how does a planet so small and so far from the Sun have an atmosphere this is Pluto in a
[Music]
minute Pluto's orbit actually crosses Neptunes so for about two decades of
every 248 Earth year orbit Pluto makes around the sun it's inside the orbit of Neptune it turns out Neptune has a huge
effect on Pluto's orbit and the two bodies are actually in resonance with one another for every two orbits Pluto
makes around the Sun Neptune makes three and scientists think that Neptune is actually the reason Pluto is where it is
one Dynamic model of the solar system presented in the 1990s suggested that the planets actually formed closer to
the Sun than they are now it's possible under this model that Pluto formed at about 30 Au in the mid 2000s another
model was presented called the nce model that suggested that Pluto could have formed as close as 15 Au with all these
huge gas giants orbiting so closely together their gravity eventually threw this system into chaos the planet's
orbits were flung further out from the Sun and all the small bodies were also flung further out at some point Pluto
and Neptune became locked together in this resonance so the question is if Pluto formed closer to the Sun how close
was it the data from New Horizons will doubtlessly shed some light on this question but in the meantime if you want to know more about Pluto be sure to
check out the New Horizon's websites and tweet your questions using the hasht plutof flyby and of course come back
tomorrow for more Pluto in a minute

well hello everybody uh it's nice to be back I'm here with uh with David Levy
and um you're watching the 151st Global Star Party with the theme of a deeper
View and uh um it's uh it's good to be back on with you David uh it's been
several weeks um and um you know so it's always fun to put these uh these
programs together and so what is your take on the theme itself on a deeper
view well thank you thank you so much Scotty and uh welcome more I'm really
looking forward to hearing what you have to say this afternoon um my poetical contribution
today is going to be directly related to the theme of a deeper View and it begins
with a question have any of you considered why
the night sky is dark I mean we take it for granted that
the night sky is dark just like we take it for granted that ice floats if you if
you get a glass of water and you put an ice cube in it the Ice Cube will drop a
little bit down in the glass and flow back up to the surface Nobel Prize winner George wal
wrote did a beautiful program on that where he said ice floats therefore life
on Earth is possible and his reasoning was that in the very first winter when
had the little worm like creatur of early life crawling along the bottom
of the ponds and the winter would come and the layer of ice would form on the top and
then sink to the bottom eventually the pond would be and all the ponds would be
frozen solid and all the little wormlike animals would die but because ice does
not sink it floats the first layer forms and forms a protective cover for the
pond which stays a liquid allowing the little worm white creatures to stay
alive and eventually evolve to become you and me the other one is just as simple and
just as profound the night sky is dark we know that the night sky hello Adrian
we know that the night sky is is is dark we all take that for
granted but why and who is the first person that ask the question why is the
night skies dark uh um it was asked by a number of people in Greek Grecian times but I
think obviously the one who was most famous who asked the question was HRI olers from Germany the night sky is
dark it shouldn't be dark there are so many galaxies and
stars and nebula and everything else in the sky that every square inch of Sky
should be Lighting on the surface of the star therefore the night sky should be as bright as the
surface of the sun which means blindingly bright which means there is
no way life could exist on the earth that's not true the night sky is dark
and life is possible and the solution of the night
sky is dark Paradox which is commonly known now as older's
Paradox was really not finalized until just recently when with Hubble and his
expanding universe and uh the Hubble Space Telescope and the web Space Telescope
confirmed the age of the universe and the fact that a good portion of it has
not re a good portion of the light from this universe hasn't even reached us yet
which means the night sky is dark and light is possible but who is the person the
earliest person I think that really came up with the solution into that was it a
famous scientist like Edwin Hubble no they needed someone with an
imagination someone who would dream a little bit who would go out and and say a few things take a few
chances and that person was someone you are all familiar with Edgar Allen Poe
it's one of the most famous writers in English literature and certainly one of
the most famous American Writers the year before he died 1848 he
wrote an essay called Eureka in which he says he uh evaluates the uh night sky
Paradox and the surface of the Sun Paradox and he says that the reason that the sky is
dark is that the light from the farthest objects has not reached us yet and uh I mean he
wrote that in 1848 just before he died but but what I want to do now is to go
back to 1844 when he was writing the Raven which
I'm sure is a poem you are all familiar with it's one of the most famous poems in
literature he wrote it in 1844 and published in January
1845 in it he mentions the word Darkness not once because we mentioned it once
it's an AC not twice you mentioned it twice could be an accident but three times he
puts in the word darkness and of course it should be in there because it's about a raven and
it's supposed to be dark but I think that Edgar po shares the idea that I
have that darkness is not a negative thing it's a positive thing because it
relates to the fact that the night sky is dark it allows people like Scotty and
Adrian and Lori and me and all of you to look up at the night sky and enjoy it so
for my co poetical quotation today I'm going to read you three stanzas from The
Raven presently my soul grew stronger hesitating then no longer sir said I or
Madam truly your forgiveness I implore but the fact is I was napping and so
gently you came wrapping and so faintly you came tapping tapping at my chamber door that I scarce Was Heard sure I
heard you here I opened wide the door Darkness there and nothing more deep into that Darkness peering
long I stood there wondering fearing doubting Dreaming Dreams no mortal ever dared to dream before but the silence
was unbroken and the Darkness gave no token and the only word there spoken was that whispered word Lenor this I
whispered in an echo murmured back the word Lenor near L this and nothing more
and at this point I'm going to interrupt my own reading to say that there is a modernday
relationship to the Raven uh when shean and Carolyn were alive and they were living in
Flagstaff two Ravens kind of adopted Gan and Carolin and they came in and they
started eating the food and of course Carolyn and Jean would be feeding them a little bit so they would stay and they
did and what do you know they named those two birds never and more and there as far as I know those
birds are still there enjoying the home that she and caring gave them so long and now the
last of the three verses then this ebony bird beguiling I said fancy into smiling by the grave and
Stern decorum of the countenance it wor though thy Crest be shorn and shaven
thou I said art sure no Craven Gastly Grim an ancient Raven wandering from the
nightly Shore tell me what thy lordly name is on the nights plutonian Shore
both the Raven never more thank you very much hope you enjoyed that little thing
back to SC that was very good that was very good thank you well we have uh we
have a nice group of people watching live um uh let me uh get some of the
names here we've got Mike weasner I know there's people uh out there watching that don't chat but uh thank you for
tuning in anyways um Pekka Halala from Stockholm is tuning in uh sadly from uh
the hospital but uh we're hoping that you get better soon Pekka um uh John Ray is uh watching here
on Facebook and we've got uh Paul bergart um watching on YouTube and Tina
D duanes hopefully I got got that correct Tina sorry if I messed that up
um and um uh I think I already mentioned John Ray but uh but anyhow uh thank you
all for tuning in to our 151st Global Star Party um uh coming up next here uh
we have uh uh Lori and sge and she is um
with um uh the State astronomers with the
astronomical League um with the Girl Scouts and with many organizations that
have to do with astronomy here so um so before you start sharing there
Lori I'll uh I'll give a little a little uh intro here for
you so here we go and
[Music]
I did all that hard work to make that so I had to show it so let's bring you on Lori thank you
for coming on to the 151st Global star party this is your second time to be on
representing the astronomical league and um I like the background there the books
the uh the uh the astronomical images it looks like there's a star map back there
got your league shirt on it's awesome we're go we're all going to be at the
astronomical uh League conference the Alcon event that's going to be in Kansas City Missouri coming up here this July
and uh so I'll let you take that away Lori and um uh you know I know that you
have also your topic uh that you're going to um be talking about here but uh
our theme is a deeper view so take a great what a great theme too and just a
plug for the league in the background is also my um U pins that I'm amassing from
the observing programs that I uh certainly can't speak enough of or
about so I am going to share a screen
yeah they have so many observing programs I think it's over 80 observing
programs it's a lot and then there's also a lot of um got to get this back to
the beginning um there's also a lot of observing challenges which if folks aren't
familiar with them uh they need to take a look at those they're usually short
and sweet and a lot of times there's two levels and they're very achievable the really cool thing about the observing
challenges is that you can get your toe dipped into other challenges by doing a
challenge I tipped my my dip I dipped my toe into the Glock ular cluster
observing challenge two years ago and then took a look at the rest of the program and was feeling like I could do
it and so I did and so that's pretty cool so um with the deeper view I
thought that was a really great theme I uh took this to a little bit of a level
um I like fairy tales so I'm going to start off with Once Upon a Time and I'm figuring that this is something that
doid might appreciate too with his immense background in literary stuff so
once upon a time um I started enjoying the night sky I don't know when or how
but I did and I remember that uh in college as a photo student I was taking
pictures of star trails that U ended up in some of the The Works that I had to
do um and I think this uh page might be one of the few things that um survived
that but I yearned for a deeper view I became a trained photographer ran
commercial Photo Labs Serendipity uh to cold and it was uh
great because during that time we had Comet hiy uh the first comet that I've ever observed and in order to get that
this is a reprint here in the middle from astronomy Magazine from
1986 I had to go out with my Canon ae1 and I um
had to go out with this pushpull film that was pretty new at the time I had
the laboratory to myself and so I had that slide film running at the slowest
speed that any film had ever gone through that processor ever it took me
six tries going out there and shooting on different nights and for those of us that might remember Comet hle it was
dubbed a disappointment because it was so dim um in fact I could not see it with my
naked eye or the lenses that I had the only way I could see it was taking my
slide film and putting my loop on it on a light table and comparing it to star charts and that little tiny thing that
you see there maybe because it is very tiny on the screen is just a little bit
off the angle of the rest of the star trails and exactly where it needed to
be but my Canon A1 wasn't enough I still yearned for a deeper view fast forward
in life a little bit and we acquired an 8in Newtonian German equatorial mount
scope secondhand and I didn't know anything about the astronomical League or clubs
but I started a journal anyway my idea of the journal was to write what I saw
but it was still a little bit on unsatisfactory because I was going to the internet and downloading NASA images
or whatever I could find that could kind of give me a sense of what I'd seen so I
cut them out I pasted them into my log and I didn't worry nobody was ever going
to see this this was for me for a photographer and I'm sure that Adrien
later will be able to speak to this too it's rather unsatisfactory
well fast forward I'm still working full-time at this point in my life raising two kids and I've moved up in
the world from cut and paste to a little Canon point and shoot and with it have
discovered the paint program that comes free on your computers and with that I got to comment
neowise I've gotten a couple other comets like love joy and whatnot in the
meantime and I also got the ISS with my cell phone uh while finding Al debron
