      Description

      60*5 minutes of 3nm Ha

      114*5 minutes of 3nm O3.

      Shot with a ZWO ASI1600MM-Cool and a Canon 300/4L IS tele lens. The lens suffers from bad star shapes in the corners but I managed to get it decent anyway. Didn´t want to stop it down from f/4 either.

      Combined as a semi-RGB (or what to call it) from R=Ha, G=70%O3+30%Ha, B=O3. Processed it as LRGB using a combined Lum from 60% Ha L and 40% O3 L.
