Messier 31 - Andromeda Galaxy
This was my first attempt at M31. It's so huge that using my 6" SCT isn't really an option (even with focal reducer). I removed the OTA from the Alt-Az fork arm and mounted my DSLR with 55-250mm zoom lens in it's place. I figured I could get a little longer images with the tracking.