Venus and pleades in the neighborhood but still when you're looking at these
fabulous images out there and knowing that there's more to see and star hopping is so hard in a
light polluted area with your 8 inch equatorial Mount um U telescope I still
yearned for that deeper view then in March
2022 there was a lifechanging event to my club came somebody who had gotten an
EV scope too now this isn't for everybody and
it's not Adrien Bradley's level of astrophotography but I just will enjoy
his stuff and what he does and I love hearing him speak and others this was
was my thing I could finally see what it was that I was looking at in a way that
I could comprehend it and understand it so in the left corner here I have um
five different shots taken of the C 2017 K2 pan Stars Comet by the way I did
sense them with this scope get the silver level Comet uh award in the
program and I'm working towards my my gold we need some more comets folks so I'll hail the solar system send them our
way and I did get that silver level in in June of last year and I also worked
on those tiny globular clusters and got that one in September of 22 so the
unistellar became exactly that niche of what it was that I
needed so in my fairy tale I've gone from my downloaded images from the
internet into my little hands scribed um notes to now
spreadsheets and file paths for where I've got my images stored and notes that
I can then upload and put in for astronomical League uh observing
programs and sometimes the programs will even let you take an observation from
one and use it for another which is kind of Handy and sometimes I just want to go
see it again because Sky conditions weren't all that great but I was able to
finally get my deeper view but wait there's
more so um if you look at the left here
this is sort of a time lapse of what it is that we get to see
and many of the folks that we also um do the the Outreach with get to see over
time I'll have them come over look in the eyepiece and then I'll have them come back over and look at the eyepiece
because this marvelous telescope stacks these images in real time what does that
mean it keeps taking these pictures one every four seconds and it glues them together automagically those electrons
coming together uh taking these photons and and doing their work so that at the
end of the exposure you've got this ready-made picture that's not beautiful
Hubble level stuff but I can tell that the pin wheel Galaxy is a Galaxy and
it's a spiral which is all I wanted from my scope still like my fuzzy blobs but
this is for me and then on the right we've got the solar the um solar eclipse
again from April down in the explore scientific Expedition uh that um this this really
knocked my socks off and I mentioned this last time I was on because I'm looking at those solar flares and I had
no idea my little scope would do that but I am tickled to death with it and if
anybody wants to know the easy.com is a real easy place to take your multiple
images and put them together to have this um instant free little video that
happens so with all of that I get to enjoy my deeper view while under the
stars and not spending hours in front of my computer but I retired as a it
supervisor so I don't want to spend hours behind my computer in my retirement I want to enjoy my dark skies
and I'm very happy looking at other people's computer processing we had one speaker at our last club meeting who
said that uh I asked him how many hours did you spend doing that postprocessing
on that image that image not plural and his response was somewhere between 40
and 50 hours wow I've got too many hobbies and
I like to quilt amongst other things and garden and
socialize um but anyway I've basically decided that in my journey for a deeper
view that what they call Electronic assisted astronomy or EAA is for me
that's my Niche so on the far left here because of that electronic assisted
astronomy I'm able to see the sunspots and the granulation of what's happening
with a solar filter of for white light on there and I can blow it up on my
computer screen if I want to see more that's actually wet my appetite for H
Alpha solar viewing and so I'm I'm looking at that now too in the middle
there you've got the uh flame nebula and these aren't particularly long exposures
but I can tell it's a flame nebula and I can enjoy others who've put all of the
time into the computer processing to see their flame nebulas but this is a little
snapshot in time of my experience that night with the flame nebula and on the
right thanks to the uh extra efforts on the app developers at
unistellar um I've got a pretty decent image of the Moon that if I had this
capability in that app version at the time maybe I could have used that for one of the lunar challenges or the lunar
program before but I think it's good enough you can use it now um so I'm looking forward to that
so in my fairy tale we are Liv living happily ever after with our equipment in
the bottom center is my dear husband who is uh I guess we're unicorns it doesn't
seem like this hobby has many um married couples that are into it that um enjoy
going out there and observing and the equipment and all that stuff and we've got our own little division of labor if
there's post-processing he'll actually take it up and I've met these wonderful people along the way like doid there in
the lower left corner and um Minard who's the executive secretary for the
astronomical League um my cats of course are interested in the equipment as you
can see and uh of course we're very involved in our club uh as you can see
from the work on the Dome so that's my uh deeper view into
the universe and and how I like to enjoy it and as I am working with the
astronomical league and um blessed to be here I uh just want to remind everybody
that July 17th through 20th so we're a month out we're going to Kansas City and
we're going to Alcon the astronomic league convention it'll be at the Double
Tree by H don't know when the cut off deadlines are but I do know that doid is
his his talk has now been sold out and uh we're looking forward to hearing from
them and there's uh quite a bit of um of speakers that they have firmed up and I
just recently looked at the uh lineup again and it's filling in very nicely
it's always a great time you get to meet new people that you get to talk to again
um and then I have one more plug and that is uh before we get to
questions U let me stop my share and pull this up we have the
astronomical um let's see we have a astronomical
Festival down on the mall in DC coming up this Saturday so if anybody wants to
beat the heat H hastra University right that is correct and and I hopefully or
have got this up on the screen now uh it's down on the mall it's uh
outside of the hershorn sculpture garden which is uh towards the capital end uh
runs from 6 to 11 that means we'll have solar and we will have uh nighttime
viewing I will have a unistellar out there so that very light polluted Sky
won't be disappointing you will be able to see things as long as there aren't thi clouds in
there and so I'll stop there and ask if there are questions from
anybody uh well no questions but uh uh lots of Praise uh for the presentation I
really enjoyed it and um couple things I was jealous because in your chart you
had a globular cluster known as 47 tucane I've seen Omega centori but I
have not seen 47 sucan I have to actually go to the southern hemisphere for that so that's something I'm hoping
to do in the next uh years of Lifetime to save for and um I love the fact that
uh EAA is something that you Embrace that's actually what I did when I started in
astronomy and it was the path that got me into doing Widefield astop
photography landscape it's had so many names came from wanting to do something
with photography graphy and wanting to combine that with astronomy and not be
beholden to Cloudy Skies or even the same place and lugging around a bunch of
equipment that's it and it grew into what I you know what I'm doing today so
um no hats off to the way that you attack um your uh passion for the night
sky and it's uh it's definitely something uh those EV Scopes and there
was something else that I used called the revolution imager and the EV scope is the uh much better and easier package
that takes up where that started so uh no that's awesome and I will be in
attendance at uh Alcon so I look forward to meeting you and everyone who's there
I'm hoping you'll sign my um my magazine with your layout in it uh I'm planning
on bringing it when I see you there and um I'll just absolutely a plug to say we
still use the revolution ipce nice it's still a nice thing to use um even with
the solar with a a bit of a a tent outside for kids to to see it better and
also to make it more accessible to the scope for folks so we're very into the
Outreach thing um I'll just say that I've gone a little bit further with
unistellar right before the annular Eclipse they um accepted me in their beta test program oh cool so um I've had
a chance to help give them the feedback to help make that product better so that I could have a better
product everybody wins that's that's how it usually works but uh yeah awesome I
look forward to uh just being there sure I'll sign I'll sign anyone's uh magazine
if it's there um we'll enjoy and enjoy the uh programming there too so uh oh
that's awesome look forward I look forward to it thank you very good one of the things that I would like to had is
um your take on the uh deeper view theme of this week I mean whether it is a
philosophical deeper view or whether it is a deeper View using more Advanced
Equipment as you did or whether it is a deeper view just looking up a little
more deeply and thinking about it I think your presentation really really
added to the theme of this week's star party I just Lov it wor thank you very
much you that means so much to
me wonderful wonderful okay all right so um uh we are
going to uh move on to the next section here um uh we I've have thrown in a few
vide short videos from NASA um uh that uh hopefully kind of go along with the
theme as well but uh you know and I look at all the work that goes into those that programming that NASA and the
European Space Agency put forward uh we're really really uh fortunate to live
in these times you know um the visualizations and stuff that they do
are just amazing and um so I think you'll agree uh this one is uh from the
Hubble Space Telescope
this is an image of a lensing galaxy cluster called Max 1149 and this
particular Galaxy cluster is very interesting because it is a lens for a
gravitationally lensed supernova this Supernova was nicknamed Supernova refall so you can actually see this cool spiral
galaxy that looks kind of like it's melting it almost looks like a little bit like a Salvador D painting of a galaxy this is actually a
gravitationally lensed background Galaxy that you're seeing multiple images of and you can see some of these little
dots here are a supernova that has gone off in this background Galaxy and then been gravitationally lensed so we can
see multiple images of it so we can actually see the same Supernova going off multiple times in this image which
makes it particularly cool to see these four dots are appearing in a pattern called an Einstein
cross closer to the center of this massive Galaxy this brightest fuzzy
yellow object here would be the very center of the the Galaxy CL cluster this is where most of the mass is going to be
this is why you get the the strongest distortions from gravitational lensing here you can sort of see this this third
image of the Galaxy that's really stretched out you can sort of barely see it behind this brightest cluster Galaxy
gravitational lensing Works where the Galaxy cluster or any other massive object bends the space around it with a
massive object like this galaxy cluster in outer space it deforms the space around it and then as light travels
through that deformed warped space the light bends just like looking through a Glass
Lens this is another view of this lensing galaxy cluster along with a zoom
in of the lens Supernova you can see here this is the image that we were looking at previously along with a few
extra details added so this is our cute little Hubble Space Telescope down here not perfectly to scale and then you have
an image of what the background Galaxy would look like back here and these white lines are kind of tracing where
the light from this background Galaxy would travel through the Galaxy cluster it acts as a lens it actually bends the
light rays back towards each other and back towards our telescope here then if we look at this zoomed in version down
here you have these four yellow Points of Light here which are all images of
the same gravitationally lensed Supernova a ref stall so this Supernova would have originated somewhere in this
galaxy and then the light from it would travel along these different paths around this lens eventually meeting back
up at our Hubble Space Telescope and what's really awesome about this is that by measuring the different time that it
takes for the light to travel from its source to our telescope through these different paths around the gravitational
lens we can get a really strong constraint of exactly how far away the Supernova is and therefore a really
strong constraint of how quickly the universe is expanding this is an incredibly exciting image
gravitationally lensed Supernova like the one that we're seeing in this image is sort of a a one-of-a-kind object it
