Description

This is my first HaGB composite image. First I created an RGB Image with my UHC filter and on the next night I used my L-extreme dual narrow band filter to capture Ha and O3.
I used Siril for the Pre-processing. This resulted in 5 layers (R, G, B, Ha, O3) which I combined in Photoshop as Ha, G, B.
