a huge light though well where I'm sitting
when I took this image Point peely National Park in Canada we're looking to
the southeast and if you look at the city southeast of Point peely you're
running to Cleveland Ohio 50 miles across this Lake that light Dome of
Cleveland Ohio is so great that it absolutely washes out this section of
the of the Milky Way now you say well what else is there that this happens to be the part of the
Milky Way when we talk about how big the universe is here's a line if we could
look through the lake and down into the Horizon you would see the melenic clouds
this is as close as they get to midn Northern latitude
and you can barely you could probably barely see them in Florida I'm not sure
you'd actually see them in Florida you if you if you how high R is above the
Horizon that's how below the Horizon the first one of the maganic clouds is so we
come tantalizingly close but we don't get to see it and and when you live in an urban area
there's a lot you just don't get to see because you don't go Horizon to Horizon
there's that signus region and then this part of the Bulge but in a dark area where you can go Horizon to
Horizon everything looks more magnificent and I'm pretty much using the same settings to do these captures
here you see this area here of this part yep um in Black
Mesa and you know the hor because you can go down to the Horizon you see this
region which I do believe is I want to say that's a northern co sack but I would have to look that up um that dark
region in that part of the Milky Way and somewhere in here before I turn it over
to John to take us all out there is a picture I'll show this one because I
think a lot of folks panoram I always you know you just have to plant
it and then the other side of a in a dark side is what I'm hoping to show and
all these images I keep them because I use them to get ideas for my next
images over here this is how you see the universe with your own eyes you see a
lot of stars you see a Ry Rising you see the lake that's a that's a true to your
eyesight image and I think a lot more though should be taken you see that I do a lot of Imaging with you know hydrogen
Alpha but sometimes it's worth it just to capture what you see because a lot of FKS a lot of you that are watching
you're captivated just by the stars and we ought to recognize that especially when we want to use our images we don't
just want to use images to you know we repeat our theme sometimes wood pointing
at objects in the sky to show the connection between Earth as being a part
of this big Grand universe and then you know the the galactic arm over here but
um there's so much there's a lot to see here in a darker area in Michigan you
can see more you see more of this stuff but there's a lot more to see and a lot more to explore and we don't just want
to show our pictures and you know just for the beauty of it we sometimes want
to show our pictures because we want people to realize that all of this is
out there and it's fascinating it's fascinating even if you
got a storm well take a picture of that you know Earth WEA and imagine what this would be like if you were on Jupiter and
then try and see something this is a naked eye visual type of image
here and um and then finally all of this is sitting in that
region when you're at a place where you can see a lot more because you don't
have light you may have Sky glow but you don't have light domes now all of a sudden you're looking at all kinds of
detail that you didn't know existed the PES the California everything just pops
out and um and it also let you know when you take closeups these DS you know
these deep Sky objects in California is a very popular object where and so is a
rosette but these things are just look how small they are compared to the rest
of going on in this region of the Milky Way they're a lot titiner when you
compare to the entire that's the entire size of our galaxy you've got a whole
universe out there that you can look at so so I'm gonna end that here let's see
if I can yep stop by sharing there and um yep and
hopefully you know hopefully through the images I'm able to sh one let's see this
turns on I'm able to share one you know how
important it is to um to understand what you're looking at when you get
interested in this hobby you know go ask questions about well what's really there
what's not there you're taking the pictures you know and you try not
to you try not to do it just for yourself it's for me it's often better
if you're doing it so that you can share it with others ensure you know if the
images are beautiful someone will probably tell you you should print those you should sell them there's absolutely
nothing wrong with getting paid for some of your work of course not right but if
it's your focus I think it does a little bit of a disservice to the sky itself
because if you couldn't if you lived somewhere if we lived on a planet where you couldn't see any of these there was
just constant cloud cover across the entire planet you lived on something like Venus and you couldn't see the sky
like that there would be nothing to image there would you wouldn't know it was out there so I really think a lot of
credit when it comes to astrophotography visual astronomy a lot of credit needs to go to the sky itself
with out that Sky you know do we even build telescopes do we even do we come
up with the technology and the knowhow to understand how to capture light how