really gives us a very unique look at how these Supernova can interact with a
gravitational lens which gives us a ton of additional information on both the Dark Matter within the gravitational
lens itself and a good amount of information on how the universe is expanding so this is kind of an open
question that we're still battling with as astronomers is exactly how quickly the universe is expanding one of the
cool things about these gravitationally lens supern noi is that once you see one of it you can predict when the other
images are going to show that same
Supernova this Einstein cross here was the first image of the Supernova that was observed but we were able to predict
that the other images of the Galaxy one of them would have shown up about 20 years prior and then they were able to
predict that actually this image over here the lens Supernova was going to appear in this image about a year after
this first one was discovered so astronomers were then able to go back with the Hubble Space Telescope and observe it about when they predicted the
second image to show up and they were actually able to find it a year later which was a a really cool confirmation
of the predictions we were able to actually predict where it was going to be and then it showed up so it sort of very clearly shows that our models are
working very well this is a unique way of measuring that expansion using these
gravitationally lensed supern noi and this particular example is one of the best that we have so this is a really
incredible opportunity to to study a whole lot of different uh components of the universe
[Music]
okay our next speaker let me get rid of my echo here although does sound kind of
cool anyways our next speaker is uh Ron breacher and uh Ron is a master
astrophotographer um and he is uh he gives online uh tutorials on how to use
uh pix Insight which is a very Advanced image and very powerful image processing
program uh but uh uh Ron uh uh includes
me in his distribution of uh his pictures of the week and they are just
mindblowing um and so um Ron I want to
thank you for coming on to the 151st Global star party and yeah so excellent
so what are you covering uh for us today it was uh the topic is photons to phot
phot yeah I you know I always try to tie into your theme a deeper View and um you
know I show a lot of my Astro photos but I don't really talk too much about how
they're made and of course it all starts with capturing photons with your telescope or
your your lens and then recording those photons on some kind of sensor whether
it's film or in the old days or or uh now on digital media so I thought it
would be fun to just share with you how that's done but in Fairly plain language I'm not going to open an image
processing program and I'm not going to pull any bells you know pull pull any levers or push any buttons um I just
want to talk about the the process and give you an appreciation of what it takes to catch photons in the first
place they're like butterflies you know you got to catch them first and then make them make them really look
beautiful so uh let me let me share my screen with you and I'll just start the
slideshow so um by the way I'm sorry I couldn't be at the
150th I was giving I was uh giving another presentation so I thought that
was a really important Milestone and I wanted to congratulate you on that thanks thank you um so I want to just
sort of put my presentation in the context of tonight's theme and then I'm going to show you how to take photons to
photos in six easy step steps and I say that tongue firmly in cheek and I'm
going to just sort of walk you through an example one example so uh in terms of the deeper
view uh Scott talked about the Revolutionary observational power of modern telescopes
and uh he he noted the James web Space Telescope but I I think it's also not
worthy how many amateurs are using incredible telescopes right in their own
backyard and uh we're all on this quest to gaze deeper into space and time and
unravel the mysteries of the universe's earliest galaxies and again uh even with
amateur equipment from your backyard you can see some of the earliest galaxies so
um let's let's have a look so the first thing you have to do is acquire the data
and uh what you're looking at here believe it or not is a single 20 minute exposure in hydrogen Alpha on the
California nebula doesn't look like much does
it um that's because the sky is dark at
night most of the pixels are almost black
they're not quite black but they're almost black and in fact I'm going to
later on I'm going to take those nearly black pixels and I'm going to make them
brighter without letting the stars get too bright you can see a couple of
bright stars like this one here yeah so here's here's what we're
we're kind of looking at so we have to acquire the data this is a single 20 minute exposure but you can see it's
really noisy I've made the data visible really it looked like
this but I've made some of those nearly black pixels visible and you can see
there's a lot of noise in there and uh all kinds of other junk too so you can
see for example the corners are dark if you look in this picture if you look up close there's some up and down vertical
lines in the data too overall really nasty that's because we're taking we're
using our cameras in extremely difficult conditions for the camera low light low light low
contrast so we have to take out all this junk there's uh at the lower left dark
signal that's accounting for all the speckling there's bias signal which is accounting for some of those vertical
lines that you can see and then uh the darkening in the corners and any dust
spots you might see is due to imperfections in your Optics dust on the filter for example
but when you when you clean up a raw frame like
this and you combine align them and combine them a whole bunch of them this
is what you get oh nice so this is a single 20 minute
frame this is 25 20 minute frames that have been properly
calibrated so the corners are nice and bright those little dark uh bright Speckles they're all gone and this is
now a nice stock for one filter but of course we have to with my camera it's a
black and white camera so I have to repeat as needed for every filter depending on what I'm trying to trying
to shoot so that might just be natural red green blue or it might be the Hub
pallet sulfur hydrogen and oxygen emissions or maybe I'll shoot Hubble
pallet and add some natural color stars and for the image I'm going to show you
in a moment I added hydrogen Alpha to the natural color Galaxy and you can
also do just narrow band Hydro and oxygen so then you got to process the
image if you've got a mono camera like I do you got to make a color image then you do the linear processing so what
does linear mean a file is linear when there's a relationship between the
number of photons that hit the sensor and how bright a pixel
is so if you get one Photon hitting a pixel
and next to it 100 photons hitting that pixel the the readings should be 100
fold different so that's a nice linear relationship and when when that
relationship exists while the picture is really dark you can take out gradients
of color you can do color correction you can remove any blurring you can remove
noise after that's done then we do the artistic steps so we make the image more
like a daytime image so we brighten everything sharpen it adjust the color brightness and contrast so let's walk
that through uh through let me walk you through that with an example so this is
going to be Messier 108 this is just a a single unstretched
image but this is what's really there so here I combined the three red
green and blue images and I put a temporary stretch on for you to see I do
want to highlight that there's all kinds of problems here um I don't know if you can see this satellite
trail that goes I'm going to just there's a green satellite Trail
there and uh I highlighted some dust spots these are shadows of dust spots
that I'm going to have to take care of but on the other hand look at all the tiny little galaxies
here they're everywhere in this field yeah so this is going to be
fun so I took the stars out and did some processing added the hydrogen Alpha into
it and then I stretched it and so now what I did is I've made it permanently
like this not just temporary uh I've brightened the Galaxy
but left the background nice and dark and I took the stars out and worked
on them separately but then I put them
back and this is the final image really pretty and here you have Messier 108
this is easily visible through a small telescope even a even a four or 6 in
telescope will give you a great view of this it's well placed right now in the northern hemisphere
it's uh fairly high up in the Northwestern Sky uh shortly after dark
you won't see it like this it'll just look like a smudge like the head of a
cutp but it's beautiful and the fact is you're seeing something that's 28
million light years away and you won't see these but all
these other little galaxies this one here this one up here down
here this little guy over here this one here there's another one
here more down here several of them over here all of those galaxies are far far
in the background so there are hundreds of millions of light years away now this is
step five processing the image the really is a step
5A and that is sending it to one friend in five or 10 different versions because
you can't make up your mind of which you like the best but uh eventually step
five is over and we move to step six and step six is to get blown away basically
I run an annotation program at the end of every
process and and uh all the yellow annotations here the the numbers at
least are uh they're all galaxies but all the white annotations
are quazars from very very early in our galaxy and this is what Scott was
talking about when he referred to looking deep back into the early days of
the universe and I want to highlight for you the two bold circles at lower right
in this image those are two quazars and they're 9.3 billion light
years away this top one and I think you can see in the crosshairs it's clearly
visible yes from my backyard 9.3 billion years of light
travel time and this one is even more impressive and also clearly visible and
almost 13 billion light years away so
you know the James web is amazing I'm not trying to compete with
it I'm just blown away that I can see so far into the distant
past and uh that's what I wanted to show you today if anybody's interested in uh
getting in touch with me you can find me at Astro doca or R breacher rogers.com RB C ER
rogers.com and uh look for my articles in sky and Telescope this is the telescope that I
shot M m108 with it's a 14inch Celestron
Edge HD with a qhy600 mono camera I used all
opong filters and also a q Hy off AIS sker Primal luche Eagle controlling the
run and a primal luche focuser Rotator this is a really beautiful
Paramount MX Mount which I've had since I think 2013 so 11 12 years and running like a
champ and you can tell I'm looking very happy in this picture it was a good day
yeah it's a beautiful rig and wonderful uh Observatory that you got there too oh
yeah it's like the best man cave ever I'm telling you I love it okay let me
stop my share wonderful wonderful thank you as always for having me on I love doing
this yeah we we love having you on so uh uh so what what uh David what did you
think of it of Ron's images
you're m m you're mute unmuted I just to say that each
time we get a lecture tonight it gives us a different
parameter on uh the depth of the night sky we have one from Lori one from Edgar
Poe and one from you and uh all very different all extremely valid and all
just wonderful thank you just wonderful you know the Canadians have renamed the
James Webb Telescope they left the initials jwst but they call it the just
wonderful Space Telescope well uh Ron I was impressed
with the uh rig that you had there are two things that really stuck out I've
you know I've gone into the Widefield because carrying 14 a 14inch scope in a
rig like that to be under the stars just just wasn't going to work I traded my
truck in so the little vehicle I got now just doesn't work but you made a very
very Salient point I'm not just GNA say good uh you showed those quazars in your
image and the fact that with with your gear to me the real value of knowing
your gear is now you've got a lot more Universe than those who f
solely on their one image there's a lot more there and um it's worth it to look
at well what else did you get besides your main image and um it it really uh
it deepens you we're talking about a deeper view you know you're right that is a that's a deeper view right there
you're seeing a lot more out of your image than just the main you know you're
not it the focus on that one image is one thing but to realize just how much
of a slice of universe you've got you know you every time you fire that thing up you're you're traveling through time
further back in time than you may think so every time every time I point that
thing in the direction of a bright Galaxy there's a hundred faint ones behind it yeah you know absolutely
amateur astronomers are so fort especially in this we're in this golden
age of astronomy and uh you know at what other time where amateur astronomers
doing this kind of work from their backyard oh yeah the answer is never you know so it's really it's really
