Description

For the final version i added bias frames, flats and four more light frames.

I was able to recover more of the faint nebula and used GIMP g'mic filters to blur the sky. And i finally was able to get rid of some strange star colours.

I didn't used the best flats... it was more about vignetting and not dust (the WO RedCat 51 has very low vignetting ). All the dust spot didn't effect the galaxy... they were scatterd all around it.

And finally polar alignment wasn't quit good. Some screw got loose i realized after i finished taking photos. There are little star trails. In post processing i was able to reduce these and get some round stars. Nevertheless, i am quite happy with the final image!
