Description

This is my second M31 Andromeda attempt at 400mm fl. Now focused with the Bahtinov mask, modified DSLR and more acquired lights compared to last year (2016: 130x90s, Now: 113x120s). Only 2 nights. It was the max I could reach due to the bad wheater... really bad this year :-(

And I tried to process more subtle this time (not that much color correction).

I like the result :-)
