M31 Andromeda - all 16 hours of it :)

Right, I'm officially sick to death of Andromeda! This is now 16 hours of varying sub-lengths and ISO settings, and I've reached the point where my skies are going to yield no more. Quite depressing to think that 16 hours here produces the same result as perhaps an hour under dark skies - so this is my final attempt ;) (Wrong!). Better processing than the last shocking effort I think - a little more subtle, and some fainter detail evident (and some detail less evident as the contrast has been turned down a bit!)


Having spent a fortnight thinking about very little else, I can now get on with my life :)
