Description

This is a mix of H-alpha and OIII data, which I used for my luminance of the Crescent Nebula (see https://astrob.in/369986/0/). Often you don't get a significant increase in details, if you add informations from the OIII images in addition to the pure H-alpha data. The Crescent Nebula, on the other hand, offers a lot and shows some great improvements in the outer areas by doing this. Hope you like it :-)
