The shooting process lasted from June onward, taken slowly between other targets. There were also days when I photographed under a full Moon, but those frames were not included in the final stack. So, here is the result from the perspective of my still modest experience in shooting and processing.))

Thank you for your attention!

The accumulation is quite substantial, but stacking more than 150–200 frames doesn't make much sense. At least, I don't notice any significant improvement in quality between 150 and 300 frames in total.

Just out of curiosity, I gave it a try. I have about 30 hours of integration on the DsAstro website, so I wanted to see what would come out of it. I also have another 10 hours of data on top of that, but taken during a full moon. Recently, I learned how to stack in FitStacker, so I’ll try stacking all the sessions in it. It seems FS is smarter than DSS, so in theory it should bring out more detail… Probably.