wonderful so and uh there is one thing I want to add to what you just said and to
what Ron just said that whenever you point your telescope at a bright Galaxy there are many faint ones right behind
it and faint ones behind each of those faint ones and fainter on behind each of those ones but as you go deeper and
deeper you still don't get over the fact that despite all of this there is still
only one run run in the in the universe
only one Scotty Roberts only one Adrien only one Cesar and even only one D yes
and I just wanted to add that little extra yeah amazing well don't forget one
Lori she you wouldn't want more than let's
not forget our audience here already very cool very sorry Laura yeah
only one of you too y wonderful okay see
you later you guys thank you so much Ron thank you hi uh David we are uh going to
watch another another uh really cool um NASA video and this has to do with u one
of my favorite objects and I think one of yours too uh this is the horsee head nebula so let's let's check that out
it's just a few minutes and I think it's uh an excellent um uh visualization
[Music]
[Music]
just before we get on to Adrian uh I just want to mention that even though
the horse head is extremely easy to photograph it is almost impossible to
see I've seen it and uh it really is tough you need a very dark sky and a
little bit of averted imagination to see but it's it's there but it photographs
extremely easily yeah de I've seen it someone put
a filter on to make it a little easier first we saw Thor's helmet then he
pointed that 18 was it an 18inch obsession I think uh large scope pointed
it at um the horse head nebula and I took a look at that and crossed
something off of the bucket list because uh as much as you can even get the horse
head with a 35 millimeter lens on a regular camera but to see it with your
own eyes is something something magical and uh we were there at okek with
somebody who had the uh right equipment to do it and that goes down in one of as
one of my most uh enjoyable moments at okite Teek both of my two most enjoyable
moments actually have to do with Orion and so um that was one of them the other
one seeing the zedal light cross the Ryan spur with Orion sitting over there
um about 300 or 4 in the morning um I was actually trying to rush to a porta
poot and I looked up at that sky and that was the first time I'd seen the
that whole Winter Circle the Orion area in that sky and it stopped everything I
uh I didn't even have to worry about the portapotty because nothing moved for and
I'm telling you the truth I did not have to use the bathroom for about a minute just looking it's like my body forgot
that it was rushing to get somewhere and then it began to as everything began to
wake up and I said I got to get samples of this then everything started to turn on again I made it safely to the
portapotty got my equipment and the images that I've tried to take of this
have not done Justice to what I saw with my own eyes that it's a Memory I'll
never never forget that's that memory even beats seeing the core of the Galaxy
come out at me during nautical twilight it that and seeing the horse head uh you
know with my eyes beats both of you know beats all of my core memories I guess
the the core coming out and being that bright was number three but uh yeah it
has to take third place compared to those two views excellent so uh
and unfortunately my presentation de and Scott probably won't have any uh oryan
in it but um it it will have uh some of the techniques that you saw
Ron talk about can actually come into play when you're doing um night sky
photography with your own camera um Scott I can go ahead and start if you
yeah let's do that go ahead all right well first before I start I want to get my screen
going and then see if I can share my
screen let's just share the whole screen all right so you can see the view
of the presentation that I don't want you to see and now you're seeing the view the
presentation that I do want you to see chasing Dark Skies a deeper view
with a few images and a familiar poem um one thing that I'll you know I
like to use these images that I self images of me looking up at these uh at
these night sky things I you know we're in a world where you have a lot of us
that come from the photography side and we're used to taking images we're used to presenting
them and we're used to in these days social media we post them we get some
likes loves we generally don't say a lot about the images we let the images speak
for themselves in the world of astronomy is where I found a home because I like
to talk about exactly what we're seeing exactly what is this little thing and this little thing next to it and what
are these clusters and marks and what's all of this about you know the year that
I'm recreating looking at the uh Milky Way I didn't see all of this detail well
all I saw looked like a little bit of steam coming out of sagittarius's uh the
teapot asterism for Sagittarius and then later as I learned
Light Pillars Aurora that can come close enough to where this is a live shot the
camera processing is one thing but these are the actual colors I saw with my eyes um you know the night sky is a uh
wonderful thing to just enjoy and not just take your images from for whatever
you know whatever game that you want to do so I'm going to discuss we're going
to get deeper into captur Ing nightscapes and the Darkness
level um I use an sqml meter because we've all heard of bortle Skies we um
you know there there's a lot of uh this is a bort 3 sky this is a bort 2 sky
this is a bort four sky and when I put the meter up um sometimes the meter
tells you what you're dealing with right now the sky isn't always at that same
level um but depending on the darkness of the sky it affects how some of these
uh techniques like single frames taking a single frame untracked of your nightscape which you
know in all intensive purposes includes Milky Way Photography um you can stack those short
exposures to try and get more detail you can take a single long exposure you can
stack those longer exposures you can stack tract exposures and even do focus
stacking for the ground this level right now we're just doing we're here this is where I'm at and this is
what I would like to experiment with but when you get to this level you start to
create images that you're combining the night sky with something in the
foreground and you're creating these beautiful landscape sometimes you look
at him and go is this something I would actually see in the natural world so I use the natural world as sort of my
guide it's something that I would go see if I went there like this picture this
is what you would have seen if you were with me you'd have seen my buddy processing his Astro photo you would
have seen this um this thing here the Aurora behind it and the trees and this
faint wisp of the uh pereus copia and um
the signis part of the Milky Way as it was rising and so we'll start with what a
short exposure looks like and the background I use is an example of it I
went out and took a few Milky Way images uh Galactic core images which are very
popular amongst the Milky Way Shooters it is one of the brightest areas in the
Milky Way um most may say it's the brightest but um there was a lot of
ground fog so you have this 30 second image that captures exactly what was
going on I did crop it um off of 24 millimeter and you get a snapshot of
what's in the sky we've got a lot of Sky glow out there and a lot of a lot of us that are doing Imaging are finding out
that uh there's a lot of Sky glow and there's some you know what does that mean what are we seeing but um a good
part of that is due to the fact that we're in a solar maximum period we're
we're approaching um solar maximum so a more active Sun blasts more radiation towards
Earth and at night those uh reactions are still happening with um
oxygen nitrogen and causing the colors green is seen here in this park uh there
will be some images where you'll see some of the red some a slightly darker sky and also with a um you know with a
um ha modified camera you see green you see red so air glow if there were Aurora
you'd catch it but you also get your satellites airplanes and your chance meteors
and the light pollution from nearby cities and towns is much more
pronounced so the single shots um really fast lenses you know
your ISO or gain up a little bit you can get a sense for what's out there in the
sky and what you can capture now if you decide to do a stack
of it all of a sudden your detail in your deep space object objects like the
catspaw that shows up here um I call it a challenge object for for all this
Milky Way Shooters how much detail can we get M77
M16 small star Cloud M23 M24
M22 M8 M20 the triffid even shows up here with
38 stacked images Ruki appears
you've seen beautiful images of this region you won't quite see that much
detail in my shots because they're all a part of this wide angle Messi
A4 um globular cluster shows up there's another smaller globular cluster here
probably not visible these objects in the night sky that I just mentioned show
up and for me I like knowing that that's there because when I do my Milky Way
Photography I'm not just sticking this thing in front of something that's beautiful to see in the foreground I
want the detail there um because that lets me know if I've got the type of
detail that I like in the night sky and stacking your images and using something like Starry landscape stacker can help
achieve that detail now here you've got a regular dark Sky park with someone
doing some Imaging I forget he was going after the uh there's by the North Star
there's um this sort of you know Intergalactic flux flux that's around po
if when it's captured beautifully you know it's something to look at but he's
he's attempting to capture frames over there and I'm capturing him and everything else in a single
shot so there's equipment to buy like a tracker for what you're going to see
next but doing this 10 seconds each take a number of
exposures you can freeze your camera you don't have to track and it helps you get
into getting a little more detail with your night sky and you can
you know improve you can take more um Sky Images if you want to try
and get even more detail without a Tracker but keep in mind if you're setting up a scene the difference
between regular deep Sky uh DSO astrophotography and wide scape is this
scene is going to change and at some point this part of the Milky Way is going to be over here if you want a
single image you have a limited amount of time to capture uh the data you're
going to capture and so we go longer
exposure and this is where the longer exposures you're pulling in more data
now you're seeing all the dust Lanes here more you're seeing more dust Lanes
now somehow the uh the cats paaw disappeared here so not as happy with
the image but you see more dust Lanes you see more detail you're taking your longer exposures and that's the sort of
thing that requires a Tracker um so you have a night sky that
doesn't you it's not as dark your Milky Way Photography or just whatever you're
looking at in the night sky doesn't come out quite as good but you can um if you
love having the Milky Way in all its Glory no matter where you are you can take longer exposures and stack those
and it will begin to show some of the detail of the Milky Way that you are is
normally reserved for taking images at darker sky in Darker Skies so if you do
go ahead and invest in a Tracker consider taking stacks of longer exposures and learning how to do your
composits not you see some of this around the tree that's some of the uh
cleanup that didn't happen when I went to combine the single shot
for the land here and the shot with the night sky the better you get at composits the more these um these sort
of uh techniques you can use and this is the same place with a
longer tracker um something that was able to achieve five minutes
and our cat's paws back here we go through the uh lettering the cats paws
back here butterflies here tm's cluster right in between this you you see some
of the detail of the dark nebula it's really the dark nebula that bring out
parts of our galaxy any part of the Milky Way that we can see getting good
Imaging of this dark nebula good contrast of the dark nebula brings all
of that out and the rest of what you've got here with um Scorpius next to it
those of you who are in the southern hemisphere everything below Horizon is
yours to image your Southern Cross is down there uh when Orion is in the sky
in the same spot you all have the melenic clouds you have the Ada caran region you've got um where the southern
crosses you've got that whole Southern the southern bulge you've got a lot more
to play with over there we have the signis region and I think for a brief
moment you get to see the signis region and anything North like the copia region
but that then that doesn't stay in your Sky very long going to a darker sky this is a
shorter exposure and here's some things to look out for um there's noise
reduction tools that can take take care of the grainy result but they can also
because you're combining land with Sky your land ends up being more painterly
or you know just uh it gets blurry um thanks to the noise reduction tool that
you use so you have to use your you know pick and choose your noise reduction you're always better off um getting as
