Description

This was meant to be a Ha-RGB-OIII image, but due to software issues I was able to collect only a single frame in OIII. Nonetheless, to my surprise, the end result is not bad. Most of the luminance comes from Ha, chrominance obtained with the recipe R=Ha; G=1.5*Ha*OIII; B=OIII. The colors of the star field come from a previous attempt using a DSLR (Canon 7D Mark II) with the same optics.
