In the annotated version of you can also find IC2694 (~940M Ly away) and IC2745 (~500M Ly away) which are two spiral galaxies similar to M65 and M66.
Last Winter I made my first attempt at this with the 1600 and it came out poorly as I was still figuring out how to even use the camera. This time around I’m really pleased with the outcome. I did have to crop out some bad parts, but this LRGB version is nice, given the brightness of the Moon and in and out clouds for two weeks. Total integration time is roughly 15.5 hrs of time across all 4 filters.
