Description

First version was stacked with the DSS and only processed with Photoshop and a bit of Lightroom.
In the second version i started with previous picture and played a bit with Pixinsight. But i was not happy with the color balance because i didn't made it to see the red core of M31.

Finally i decided to start from scratch only using Pixinsight and again a bit of Lightroom at the end.
