I was up early on the morning of March 1st and decided to open up MSRO StationOne for some quick imaging since the sky was clear. The seeing not so good. I decided to image M51 and here is the result.

I had to send my scope back to ES for repair and collimation. This image is first light taken on 12/19/2019 of the Rosette Nebula. This image has the same spacing as the Horsehead image posted previou

TDM sounds cool. I've thought about designing a mount using shaft encoders. Seems like you should be able to essentially eliminate periodic error, backlash, plus other benefits over counting motor pul

#G11 #astrophotography #TDM

Jerry, Two questions about TDM. 1) How does it deal with backlash in a less precise mount such as the EXOS2. Being as it is an encoder, if the RA needs to reverse directions, does it reverse to a know

Hi Bill, Thanks for your kind words about my image. We don't auto-guide at the MSRO, we use the Telescope Drive Master (TDM) drive correction system which is a high-resolution (0.125 arc-seconds/count

Just Wow! -- look at all that smokey detail! Was this with or without guiding? Bill

#G11 #astrophotography #TDM

Awesome picture. Great, crisp detail in there. I second the 55 mm back focus to the focal plane. I believe that is a camera industry standard. Bill

Jerry Very exciting shot this. I have a question (1)You take this M42 only one sub 68min or stacked some shots? Now Thailand has little bit clear sky. So I try to take some pics with IExos-100. If I c

Here is an image I took this past Tuesday but didn't have time to process until today. I typically try and image the Orion Nebula once or twice a year. I was up late and decided to take about an hours

Jennifer When I grow up I hope I can take such a picture. Beautiful. Thanks for sharing Wes

Hi Jennifer, We use the 3-inch 0.7x FRFF on the 6.5-inch ES 165 FPL53 ED APO CF scope (with a Moonlite focuser - I think they are the best) in the MSRO and it works pretty well. The scope is F/7 and w

Beautiful image! Id be very happy with results like that. Once you get that spacing nailed ( im sure Jerry can help with that) i think youll be very satisfied with the results! Myron Wasiuta Director-

Edited to include photon collection details. Hello Fellow PMC-8ers: I don't normally share my images with the group and this image in particular has some flaws related to the Hex Focuser sagging and s

Hi Joe, The QHY 163C TEC CMOS camera used was set to a QHY Gain value of 20 and an offset of 20. These settings correspond to a Gain of 0.29 e-/ADU, readout noise of 2.2 e- and a dark current of 0.006

Very nice Jerry. Unguided! The stars look perfectly round to my eye. How hard did you drive the amplifier gain? When you looked at your histogram, what percentage of full scale was the maximum bin? -J
