Description

This is a composite of RGB obtained with the L-pro filter and Ha extracted from a duo narrow-band l-eXtreme. I had to fight with pretty ugly gradient on both stacks, and could not  achieve that in Pixinsight; instead I used the light pollution removal tool in APP and all the gradient was gone. It's been a while I wanted to give another try at M31 which was my first ever images object.
