M20 Trifid Nebula

I worked on Labor Day. I combined R + Ha using a median of 1.5 to avoid noise from hydrogen in the background. Then processed it like a regular LRGB. No masks or star removal, luckily there aren't many stars here. Lately, I only stretch GSH on the background between stars, trying not to touch the nebula itself, or just stretching the darkest parts of the frame. I think I'll revisit this stack later.