good and exposure as you can if you're somewhere darker this is 20 1.1 on an sqm mimer it's roughly High bort for um
if you get to 21.6 you're you're supposedly portal three you kind of get
an idea of how dark that sky is um so take excuse me taking a single
image here you've got the uh cassop pipar of the Milky Way this is Aurora
down here and it's kind of blending in with the sky glow that Sky glow there's
a little bit of reddish Sky glow and it's actually been bending into the Aurora top right
here there was some faint Aurora on the in the
distance and now five minutes and combining here's
the effect I was talking about this didn't go so well it looks like it's blurred
fuzzy didn't quite work the way I would have wanted to but the sky absolutely
did look at Andromeda here you've got more data from Andromeda by Imaging for
five minutes m33 is down below The Water
Somewhere it would have been nice if I had waited long enough to see how that
would have looked with a longer exposure so that's that's something I'll be able to try sometime
soon uh Gary Palmer who's been on the show before the longer you uh image the
longer exposure you take the more data you get all right so now let's uh let's uh
run to the end here now I like the way this large lake this is a lake hon it's
a large sea one of the Great Lakes um a longer ground image and you've got a
image and you've got a lot of light pollution Port hon really is this bright
over here under these clouds is Canada and this
was four times a two-minute exposure for the sky pretty good medium for showing
everything that was out there your gravity waves from the
um uh what is it the air glow when you see lines like that you get gravity
waves or at least that's what they're called you can see them a little better here this was the five minute
exposure it was easier to clean the Milky Way image up here I paired it with
a shorter exposure for the ground and got some of this modeling so obviously
the previous uh view of the sea paired with this image would make a good final image
and then this was a stacking attempt gone wrong so I just left the whole thing in I went five times five minutes
over in this region to see what would happen um with these settings
and Haze overcame and it just it turned into a mess so if you go to stack and it
doesn't work out then you can have you end up with
with this uh throwaway stack but it was one of those frames I used in a previous
image and so this is important use whichever
method produces the results you're looking for and also use the method that
you're comfortable with if you are not as comfortable being out here in because
it's dark in some of these places if you're not very comfortable use a
shorter method to capture you know the Milky Way and if you're just looking for
the plane of the Galaxy to be in an image um start with that um definitely
learn the number of things that you can do and there are photography tricks a
lot of people use light painting blue hour Imaging where they'll come take a
nice sharp picture of the uh foreground as the sun goes
down then take a picture of the sky sometimes in the same area sometimes
it's a picture of the sky they've moved it they'll combine the two my goal is to
take those images minutes apart from the same place so that what I'm sharing is
exactly what I saw or what I wanted to take an image of and and
so let's see really quick here go the images unblocked and
we're just going to fire through them these are the images that we took
and they they were taken with various methods the galactic core Lake cuts and
dark sky park I think we're kind of going backwards there's
that image Andromeda you've got uh spiral arms out there even through this Haze the heart
and the Soul attempted to make an appearance and there you've got the double cluster and a often little known
giant cluster malot 20 I believe is this around murac in uh in
percus Back to the notice the difference in the darkness level
received versus actual when you stack images like
this this gives you kind of an idea of if you were standing there looking at the Milky Way you'd see this would be
all white you wouldn't quite see as much detail you wouldn't really see the uh
dust Lanes like this but notice how the dust Lanes kind of mix in with the sky
that is accurate for what is there as opposed to to when
you stack your longer exposures you start to make this dust Lane get darker
all the dust Lanes start to show more contrast 30 second shot all of this Sky
glow wasn't there um it isn't as pronounced because you're stacking a
median stack it takes a lot of that out as
opposed to a single image where everything shows up including and I left
the ground fog in too um wasn't sure if I was going to get any Imaging done with that ground fog
and this is a camera that um does not have the hydrogen Alpha filter pulled
out this is a camera that does and so the differences in um you
know the uh white balance I typically try to match the white balance here don't always do as
good a job but with the white balance this is from the modified camera I like
the sky to try to be what I saw and if if the ground looks believable that's an
actual the actual shade of green then that's then I know I'm close and here's
the 30 second image and there's not much
there so you get as much as you image and
um I think with that I will go ahead and stop you get as much as you image but
depending on what you're looking for you know make the night sky your own and you
know lots of beautiful images out there but you know there there ought to be a
method to what you're doing there ought to be a uh you know what is it that you're going
after and you know and you keep trying even all of us who have done you know
the type of Astro Imaging that we do we're still constant constantly looking
for different and better ways to present what it is we want to present so so with
that Scott I I'm sure I ran over time but uh no it's absolutely fine it's
absolutely that is that is my uh first presentation I've actually done in a while along with uh yeah very nice very
nice I can so I have to keep you give a lot of thought and uh you pulled off some great images to to show us and uh
they're always beautiful I mean you do just some such amazing work so thank you
I appreciate it yeah I adri Adrian I was listening and watching
the beautiful presentation because more than your most of your others you were talking about
the process it was a process story of how you build an image so carefully and
different methods that could be used to build an image and uh I uh I just I just
I just loved it I I think it was the best presentation I've ever heard you give it was as perfect as can be and uh
and it was really I hope someone is going to inscribe that presentation in stone and put it in the
Lincoln Memorial next to the Gettysburg Address well I appreciate that uh
as always deid there's no presentation or image without the night sky to share
with this it's Beauty um you know again my your poetry is there and you know and
everyone else who loves a night sky and does this sort of stuff it's less about me and more about
presenting the nights sky in it you know as beautiful light as I can and not just
in certain places that highlight the Earth as more
I want to to the work in harmony so I'll take images in front of basic it looks
like a basic forest or it's a lake to me those things are beautiful you've got
Earth and the sky same universe just we're closer to the one we're closer to
Earth so we see it a little closer and um you know the two the two work together so that's it's it's about uh
treasuring our night sky while we have it one of the uh one of the things that
really kind of got to me was you during your during your discussion of your methodology reminds me of a story I was
at a at a uh one of these astronomy confabs and I walked to the Canon
boo and I spoke to the people there and I told them that I have a 20da and I
love it an ancient 20 da and they looked at
me and said oh we now have the 60 da you got to buy that one it's so much better and I said I'm not interested in buying
another camera I am interested in telling you that I love my 20 da and
again they said you have to get the 60 da blah blah blah blah blah and I just
waved at them and walked away I love my old camera now that my Nikon has well on
hard times I dropped it and it broke I'm back to using the old Canon da and I love
it it works just fine I used an old Canon 30d to start shooting the night
sky with and um the 6D that I used that I got modified probably a 14-year-old
camera very solid produces produced all but a couple of the images you saw in that
presentation and I love it it it's much better to be out in the dark with something you know than to Fumble around
with your equipment and stand in frustration and Miss what's going on
above you it's uh I've done that a couple times trying out different equipment and said you know what never
again am I going to be upset while I'm out under the night sky because what am
I upset for I didn't come out here exactly so that I could fumble around
with equipment and get mad and you know and not think about where I am and the
that nights guy under me it actually took me I remember it clearly I remember
looking up at a lot of stars surrounding the Big Dipper or you know the Great
Bear so the Big Dipper asterism I was frustrated because at the time years and
years ago I wanted to get a particular Galaxy that was near the Big Dipper and
I had such a hard time trying to find it and I was so frustrated and then I looked up at that sky and I
said I'm wasting this beautiful sky by being more focused on my gear Amen to
that Adrian I with you
that I I have abely I was um and I'm trying to remember what it
was it was the August 2017 total eclipse of the sun and it was a beautiful clear
sky totality began and I was having trouble taking pictures camera was all set but I was
having trouble taking pictures and I started to get angry for about three seconds and I thought Levy there's a
total eclipse of the Sun up there look at it I'm gled I changed my view fast
yeah absolutely I perspective yeah perspective here and I
think that's you know and then we'll we'll turn it over I think Cesar um has more perspective to share with us from
uh the Southern Hemisphere and um but we you know we we looked at Ron's gear and
a lot of us you know we we love the gear and there's nothing wrong with having
this great gear as long as we know how to use it we learn how to use it it's
serves its purpose um you know too often we can sometimes become wrapped in what
gear was used what are the settings things like that and you know we talked
about the process both of us kind of talked about process myself and Ron and
um and Lori you talked about your process too of how you went from writing
things down to now you've got your spreadsheet we all have a process because it has a purpose that's it's our
love of the night sky we're capturing what we're seeing and that becomes more
of the focus the gear helps you but just remember that you know there's there's a
wonderful Cosmos out there and uh every you know you get a chance to image it
you know just keep that in mind you know I'm not going to change everyone's Hearts there there's going to be a lot
of a lot of gear heads and that's how the industry keeps moving right Scott you got to sell that gear is someone's
got to love it but uh you know and most astronomers like the tools that they use
to explore once you buy that gear from Scott go use it and uh go enjoy it and
if you miss one like well-worn well used gear you know if it doesn't have a
scratch on it or it doesn't have something that shows me that you've actually really used it then I I'm just
kind of disappointed you know so right yep yeah yeah even that little telescope
next to theid has probably seen more of the night sky than any of my cameras
have and uh I've got a lot to catch a lot of catching up to do to match the uh
match that little scope right there next to you yeah you're absolutely right
Adrien on this particular telescope I witnessed the uh 1979 total eclipse with
this nice very nice long time ago and I've never forgotten it how ever the
best view I've ever had of the entire Sky ever was on April the 8th it was 20
seconds after I finished reading a short poem at the onset of totality under this
dark gloomy cloudy Sky when suddenly there was the sun and the
Corona and and I just about died I was so moved by it I don't think I can
imagine how that would look that's the sort of image I want to capture and that's why I've got an image similar to
that behind me because that's uh that was my goal when I went to perisburg just to capture how does it look around
the eclipse that's something we don't do very often or very well so so all right
Scott I think we've talked okay well thank you both of you and um
uh we will move on to uh another short video and um um and our next speaker
which is uh uh Caesar brolo down in Argentina so let's run this little video
first and um and away we go
[Music]
we're in the dark and in an echo chamber too here we go
hey um anyways uh we have made our way around the world here and we are down in
Argentina now with Caesar brolo and looks like he's set up on his
balcony yes yes this is the the balcony Observatory here in Buenos
artina yes and well you can see the sky but you can see
clouds this is a a real life view of this Sky actually in Bueno Iris
