Going to have another shot at processing the colour side of this, happy with the synthetic luminance at the moment but I really HATE the stars in it :/ Still trying to teach myself an effective way of desaturating the stars without creating a white ring around the brighter ones. Getting better but not quite. So I have just done a cheap "fix" and saturated the image with a star mask to tone them down a couple of notches
What I personally particularly like about this regions is that it looks like there are so many layers of stuff going on, even though it is a flat 2D image. When you zoom back a bit it does look 3D, I guess it really helps having that blue backdrop with the golden filaments and black dusty regions
Just an FYI, I don't think this regions appreciated being dropped back into an 8-bit format
