Description

This is my attempt to process David's wonderful M31 widefield image using a different processing toolchain than David.

http://www.astrobin.com/317885/ (see link above)

We had tried to find a better way to deal with the huge gradient and vignetting in his raw data. Unfortunately I could not manage to improve David's result with my tools. The most noticeable difference is my emphasis of the dark clouds on the cost of a reduced halo around the galaxies. So I still don't have found a good way to increase the halo with my low-cost tools...

Thank you for the cooperation, David!