fortunately two weeks ago uh we had we had a clear sky
and as today we are talking about the deepest space going to the Deep um um
two weeks sorry two nights ago we had a clear sky night and the first thing that
we had was a conjunction of moon and the
speaker stars and um um before talk
about the sky I'll show you um gr of of pictures of D of our
Facebook our business uh because this sat this Saturday morning we made a meet
that um per periodically we made this
kind of meat uh with a time to touch let me show you this is social event in our
store and we love to make this because it's it's nice share the time with our
uh customers and friends um we uh it's a it's a uh how do
you say it's um a way to encourage people to
make more astronomy enjoy more the sky and sometimes we uh take
um we give a technical speech or something about you know information
about using of tele scope processing image uh um or uh mechanics and
astronomy Celestial mechanics we call it maybe in Spanish mechanic celes maybe I
think that this similar the same the measure you know of for example how the
asan people using astrolabio or um for example this Saturday was about H
history of astronomy measuring the the sky the the projection of the celestial
map I'm using uh Astros asts I think I'm
sorry that I don't know the the right word in English because it's maybe
it's a it's a word that that came from the Latin but I show you pictures of happy happy people in
our in our store yeah and you can use Latin words on the no problem this this
is the people that came to the store the meeting is a is an optical store and of
course full of telescopes this is me of course and this is the first people that came
uh if you're people if you're intending to share your screen you're not sharing
your screen yet oh sorry only only no no no I can't believe that I make this
sorry why I make this we all made this mistake yeah don't worry why yeah yeah
it's tradition Scott it's tradition exactly it's traditional yeah oh wow
this is good yes it is here is it much better C yes customers um yes maybe I I
I was to show myself yes yes this is our optical store
um um telescope store and is in is the
our store that is focusing to be of course of talic optic store but the
another apartment is is full of telescopes is it's um when people told
me in what Sako I I can bring my telescope uh no no only in the micro
cental in in the downtown ER store because it's our
telescope store because an Optics of course but because it's is where we are
I am and uh and the people say okay I go to the downtown store we have another
stores in different places different neighborhood of city of
buenosaires and it's a family business my wife for example is here in in
Palermo in a in a store that is only uh eight blocks from from my home my
morning sometimes go to the first to the palmo store and go to the and after I'm
go I'm going I'm go sorry to to the my d d downtown store well we are
here this is um okar fero that is an specialist in in this kind of terms
about um Celestial celestial mechanics um he he made this kind of
arabus the the typical Circle all instrument to measure the the latitude
the the highight of the the the Stars you know and what really ex what's really
interesting Kime Garcia that came to wois and we we approach um um to make
this all together Norm normally Garcia is my friend that live in in
mendosa um we have fun and talking about
the all the things that we really enjoy and we yes we enjoy another thing
more that because this was in the morning and we uh finishing the TS we
went to the street uh um um using telescopes uh in in the
street of course that many tourists came to to see to watch the the sun with us
and take pictures of the Sun and uh make observations and take pictures with the
cellone
too and for Saturday this is perfect and of course that we serve
coffee sodas and um medialunas medialunas is a
excellent excellent um uh thing to eat in the morning oh Half Moon we call it
this is like a crossan from France but better because it's from the
bakery from the bakery yeah very sweet beauti yes yes nice really yeah and this
is the pictures of our customers took uh because was very interesting the the
growth of of uh sunot sunot sunspots uh well what's what's really
interesting the the all the the the the completely experience is the second one
that we made next uh in the next Edition we are uh working in seral uh um
software processing um ex exos 100 ER tricks to use
better and sometimes something something fun is that our
customers um make voluntary their their talks no no us and this is better
because they share their experience using their years to share to
another people and this is the best way that we can do it because um we prefer
uh for example about gear that um that uh uh our customers share with the
people that their own experience well another picture of of the
sun talking in the street in the in the in [Music] the in the in the door outside the the
store and well this is was an excellent an excellent
experience and now I share another thing that
is um
here I'll show to block to
um uh two nights ago um not last night if not the another
one um 16 and 16 and 18 of
jun um because uh uh we had a clear clear sky not
not now but maybe maybe well in the end of the presentation maybe we can we can
try to to see something in this area because it's going to be clear but I
don't know I prefer show you the the the pictures that that I took and as I tell
you the condition for for the
last sh
um well well says it's becoming winter there though now right yes but but but
um incredibly the the the this uh is
something that mix said with um with the
[Music] the the the climate changing um is it's something that we
call it banito the San Little Summer of s St John and St John's
um it's uh uh first of all the the the
winter start harder here in May but in the the first the first M uh the First
Mid of of the month of jun of June uh
the the the weather is going to be more warm
and maybe next week is going to be harly for when of course that it's not
so it's not so uh cold but for us it's humid and cold um really uh is going
next week with a a storm and rain we return to the real winter but now I'm
using only this and I can I can uh stand here without problems well the
first um the first picture of the journey first of all I show you if I
can make I don't know why I need to share screen off uh starium but I don't
[Music] know I
try I think stellarium can't be in full screen mode
yes I found trouble sharing in full screen yes now you can
see okay okay well we are going to
to to to watch the conditions in the same hour but
I show you was starium is such a nice program yes is the best tool for for all
people of course and I just loaded it on my computer as well and yes it's uh I
think it's free yes it's free only for cell phone
you need to pay something if you need the the um some advant
advanced settings uh but if not uh you you you
can use the free uh for for a computer it's all free for the the computer is
totally free I don't know if you can pay something with a something over up
upgrade of of use but I never seen that for the cell phone for the cell phone do
you have a basic uh a basic um starting Edition and you can pay by
month or or by year um an upgrade Edition with uh for using for for
example moving telescope have have more objects you
know we can
put I try to show
something sorry
that H I don't know why sorry I was in January
sorry I was totally totally ah now
okay okay because I I need to show
the the the time was okay but the idea was to show you oh was this
Sky
yes was um I don't know what
six it's okay I don't know
what because do the moon a cult Braum no no yes something is something is
wrong I'm totally lost
because because uh I I I trying to show
17
okay ah okay okay now it's okay
sorry sorry guys I'm starting to show how was the
the sky two two nights ago we have now it's okay speaka and the
moon this was the the condition that we had where where um this was a confusion
between speaka and the
moon I see I yes this was the condition of the
sky I try to the it okay
okay 17 yeah well I show
you I show you the picture that I took of the Moon okay
this was the the the base of the Moon B of the Moon very nicely done yeah very
nice yeah I think Robert Reed would like that one no no no please no no no I
think he would love it what do you think Adrian he start he'd start pointing out every crer exactly exactly be like this
crater and that crater and that Mari oh you Reeves loves look at look at your
hat L real here it's beautiful you know probably almost any decent image and
this is more than decent uh you know he would he would love to look at it
so next week we we can do something that is is uh we can process a lunar image in
in a live in live
um sorry um well this is the first picture
that I have second one the journey going
outside of of the Galaxy is H well we can talk about
speaka that is going going outside the plan
planet the planet our planetary system and we can
go second one is is Omega Cent Omega Cent we we
told that many times that it's uh is um the remnant of an all galaxy is
the nucleo of an Galaxy maybe maybe many astronomers
think um but certainly it's not only imagination if not uh with um different
measures that they took H they think that a this in the core inside of this
uh Global huge Global cluster because this was at the center of a galaxy a
Galaxy the core of the Galaxy in the past the Stars the arms of the this
galaxies was absorbed was taken by the our milway
galaxy and something interesting is that you can found different colors
of the Stars blue red and it's a huge huge um
glowal C cluster in the South Hemisphere and very something
interesting is that a a car this inside have two maybe have
two uh black holes
inside two blocks yes yes and and you know I've actually seen it sometimes it
travels far enough North to make an appearance in the L excuse me lower
United States I happened to be there when it was um far enough North for me
to see it unfortunately it was the full moon I could still barely see it um or
get an image of it I couldn't see it naked out had I been able to see it on a
new moon it would have been it would have been thrilling and I would have probably gotten a lot more of the stars
that are in there no no and it's a miracle that I'm
with this telescope I can show I can see this kind of of uh objects this is
really incredible um it's really far far
away um more far away more Far Far Away going outside I don't know maybe if I
have I need to see which one is is closer and which one
is uh in a longer distance I have another picture that I
took but this one the problem is that I
uh take this picture near to the near to the um to the H not the sunset not to
the the morning was the tarantula
neula and um many of the the shots I uh
I uh how do you say I'm uh miss it
because they was near to be uh to the
morning uh in the rising in the in the rise er um
screen not here yes it's more easy to the F
okay I choose for the first um of this picture I choose to take a monochrome
image and prefer no so zo to show
I am processing the the color image now but but for me was a little
sorry complicated because for me I choose first to process uh fle H
tarantula nebula and black and
white and it's full of details and full of stars you know between
weldings and this is an area of you can
compare an area similar to the moon and this beautiful this this um
this nebula is so big and so bright H sorry sorry I I I don't um I don't hear
you Scott can you can you can you hear
me oh I can hear you sayar ah okay okay
okay I couldn't listen to uh to
Scott well Adrian look that it the the size of of the of this nebula is so BR
and and um is a nebula far far away is in our
accessory galaxies like a like a large melanic cloud and the size of this
nebula and bright is so so H strong that
it is a nebula far far away and is one of the nebulas outside
the Galaxy because the large melanic cloud is outside the galy galy is our
galaxies small galaxies accessories like a like a it's part of our group and the
nebula is so bright that if the nebula is
H is being uh at the same
distance like oreon nebula that is closer to to us uh we we um with the of
the paranta nebula at the same distance
we could H going to read in the night
because it's so bright that that have enough light to at
the same distance of or your nebula uh is enough to bring uh as
light the quantity of light to to illuminate the entire
Sky um read in the night fortunately we don't have this in the
sky it's it's far far away it's far far away but so you're so you're calling the
tarantula nebula the largest amount of light pollution
ever yes absolutely absolutely with if you if you see the the you can see
here the our the clouds because the quantity
of light going to the sky from the from the city
is so big that really um the you can see
the clouds that is crazy but imagine imagine adding a nebula here
with a yes maybe with we are uh I don't know how
um many many times for example I I
I I know that in some uh
supernovas in some supernovas I don't remember if wasak Karina or another
another Supernova that explode inside our
galaxy sorry that I don't remember the which one was the people could
read in the in the night and imagine this nebula no no no
more night for a people or people sleeping with
h with something to cover their their eyes no no that's right but yes and and