to understand that how to build machines that actually rotate and track at the
same rate that the Earth Tracks and then to realize some it feels like it's very
slow rotation is very slow but when you get into the hobby all of a sudden it
feels like it everything in the sky is moving faster than you wish it would especially if you're wide angle you want
the Milky Way over something but all of a sudden the sky is moved in the four or
five minutes that you've tried to capture and now you have to move your camera in order to get the composition
that you want for your shot because the sky moved and if you're lucky enough you can get realigned you can you know you
can align yourself with the North Pole if you know where the Little Dipper is even in a Starfield Sky it can only help
you so that you can get there get your shots and you know then you share them
with you know whom ever loves a night guy like you do yeah Scott that's gonna
be it for MEK I am going to turn it back over because Wild Man John Schwarz is
waiting in the wings to close this all yes he's there he's there that's right I'm in
a yeah I was explain in that blue nebular light yeah I'm preserving my
night vision because being visual I have to protect my rods and
cones um from you know Bright Lights you know being on this platform it's like
I'm Star Struck you know being able to uh participate with some of the greats
and and some amazing artists and photographers
Adrien everybody on here spectacular and and it's a real treat and I look really
forward to these Tuesday nights and um it's just a great thing
you know we're doing what we love hanging out with the great astronomers
and great people in the audience and hanging with Scott and uh learning about
this universe how big it is it's really big really really big this big well how
big is it John it's not big enough yeah right but uh
well you know it is um uh I I think you've done a lot of astronomy Outreach
John uh and a lot of the people on the show have and some of these Concepts
where you are trying to um take the uninitiated you know people have never
really looked up at the sky much you know uh or even look through a telescope you start to uh give them some details
about you know uh distances to even some of the nearby stuff like you know Saturn
at almost 900 Million Miles Away uh you know and they can see the
rings around Saturn and stuff and all of a sudden you just see like this little This little light bulb go off in their
head that you know they're looking across this expanse of space you know but that's just stuff in our own
Celestial backyard you know and so it's um uh you know once you start talking
about how many light years away something is and then the the concept of time you know and all of that so uh
which actually we're going to get into in the next Global star party so um the age of the universe and uh our
perception of time there's cosmologists that believe that time is Just an
Illusion so um so you know these these things are the concepts like this uh are
tough to get um to wrap your head around you know and and uh so it takes takes
people like you John and uh you know do astronomy Outreach and study this stuff
to help people kind of cross that River so you know it's like with the Hubble
telescope and then now James web it just shows you and um the Chandra and all
these new telescopes this new one that just came out it's not as big but it's showing you amazing things in different
wavelengths you know other than our vision can see we only get like a small
sliver of the spectrum yeah our our perception is already
skewed you know we're not really getting the the you know seeing the the full
reality of what things are you know so it's it's a mindboggler you know
every Star party we go to the question always comes up and you know we we tell
them how far do you think this thing is and they're like we don't really um know
I mean it's got to be real far and it is so far away that you couldn't even
believe it's like the light coming there left before the dinosaurs were even on the planet it's just
really you know it's a time machine it's a time machine and and you travel as far
as you can see light and you you know that's based on how much magnification
or where you're located and the size of the aperture you know that'll give you a big
jump and a big advantage in trying to figure out how far it
is but it's so far that I don't think
our minds can actually comprehend the distance that is actually
there but it's very difficult it's very difficult absolutely amazing Bart Bach
was using uh things like um uh you know thinking of the Milky Way and the the
the sun's rotation around the Milky Way is like a a Celestial year for the sun
you know um so you know it's uh it helps to kind of have analogies like that but
because the num as Bart box said the numbers if you start talking about miles or
kilometers the number is so huge it becomes meaningless to most
people you know we we like I said we're at Star parties and you know some people
actually break it down in the parking lot and they'll say well say this is the
sun right here so if you were to look at Jupiter it would be right there and by the time they go all the way out to
Pluto I mean you might be halfway across the world it's just on it's such a large
scale as far as making a Solar System model yeah yes right and um you know and
