Hey all. Out last night with some sketchy seeing trying my first round on m31. I didn't realize how big it was when I started (particularly after mars as my first and only astrophotography experience). So here's the middle-ish of it. 127 Nexstar SLT, EOS 550d, 30x30sec @1600 iso, a couple darks for noise, DSS stacked, post processing in GMP.
So I think I really need to look at post processing. I really didn't know what I was doing in GMP but I was able to get some good signal, although also a good amount of noise when I stretch it far enough to get some of the body of it. Anyways any advice is necessary. Given I don't want to switch up equipment maybe I'll try m33 next. Any advice for post processing images in GMP is helpful.
