Last Saturday night I planned on an all-night session just on M31 hoping to get as much data as possible.
Weather looked promising when I was setting up but unfortunately turned nasty through the night with high winds, cutting short my attempt at M31.
Still I did manage to get PHD guiding very well with 10 min subs and so here is Andromeda from my place which barley rises to 9°.
Four x 10 min light, (6) dark, (15) flat, & (10) Bias frames.
Originally planned on more subs so I set ISO to 400 which if I'd known about the weather change I would have used ISO 800 instead.
I've also attached a mono version as well.

Andromeda M31
Back in 2006 I tried imaging M31 for the first time, at only 16 min total @ 1600 ISO,
see this thread, and you can see a vast improvement with this attemp.
Hope you enjoy.