this is something I could took the this
picture um in in uh two weeks two nights ago
sorry and really was a black and white picture but I'm happy to have yes
because all this is the the best way I choose uh a monochromic picture to
separate the quantity of objects because this was this photographed in the middle
it's photographed in the middle of the city right yes absolutely absolutely was
in this side this between two sorry maybe I can show you where is
the was in the here imagine that yeah
unbelievable yes it's it's totally difficult um make the processing because
I have some gradients from for the right of the welding because look the quantity
of life that they have this buing but it's a it's interesting and interesting
uh how do you say um it's interesting uh something that
you need to win against the things uh I forget the the word in English but L the
safio is something like a um what I
having there but you know it's it's something that that really I love I love
to to make this kind of things because uh you have a lot of information a lot
of stars really is optically uh the quality of the picture is is good of
course that is it's not the best picture absolutely not it's not the best it's
maybe something wrong but we are talking about in if I say sometimes say okay if
I can if I can take this picture you can make a better picture um you uh
you you can I say to the people the best way is having your telescope in the
living room totally assembled maybe with something with cover if you if you have
a in a in a box cables uh you know all prepar because do
you have have an night that you have some uh opportunities and
you if you have your telescope in a in a bag in a box you know is the is the the
wrong way no no you need to telescope you don't have an observatory
okay but you can get ready your telescope in your living room and that's
right go outside uh and okay this something like
a like you can you can H make because it's for
everyone in different levels of Gears it don't need to to be something
complicated I use it exactly because for example
I ER any one of this pictur that I show you uh was guided uh I have read this
but but um um as I I work if you if you
work a little effort more make a a little effort more to to get a precise a
more precise alignment polar alignment you can use in a five seconds each shoot
and assembly together the aditions the lights and make a fast and you have a
fast picture and you have a lot of information and see your picture red in
Wikipedia about the object that you take and you have a lot of information that
that really is it will be something rewarding for you talking to the people
customers of w me too of course and this is great really I I enjoy with
Adrian um and take this amazing pictures um sometimes I see
the pictures only in in the presentation but when I go when I go uh to to their
uh official page and FL I don't remember where for example in in Facebook I open
I open the the ad pictures in the in the screen and
there uh and this is something that um I I imagine that ad
you uh some spend a little of time reading something about some nebula that
is in the sky or said why I can't do
this and this is Magic because it's a red color between the Milky Way and this
is we we um consider to see the pictures but the the is a mindblowing the things
that every night show to us in the sky
and really we are um how do you say really we are
um er we are we are lucky to to to have
this I enjoy this one that for the people you know is it's a it's a empty
Sky maybe the people can count ER count
five stars in the sky but the the treasures despite that this in from the
city or dark skies in the in the in the in farm areas open
areas are in Trel are are um open to to
to be explored explored by the people this is really really
interesting I don't know if I have really another
one ah yes I have well this is my my last
picture is not ready but I have one one more that I can show you of sento a
another galaxy very very far far away the end of this journey tonight
right screen
here this was my my my last picture
um the last week it's impossible to make more but I'm happy to to have this
because it's a very look that for me it's enough
is is the the last one that I that I took um and the details are very
interesting of course that it's not really totally have noise you know but I
love because it's with this small telescope that I took this from the city
and senta is uh really a it's a 13 Millions
ER like years I don't have a really to to have
this really all with this small time St
moment okay for me you can see the the the share screen
no yes we can ah okay okay okay well this is was all my presentation
I'm I don't have I don't have chances if I can make
a live IM much of uh Omega sent or something I advise you
Scot maybe after the the talk of marello
or you know no problem you know Cesar one of the uh
wonderful things about your lecture just now is I had to miss a little bit of it
but uh here I am uh one of the wonderful things about it is it
shows one world one world one sky with all the politics going on and all people
yelling and screaming and throwing buses at each other and engines of
trains when the night sky sun goes down and the stars come out whether they are
where you are or whether where I am or whether where Adrian is or Lori or Ron
or anyone else here tonight or Scott it's one sky and that
brings us together in magical ways that it's so difficult to to Fathom and I
just wanted to thank you for that yes yes I I'm so happy that you
tell this and and really you are a treasure
David uh because um it's so important that the people he you because um as
many times I I tell you and I'm told to the people that you are uh sharing with
us this special times for for for me especially is a honor that I never and
never h expect this and it's so special
because you works by many many years to to teach astronomy um to the for the to the
people is really really amazing unfortunately my English is so short to
to maybe to see or to to express more uh but I'm I'm hope that I can express uh
uh my grateful to your uh to you your
participation each uh Global surar and for me it's a hon really thank you and
that brings to mind the the most precious word of the entire Global star
party which is global it's all over the world it doesn't
matter what you believe or what you don't believe but the night sky is for
all of us and I think that's the most important thing about our star party to which you contribute something truly
unique W thank you this was Cesar you Mar
Marcelo uh Maxi Nico the hammer introduced me to what the southern Skies
looked like and it's one of my uh one of the highlights of being on global star
party is seeing the sky in places that I can't get to right now but sure wish
that I could one of these days make it a reality instead of just the dream of yes
I'll be there eating the barbecue and looking up at the night sky um that's
that's something that you know I think makes the makes the program truly special and that's you know in addition
to the you know just the number of people who love astronomy love the night
sky from all walks of astronomy you know the great devid who will never
he'll never tell you I'm such a great person but your love of the night sky
exudes everyone's love the night sky exudes from uh the presentation so I
learned just as much from being on global star party as I do um you know
the the actual presentations that are coming um at home doing Outreach um you
know now that we're in a period where people are getting outside and the media
is putting things um out there for people to try and go and look up um yes absolutely
yeah there there are complaints that the media over sensationalizes and overhypes things and
there's some truth to that and I don't know Cesar if the media and Argentina does the same thing um the sky is so
wonderful there I don't see how anything could be overhyped in the southern him spere but the thing that I've told folks
is we have to be careful about how we respond to that
because if we tell people not to trust the media well who are they going to
trust us and the media is actually there
for us to work with and to say okay they said you'd be able to see every single
planet well it's not true but you can see this this this and that and it's you
know it's is beautiful we we take the all we have to do is take some of the sensationalism out of it but they are
already interested in night sky because of what they're seeing on you know the media is saying this so we've got the
interest we cultivate that interest we don't necessarily tell them well
everything they say is wrong and you know and everything because if we lose
that spot AR getting it is going to be much more difficult now you can always
take a telescope plop it out on the sidewalk and or like you do in global
star party it's essentially the the electronic version of you taking us with
you plopping your telescope on the sidewalk and getting the image tonight may not be a good night in Argentina but
um it's the same sort of thing everyone gets curious uh just really quick to
everyone we just we just did a uh back to the Moon um thing where we were on
the lot we were in the corner of a university University of Michigan in a
library we pointed a bunch of telescopes at the moon and it was amazing to see
the various and different types of humanity that uh could come by students
Skeptics folks who didn't think we landed on the moon folks that are more concerned about there looks yes every
single one when they look through those telescopes we had we had a 14inch we had
my little 5 inch spotter we had a projection of the Moon uh Astro imager
was there I even had him looking at it through a little spotting scope um or
binoculars everyone from The Devout religious to any type of human any type
of human the ones that want to talk politics they all stopped and looked
through that telescope it caught them by surprise they were all amazed at what they saw
and for a brief moment they went from whatever their facade was to being
themselves enjoying something you talk about the moon well it's always there
don't even take the moon for granted because it can turn people on into astronomy and it it was such a wonderful
event we had so many people look through our telescopes and ask questions and
hold conversations and it's the the power of just one bright object in the night sky
can do that um it's I think it's something that's sorely needed so you
know I think we just have to be careful how we uh how we interface with the
general public let's make sure that told we encourage that we we see a show a TV show with my
kids um that is something about aliens coming to the hair and conest and this
is the three body problem maybe you you watch this in
Netflix um the idea of the of the aliens
to to win and Conquest the Earth we never think in this in in old movies
that is something about the idea that that the media the idea of the aliens in the in the in
the this TV series is kill Scientifics and they win because they
need they don't need Scientifics to resolve problems to to fight
against uh aliens because the aliens think no no we need
to kill the science kild the Noland is so powerful and the idea is is really
they don't think in to kill generals Colonels of the army if not scientists
you know this is the I say wow they think in the same way that uh today um
how work the media with the culture um
the nland that any any time is more that you tell that is more uh um
how do you say low the the notion of the people every time that that you need to
explain why why the be the
astronauts went to the moon 1969 you never stopped to explain this
but maybe if you are in in a telescope showing the moon or that you tell me the
most the most common un sense for us uh but it's a is a common question of the
people really you think that they came not fortunately it's not for all people
and the kids of course that never never thinking this they they know that is
real but fortunately the young and K people never but many million people ask
the same question say you really think that they went to the moon come on and
okay my my explanation my explanation because it's two weeks ago I had this I
I received the this question in a school for a for a parent not for a
kid and and really and I say him to to
this parent this men that um if you see if you see the
technology in the same world world and really you can investigate the
the amount of Technology from the second world war the horrible things but
amazing technology things um the extrapolation of this
technology is going to see that in the six 1969 the
people the NASA or whatever have the enough technology to go to the moon but
the people still love to think that was all a movie or and this is something
that have connection with the very low profile very low level of information
and quality of culture and education especially of the media but it's in the
entire world in the entire world I sometimes I know that you're a
lecturer you're a professor and come on you're a
hero well I'd like to share a little story about this Moon thing with you with all of
you I was on July 20th 1969 I was at
Camp Min Brook as a as an astronomy counselor and we had we had all gone to
the auditorium to watch the launch of Apollo 11 we all went to the auditorium to watch The Landing that
