Another 20 minutes added to 11.5 minutes of M31

Hi,

Further to my earlier post of 11.5 minutes of M31, I managed to salvage 4X300s of almost usable subs from the session and I have done my best to combine them to the best of my feable ability so this is the result of 31.5 minutes of less than perfect data. Processed in PI and PS. Still very noisy but this  is all that I can do with this data. I still can not get rid of the horizontal gradient at the bottom of the capture, any ideas?

Merry Christmas and best wishes to all,

A.G
