Eastern Veil - Origin 25 minutes integration using nebula filter from a bortle 7 location with moon up.
Post-processed in the following way:
TIFF master imported into Siril for a photometric color calibration. Then file exported as TIFF again.
Color-corrected TIFF imported into Affinity Photo for processing including steps for separated starts from nebula, stretching, noise reduction, some background subtraction, cur adjustments, star recombination, etc.
