Nebula in HST-palette, S-II = Red, H-alpha = Green and O-III = Blue
A Grop from the bigger image
H-alpha + 20%S-II = Red, O-III = Green and O-III + 15% H-alpha = Blue
Now I have S-II (Ionized Sulfur) and O-III (Ionized Oxygen) channels, so making fullcolor image is possible
Camera QHY9, Optics Meade LX200 GPS 12" forced to @ f4.65 Guiding with SXV-AO active optics unit 11Hz Filters Baader H-alpha 7nm, 6h, 20 min subs Baader O-III 8,5nm 1h, 10 min. subs binned 3x3 S-II 1h 40, 10 min subs binned 3x3 - Note. a special technique of mine is used to balance weaker channels with Hydrogen alpha.