that's just right here you know the Sun the light takes how many minutes to get here it's like eight minutes and then
you know the outer planets it takes time you're seeing them as they were minutes ago right so it's kind of crazy but this
is a picture of my friend Andrew and hopefully I'll get him on here you know he was doing some really good drawings
he was just kept staring up I go dude what are you looking at and he's like man it's just amazing how bright the
Milky Way is it's like you can touch it but it's just so far away and you know
it's just intriguing that it it's something you could never grasp you know
in your physical state but I mean if you could go faster than speed of light you
could probably do anything you wanted you know this is the other star party
and you know it's the same time we all get together and then we take a break we have our coffee and usually that's the
question we always Ponder is is uh how good everything looked and amazing and
and it's so far away and you know when you get the great nights it's really a treat to see yeah but you know from here
on Earth we look we wonder now just throw yourself out even further and
you're out you know looking at galaxies I believe this is 23 million light years
M51 another version beautiful and just to be able to reach that Galaxy and see
it and that's actually a a close one one of the closer ones would be spectacular
to be able to get to that distance and close the gap and then now you're out in
space you've been flying for 20 months at like a quarter speed
the light you're not even making it D you're not even like a tenth of the way
there already people are growing older you know time is slowing down the faster
you go the farther you go you can go till it looks like you'll never get
there you just keep going and it just seems like it's always out of your
reach and you know this is the James web the farthest picture we have I think
it's 28 billion light years back and
that's that star they found it's like the biggest brightest star they ever recorded and then there's a Galaxy
cluster there that is pegged at 28 billion I think but if you're looking at
those faint red galaxies in the background they're red shifted so that
puts those galaxies at like just a couple probably billion years after the big bang or
whatever I I know they're trying to debunk that I mean probably eventually they may figure out how it really works
but it's just a great instrument and the further along we go in time I believe
that we figure a little bit more out about you know the age of the universe
and how we're a part of it and just why we study it because we need to
understand you know how this works and um that's going to take some time but I
think you know with all the great minds working on it and everybody involved in
astronomy you know you never know who could figure out the the distance or how
it works true but that's the reason why it's so important to U you know live in
a in somewhere where you're free to study
you know uh what you will and um uh you
know there are there are places in the world where this you know studying science is repressed and I think it's
one of the biggest crimes in humanity myself you know so yeah it it's such an
important thing that we understand because eventually you know our planet
won't sustain or the sun will come to the end of its life and at that point
you have to make a decision and that is should gone long before that yeah you know a lot of songs
come to mind yeah um should I stay or should I go go but I'm gonna um change gear so that
was my um little presentation for the title uh the size of the universe so now
I'll go on to what I wanted to do and I'm basically going to talk about the advantages of the digital how it's
really helped me out and uh giving me a great ability to to share and create
works as if we we're traveling out there and and trying to give you a closer look
and a more spectacular View and also brighten your day and make you like you
know what you're seeing and just create great stuff so we can all enjoy it but I
was an artist in college had a little carire total all my
portfolio all my Works everything I did have have a shirt but
it was partially burned um but I made it you know so so I I just basically before
I remember St it just tells you why I kind of shifted you know I always thought digital was cheating um I just
because you're not drawing it and you're you know you're using a picture or you're you're creating stuff on a
computer where you can manipulate it and um you know I fought technology for a
long time but you know you have to embrace the things that are tough to do just way to
paint another way of saying right so and then you know you have to label them but
this is a standard format this is how the purest and I want to make something
clear that sketching this way is the absolute purest form because it's just
you the telescope the eyepiece Under the Stars you're sketching with a
little red light with a pastel powder or you can use a a pen or a pencil on white
paper and um you know you draw your circle on your card to make your template so you can label everything and
it just tells you the object the constellation the telescope the
magnification location and you know Sky quality just all the things that you saw
on that night and it keep a record like an observing log but it's a a picture record too which you know you can go
