I snapped this guy just before he went behind the trees tonight. Still during twilight, it was about 9:15.
Very happy with the results! Never have tried imaging M1 before that I can remember.
5 minute exposures, 2 LRGB and 1 for each other colour.
Oh, and the observatory roof was obscuring the telescope a bit, probably about 1/3. (pitch of the roof is to the north)
