Description

On this night I wanted to shoot another subject, but after some minor equipment issues, and more importantly after being completely surrounded by clouds for almost an hour, it was alread too late, and I had very little time to get a proper shot at it.

So I decided to go for the evergreen M31, a very easy subject, showing so much data even with a relatively short total exposure time.

This is the result of 1 hour and 12 minutes of exposures (originally 1:45, some frames were discarded for their poor quality).