back to and you'll REM remember certain things about that night just when you see that picture because you drew it
also helps you a lot here's another example m76 the little dumbbell you know
everybody's style is a little different it's also hard to photograph them and and get them on you have to play with
that you can see there's a little color shift but the reason I went to digital is because I really wanna I want to take
it you know I want to go as far as I can and keep it real but you know utilizing
all the advances we've had with astrophotography and then uh you know
even just doing cell phone astronomy or or simple sketching you can combine so
many of these together and and then work a new style so this is actually the
first one I did this was actually on an envelope I was uh drawing it just a
rough with a pen a ballpoint pen you know I used to do pen paintings where I could actually shade with the pen if I
just feathered it just enough you could get it to actually shade but if you go
overboard you get ink spots and then then you're you know messed up you you just lost your midtone but this was
actually a complete tent sketch on an envelope a manila envelope Vel and I was
showing my friend and then I uploaded it inverted it and went to work and this is
what I was able to do it's the skull nebula but it doesn't look you know NGC
246 but it's it's a cool attempt and I realized that the lighting effects are
really incredible how the Stars glow and and you can create subtle tones and um
very subtle clouds and stuff this is just the first real try so you know this is another typical
sketch in the field you sketch it on I like white paper because you know it's hard to see black on white it takes a
real Keen Eye and um yeah I'm getting older now so white is easy because you
can see it in a pencil then you can upload it invert it boom that's what you can create just
from that pencil sketch you can rework it colorize it bring out the greenish
Hue that your eye sees in those planetary nebulas you know in the telescope it
looks a lot like that on a great night you see the extended arms that's why
they call it the Saturn nebula because it appears like Saturn and this is more what it would
look like as a you know refined field sketch what what people would expect to
see on cloudy nice but again it really helps you with your
um ability to see fainter objects and you trains your eye
really good what to look for and and you have to spend a lot of time doing these that's why it's such a beneficial thing
sketching them because you can really pick out details and it it makes your eye very keen and able to tease out the
finest peripheral detail that usually a lot of people miss
and then that's where you could take it this is my latest uh you know there
clouds of dust and and um blown out star matter so it's really hard to get it
perfect it's not quite a hard Edge it's almost gelatinous or like Mist you know smoky it's just
very difficult to capture the digital does give you a big Advantage allowing you to just if you don't like it go back
back or just save that and then rework start over so here's another example This was um
the Cassi nebula yeah in Draco 6543
NGC so you know this is ACC cumulated sketch this is like a lifetime of work
it's combining every sketch that I did through my meager instruments you know
even the 28 uh compared to the 60 inch is not going to give you this kind of and and some of
the nights when you get those gifted nights where the fog comes in in Pasadena blacks out everything and you
look at those planetaries then and it's dark and it's clear and and you'll never see anything quite like it it's it's
mindblowing to see the detail and that's what you can create
for a finished product you know digital allowed me to get in there and um invert
it and then soften it you know with a gloan blur you can use those in
procreate or even in um Photoshop Express they have a couple different
ones luminance um so it's like a noise cancellor so you can you know Slide the
tab it makes it softer uh you can also use a filter to soften it
but just amazing effects look at the color and and the spirographic structure inside of
that just uh very rare to see that in a in a actual
eyepiece you know it's might might be a little Beyond uh because I like to take
it as far as I can get it you know like we're actually going there because you
know the telescopes much like a time machine and when you look in that eyepiece you're going back in time and
the photons there's nothing like it I think it's it's almost like um some kind
of a rejuvenating tonic it just seems to like like when I get done observing I've been
up all night I'm still energized just on the thoughts of what I saw and how good
it's just so magical to see those in incredible views on those best nights
through the big Scopes it's nothing quite like it amazing and sharing it you know showing
others this was a Like an Eagle sketch you can see it it's pretty basic so you
can really do basic stuff you know you can also take notes of things that stood
out like well that star really had you know defraction spikes coming off of it
or you know that one side of the um nebula had this like dark which if you
invert it it's light so have to you know draw in backwards it becomes pretty easy once
you do it a few times you know then you invert it bring it in
procreate B bam look at that so now you have the Eagle Nebula
