Description

I had to work very hard in Pixinsight to remove heavy noise and strange colors from most of the frames using Pixinsight.
I also had (and still have) problems to dither with APT. So, I'm not so satisfied with result. Anyway.....it was just a usual night collecting starlight :-) ps the picture is cropped.
