Description

For the last time, I checked what is possible with my 40 minute dataset. New processing in PS using luminance masks and a better preprocessing of the luminance channel (the IFN).

I also removed the large halos around the stars on the extremely-stretched luminance channel. I think this version has less artifacts compared to the earlier ones.

Still wondering about the blue stars in the lower right. Maybe my lens has some kind of "temperature vignetting" or something else went wrong.