and you know this is trying to show you exactly what it looked like in the eyepiece of the big big scope with a
real good knight and a filter because in order to see that actual structure it it's very rare even
with a big scope that that really presents itself but if you're out there a lot you're really you know looking on
many nights you'll get that rare night and uh see it and when you see it for yourself I mean that's what Hubble took
a picture of The Pillars of Creation and and James web if you've seen the new
picture wow that's amazing but you know from Earth you get to see something like
that it's pretty it's almost like a spiritual moment if you can see it this
is another one the swan that I did this took quite some time uh you know I use
blending stubs HB 2B 4H pencils um magic rub
eraser to take out the you can actually shade and with the blending stub and do
your soft midtones and then erase away and and it gives some real pronounced
hard Edge you can create dust Lanes or little you know Stars whatever anything
you want and then when you invert it this is what you get of course you have to work on it it's not always
perfect so you continue to work and then you can do this bam color look at that
so that is almost like what you're going to see with uh the 32 or the 28 looking
through say a Nikon nav 17 or uh one of
the explor scientific 92 degree those those are amazing or even in ethos any
one of those three eye pieces with that filter is going to show you this kind of view in the big scope absolutely amazing
when you see it for real you just can't believe how far out the nebulosity goes
um it's a lot farther than what you normally see you know the filter really helps
too and then you know you can also create like a contest winning sketch you
never know invert it and there's
M51 so it's absolutely amazing um the effects now and this is probably a
later you know rendering so it gives you an idea of the progression but the
effects you can create like the H2 regions subtly glowing you know you just
barely pick that up and you need to look at you know the spiral arms for quite some time for those to pop
out but you can actually see them I mean that's another Island in
space you can also create beautiful flowers from your cell phone photograph
to share with your mom if she's not feeling so good you can try to brighten
her day cheer her up with a little color and just a thoughtful note you know just
thinking about you want to make sure you're doing good so here's some digital
flowers they never die you can do artistic style ones and
different looks and
dropped a couple more let me get back but I've got to go back to my thing you
know got a few more that I wanted to add to
that now I can finish this was a a tree that I walk by
every day and it was so beautiful it's a rubber tree and
these colors are pretty much what I was seeing uh different times of the year it kind of changes from a blue and a dark
and then it gets to a lighter green with the the red they turn purple the tips it's like one of the most beautiful
trees even though most rubber trees don't look that good with the color it's another one I like to uh
save to show people here's just a standard photograph you know and you can
do the levels and brighten up the colors a little to make it more effective more
wow factor and just beautiful my little buddy always comes
with me and um it allows you to you know take his picture and then put that
beautiful colored Border in there to match and create this beautiful little
Masterpiece of my best little buddy that always comes with me when I walk you
know we walk together and we always look up and see the clouds and tonight's moon was so beautiful uh with the clouds the
winds are blowing here where I live so it's really brutal with the winds I mean
the San anas but it does make a crystal blue sky and uh the clouds and the Moon
looked amazing tonight you know sometimes you have to take a picture when they're not so happy
uh he didn't like his sweater and my wife made him use
it I said it's just for a minute let's just put it on and take a picture and then when we get around the corner we'll
take it off that's what we did and then you know you take a picture
of your little buddy when you know you had such a great time doing this and a
great time we all had together but you know It's Time to Say Goodbye and uh

are your eclipse glasses safe for looking at the sun let's check to see if your e clipse glasses can handle the
heat or if they need to stay inside first off never check your
eclipse glasses with the sun that's a good way to injure your eyes take your eclipse glasses and find a bright light
like a lamp or a flashlight hold your E clips glasses up to the light and look through them the light will appear
extremely dim or not appear at all when looking through the glasses for example you should only be able to see the
filament of a light bulb but not the glow surrounding the bulb also if your eclipse glasses have any marks or
scratches on them don't use them if you have older eclipse glasses from a previous Eclipse give them the check to
make sure they haven't been damaged or scratched all safe eclipse glasses will meet the iso 1 2312 D2 standard it's
best to store eclipse glasses in a safe place where they won't become scratched or punctured remember never look at the
sun without eclipse glasses or a solar filter be safe and happy Sun viewing