morning and then that evening I went up to the head counselor who had just announced that we would be having free
play after dinner and I said Mr head counselor don't you want to assemble
everyone up in the auditorium so I'm going to watch the moonwalk and He barked at me and he said go back to your
table and do your job which I did but I think the the owner of the camp who was
sitting nearby overheard what I had said immediately he stood up he called for
everyone's attention he said evening program is cancelled tonight history is
going to change the world is going to become smaller and at the same time
bigger and you all must be a part of this immediately after dinner we are
going to go directly to the auditorium and we are going to watch the moonwalk which is what they did
now you know there's a lot of fuss I mean did we really land morning well we did and I remember that night you know
the whole evening went on and it was there were times when it was light and people were talking and it was time it
was more heavy and we were watching but then suddenly they had the live image of
Neil Armstrong standing on the surface of the porch of the lunar
craft and in the auditorium there were kids who were six years old and then
there was me and there was the camp director and we were all absolutely
silent as he walked down the ladder yeah and he said those the words that he said
and we looked at Walter kronite as he rubbed tears from his eyes and you don't
forget something like that and uh I've never forgotten it to from that day to
this and I just wanted to share that with all of you yeah it's amazing story you were
there to see it live I was born in 1971 and uh wouldn't remember any of the
programs showing the moon landings and I do remember that uh the public sentiment
and that's something I've heard the public sentiment for the moonlandings started to
change um you know there I think uh fing
revolution in juneth which is coming up no one can see the fist uh my community
used that moon landing as sort of a they can put someone on the moon but they
can't do XYZ blah blah that kind of leads into the political discussions um
yeah and of course my own take on that is yes we put someone on the moon but
we've become kind of a culture that doesn't want to take the type of risks at least here in America we we're a
worldwide Global star party but the risks of doing it have been
greatly muted in favor of safer Ventures
or rest assured you know everything you know everything must um happen the right
way or we're just going to abort it um the uh tragic deaths of the uh three um
AST Nots from Apollo one I know white is one of the names I try to remember their
names but uh I I think Dev Scott you all can fill me in white chaffy and Grom
yeah yep white chaffy and Grom sacrificed their lives to get to where
Apollo 11 made it you know the other Apollo
missions were able to go to the moon and astronauts when they climb into those
capsules I mean they are sitting on top of a bomb okay yes so it's uh they they
know that it's dangerous but we climb into a car every day and race down a
freeway and you know almost every freeway has lost people but we don't
really we're comfortable with that somehow you know yeah we true story each
of the um Apollo uh missions have had a logo a patch that
had the names on it and Apollo 11 um the astronauts chose not to have their names
on it because in their minds they said that everybody involved in the mission
at Nasa and up to that point were the ones who made the Apollo Landing for
Apollo 11 happen the T thousands of people
yeah thank you foring worry that's really very yeah very very unselfish it was a
very unselfish uh and everything was passed down from the next mission even I
think the Gemini missions there was we learned something gradually this wasn't
okay let's just go to the Moon you know and then this isn't a Tik Tock video
where someone says we're going to go to the Moon President Kennedy and then the very next clip you see someone dancing
on the moon it didn't happen like that no and um it's you know these things
take time and I know the Artemis mission is working within the you know the
confines of well we don't want to show disaster when we you know when we
launch with humans everything has to be double triple checked we do hope that
the emis mission does fly and fly success y because that may re
reignite Um passion for going to the Moon passion for all things
astronomy and and it might finally uh you know those that may didn't believe
we went to the moon in 1969 and the years following but something about
having your own generation do something well that we can believe um will there be Skeptics yes
will there be people that are more concerned about what's going on right on this planet there are um I was never one
of those and I suspect neither anyone listening or anyone who's still in this
um you know during this presentation we like to know what else is out there we
even at our Advanced ages we still have curious almost childlike um Wonder for
what out there tonight's guy and I think you need that um in order to I wonder is
something that we all need we yeah yeah you don't you don't Advance if you don't
you know want to know what else is there yeah I wanted to pick up something IAM you just said that you hope that the uh
the new moon program will inspire more of the public to get excited about astronomy and the night sky and I would
like to very respectfully disagree with that all we need to get excited about
the night sky is the night sky you don't need a l moon landing you don't need a
Mars Landing you don't need NASA although NASA really really is a helpful
organization my favorite government agency all you need is a little bit of
passion imagination and you go up and see what that nice guy is like
every very true and I I would wish it were that way and I guess one of the
it's one of the ways I try and use my images de is take pictures and say this
is what the night sky looks like imagine if you could see all of this and um I've
gotten a lot of support from folks who you from all walks of life and um I view
that as a greater Mission than just simply making pretty pictures one thing
wanted to add to your beautiful pictures is that sometime in the great future as
you're spreading your pictures out over the web and into the night sky and into
space that maybe a 100 or 200 years from now some other civilization is going to
see them and that Civilization is going to look at your pictures they're going to say I know the horse head NE I know
it but what I don't know are the trees that are in the very good point
and uh let's go take a look at that particular at that particular place
where Adrien took that picture and make contact with Humanity it is possible
that your pictures could lead to the first contact with an extraterrestrial
civilization very very good point I actually believe that and that's you know these we've got a lot of pictures
out there and see to me that means the pictures where you've got a little
Milky Way over here and it's sort of a backdrop to some sort of
amazing artificially created thing aliens aren't going to be able to find that planet because it isn't real but
they look at something myself and then others who use real Landscapes that's uh just more
reason for me to continue to produce images in the way that I try and do it
which is well here's a real landscape and um this is this is just some place
on Earth looking at the night sky and the beauty comes from just being the
night sky itself and wherever it is it's a calm and Serene the light from
Starlight hitting the um whatever foreground um those are the images I
like to take and of course I love taking it around water maybe there's something to do with source of life or you know
any planet in which our type of life form can live on there's water somewhere
and I'm always drawn to it so probably something to
that yeah I I have been um reading about the uh the science of happiness and
wonder and uh psychologically they're saying that humans
need on average every two weeks a major experience of
wonder in their lives and when you don't get it uh you can fall into uh some level of
depression and uh so and you can experience it in so many ways you can see it in the you know uh a face of a
baby or uh you know an amazing sunset or you know an incredible view of a nebula
or a Galaxy or you know understanding something that is beyond you you know and beyond
your normal a mundane experience of life you know and this is this is very very
important and I think just now um I mean it's philosophically been brought up and
you can find it in literature and all kinds of stuff but uh scientists are now starting to pin it down and uh um and
there are actually uh university courses that teach it and
so which is very interesting so and uh you know amateur astronomers
astrophotographers get a lot of exposure to the Wonder and the amazing uh
experiences of um you know personal exploration of the universe so yeah and
you know Scott it's a shame if we we have all that opportunity
and we use it to complain about our equipment um or or complain about
anything or complain about anything I I catch myself sometimes um looking up at
the sky and saying ah this sky is no good and then the other side of me has to come disciplined and say any sky is a
good Sky it doesn't have to be this perfect I will agree with you on that it
doesn't have to be the perfect sky that I I see at okex and even even the okex
guy isn't always perfect but any opportunity at all to see Starlight is
you know it's a it's a good night that's right that's right well thank you so
much everybody for the thank you to the audience thank you to our presenters um
and we will be back with the 152nd Global Star Party um really enjoy uh
putting these uh together uh honored to uh share this um the hosting with David
ly and really honored to have all of you come and give your presentations and
express um you know what you do with uh uh your views of the universe so thank
you so much Scotty and God bless you oh bless you guys too thank you okay all right so I am going to
close out unless we have somebody wants wants to add something here at the very end but um I think we had a wonderful uh
uh 151st Global star party thank you good night all good
night good
night Uranus is the seventh planet from the sun and the third largest planet in the solar system
it also may have the coldest interior emitting far less heat than its counterparts Jupiter Saturn and Neptune
it is known as an ice giant because it contains more ices including water methane and ammonia than Jupiter or
Saturn and while NASA's learned a great deal about this planet over the last three decades there's a lot more waiting
to be discovered back in 1986 NASA's Voyager 2
spacecraft flew by Uranus making it the the first and only spacecraft to visit this distant
planet previous observations show that Uranus has a unique tilt of its axis so it rotates almost on its side causing
its poles to actually face the sun no other planet in our solar system has this
feature in its quick Sprint past Uranus Voyager discovered 10 new moons orbiting
the planet that had not been seen before and in the decades since even more have been found during its encounter Voyager
also saw new new faint rings and explored the complex
magnetosphere Voyager only briefly viewed the planet's five major moons Ariel Miranda Titania Oberon and umbal
these moons have a wide variety of terrains and geological features some of which indicate possible subsurface
oceans small Miranda has chaotic terrain with deep canyons and Tall mountains but
is likely now frozen solid Ariel appears to have youngest surface with few impact
craters while Titania has a very old surface the lack of large craters and presence of a large canyon system May
indicate ancient resurfacing Oberon is also covered with craters and has valleys and large
mountains umbo surface is the darkest of the Uranian moons and it Sports a strange polar ring the origin of this
ring is still a mystery but scientists believe that it may have been formed by an icy impact
since Voyager groundbased telescopes and the Hubble Space Telescope have played the leading role in our understanding of
Uranus since 1992 Hubble has watched the slowly changing Uranian seasons
including changes in its unusual pale blue color and polar hazes telescopes have also revealed that
Uranus has a complex weather system with massive storms that can last for months or even years with wind speeds over 500
mph [Music] the ongoing search for ocean worlds and
life beyond Earth makes Uranus an exciting Target for the James web Space Telescope and for future up close
exploration new data will help scientists to understand the formation and evolution of Uranus as well as its
moons and rings and provide clues as to whether liquid water May reside beneath their icy
crusts the fascinating properties of this planet discovered in just the span of a few decades reveal that unlocking
Mysteries here can help scientists learn even more about our solar system and our place in
it I'd like to invite all of you to uh to come to the next Global St party they
are run by Scott Roberts of explore scientific and me we we co-host this
program and uh it's usually done on Tuesdays and uh usually at 6:00 or so
Central Central Time and so I hope to see you all there my name is David Ley
and I hope to see you all at the very next Global Star Party
thank you
