This M81 ("Bode's Galaxy") in Ursa Major done from my light polluted yard. 78 minutes luminance, 30 minutes each R, G & B, 3 minute subs. The image has lots of noise and gradients, which I've attempted to remove. I used an AP 130 F/6 operating @ F/4.5, SXV H9 CCD guided by an SBIG STV/Efinder, Tak EM 200 Temma 2 mount.
