Thanks Bave/Darb (?) and Phil. It surprised me when it started to come out during the processing.
Funny you should say that Adam.
I'm a bit hampered atm with some trees. My window of opportunity is about 2 hours or so. Unfortunately M31 doesn't get to my "window of opportunity" until around 12:00 at this time of the year. I might have taken a few more but the fog moved in at 12:30 but I persisted until about 1:00ish and then decided to pack up. Then the fog decided to clear at about 1:30 of course
