Description

Hydrogen Alpha as red, Oxygen III as blue and Sulfur II as green. I'm still having trouble with coma corrector spacing (it measures correctly, but the coma is terrible), so the image is heavily cropped. I desaturated the magenta in the stars to give them a more natural look.

Description: Revision in SHO. I'm surprised that the stars are now showing more than one color. I might have to stick with the sulfur II, hydrogen alpha and oxygen III mapping to RGB.
