Here's how hydrogen looks with an adequate and simple full stretch. Due to the contrast between the white and black background, it stands out more than in color, of course) But I'll make another version LRGBHa with a maximally stretched background for likes =)Don't forget to look closely at the nebulae in the "rings" of the galaxy. They deserve far more attention.I'm not sure I integrated two different stacks correctly, but the noise, as I wrote earlier, decreased by a whole 1.5% =D By the way, this is already Drizlle 2x
