This is 6 hours of Ha and Oiii data that I processed from Astrobin public data pool posted by Robert Huerbsch. Scope: AT130EDT. Camera: QHY163m with Astronomik Deepsky 6nm Ha, O3 filters
Frames: 70 x 150s each Ha, O3 at gain 139 and 200.

A synthetic green channel was made with a 50:50 mix of the Ha and Oiii and I aimed at processing the HaOiii data in a way that I imagine looks rather natural and close to RGB.

Thanks a lot for posting your data Robert!
