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

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

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
