Second version of combining the full-color version from KGO (3 hours) and the narrowband version from Sochi (about 4 hours). I tried to do it "properly," with continuum subtraction and other clever math. Well, overall it turned out so-so. But that's where my powers end... And the accumulated data for something more serious is still a bit too little.

First rough combination of the full-color version from KGO (3 hours) and the narrowband version from Sochi (about 4 hours). Just a median stack combination in Siril. Properly, this is done differently... I'll get to it later on long winter evenings ;)
