This is the most complex image-processing procedure I've ever performed. The idea was to capture the Andromeda Galaxy as a two-panel mosaic. The reason why I decided to do it was that the whole galaxy doesn't fit onto my APS-C sensor when attached to my refractor. As the galaxy contains starforming regions which are rich in H-alpha, I combined LRGB with Ha. This way I obtained over 27 hours of data. The whole imaging consisted of 10 nights plus 1 night wasted due to high haze or clouds. However, considering local conditions, I think it took 40 hours or more.

Great image from anywhere let alone bottle 9

[Vroobel]

Thanks, that's nice. 😊
The Bortle 9 caused pain when I was fighting with the background. I'm still not too happy with it. 😉
