Last night I got more H-alpha light and O-III and S-II channels.
-
Two color chemes, HST Palette as S-II=Red, H-a=Green and O-III=Blue. Second image is in natural colors composed from narrowband data. Channels are balanced so, that image match to visible spectrum, H-a + 24%S-II=Red, O-III=Green and O-III + 15%H-alpha=Blue.
