Description

Disappointed with the attempts from previous years, I wanted to finally capture M31 properly so I can move on to other targets next year. 

I postponed the post-processing for months as I know mosaics can be hard work, I had >50h of data (~800 subs) under varying conditions and expected issues with flat calibration. I ended up using about 36h of data, 8h RGB, 8h luminance and 20h of Ha.

This was also my first experience with Russel Croman's Blur-, Noise- and StarXterminator tools. I'm excited about the quality of the adjustments and also the speed of execution (especially since I got CUDA working). They are game changers for me! 

Shot in August, September and October 2022.
