"For Professional Level Scientific Imaging for the Amateur, Explore Scientific Equipment Can't Be Beat!"
"Field testing gives us the edge we are looking for... As Explore Scientific's Field Testing Team Leader, I work with select individuals to make sure that our products are rigorously and continuously tested. We feel it is the best way to get long-term, detailed feedback on how our optics and mechanics perform under a wide range of conditions. We use the suggestions made by our field testers and from comments made by all of our customers in our program of continuous improvement of our products."
"The Explore Scientific Telescope Drive Master (TDM) is an important tool that helps me focus on imaging rather than the equipment..."
"When I first started out in astrophotography, I learned all the ins and outs of auto-guiding, but I was spending a lot of time doing setup and management of my guiding equipment, and not focusing on my imaging. This was eating into my time and productivity, and I was thinking there had to be a better way!
When you are trying to do minor planet astrometry, and you have a portable observatory, you really need to maximize your efficiency in setting up and tearing down your observatory.
In my opinion, the TDM is the perfect solution for portable observatories. Because it allows you to setup quickly and start imaging right away, you
don't worry about your mounts tracking ability, or it's performance... It just works.
Being an engineer at heart, I wanted to really test my TDM in order to fully understand its operation and performance. The whole TDM team, Scott, Attila, Istvan, and
Tassilo were there when I needed them to help me install and operate my TDM system. Once I recieved my system, the installation went flawlessly, and I was up and
running within a couple of days.
I was also pleased to be able to share my initial testing of the TDM with Dennis DiCicco of Sky and Telescope Magazine. I was rewarded with a mention in his article on the Telesope Drive Master in the October 2011 issue."
Jerry Hubbell and the Explore Scientific Carbon Fiber ED127 APO Air-Spaced Triplet
"In April at NEAF 2011, I told Scott that I was interested in maybe upgrading my Synta 120 mm ED refractor to the Explore Scientific Carbon Fiber ED127 APO Air-Spaced Triplet.
I was always wondering if I was really getting the best images for my minor planet work, and also my high-resolution lunar imaging work. Scott offered me an unbeleiveable price on the scope, and I couldn't turn it down. The results speak for themselves! Here is an excerpt from an email I sent to Scott about my first light experience with the scope at a public star party our astronomy club was having:
...After doing an alignment on my EQ6, I pointed the 127 ED to Saturn, and with the ES 25mm eyepiece, it looked very crisp, and bright.
I found myself saying wow a couple of times to myself as I brought the image to best focus.
The visitors were very impressed with the image, and I was greeted with Oohs, Ahhs, and Wows, from several observers. I was very impressed by how even on bright Saturn, there was absolutely no false color fringes, the stars were tack sharp even with the 7mm out to the edge of the field. I bumped up the power with a 2" 2x barlow to 272x and even though there was some dimming, Saturn was still pretty bright. Unfortunately I don't have the highest quality barlow, but the view was still the best I have seen out of any scope I have owned...

My high-resolution lunar imaging was kicked into high gear after I recieved my scope. I have recently purchased a Televue
4x Powermate, and using the Explore Scientific Carbon Fiber ED127 APO Triplet at f/30 (3810mm FL) really has let me get
the maximum performance out of the system. You can see more of my images here.
Springer Books has released Jerry's new Book "Scientific Astrophotography: How Amateurs Can Generate and Use Professional Imaging Data". This book will be available in the Explore Scientific Shop.
New version 1.06b of the TDM TE Recorder!
See below for the latest version of the TDM TE Recorder for your Telescope Drive Master. This version includes a new nightview display and other improvements. Go to the bottom of the page for download!
Hubbell's TDM Software
Jerry Hubbell has independently developed an improved version of the TDM Monitor software called TDM TE Recorder. This program records and displays the Tracking Error (TE) as provided by the TDM and also
records and displays the Right Ascension (RA) of your mount by connecting to your mount's ASCOM driver. He has made this software freely available to Explore Scientific customers for their use.
This latest version includes some improvements including the ability to save and load parameter settings. The biggest improvement is that the new version includes a PID controller using the ASCOM pulseguide API.
The controller uses the TDM tracking error (TE) signal to correct your mount's TE via the ASCOM standard pulseguide command. This allows you to dedicate your mount's autoguiding (ST4) port to your guide camera to correct
the long-term drift typically associated with polar mis-alignment.
