NGC 6514 / M20 - Trifid Nebula

I've spend good few hours processing this, being an HSO source, there are so many ways colors could go in one direction or another (right or wrong :)). Having had previously worked on Trifid Nebula (in RGB) I almost certainly wanted my first version here in HSO to be a good mix of blue and red. Also following the first TL webinar (again thanks Nik for the great presentation), I am now more careful with how far the black toning of the background is. I've also worked for the most part of the processing separately on the starless version and the stars layer, separated early on and merged again later. There were a few horizontal (mostly) and some vertical issues to deal with too, as well as I've brought back the resolution higher (starting from the BIN2 CHI-1 CMOS).

It's very likely I'd come up with some more color versions (as I already have some PixInsight outputs I've prepared last night, just for HSO palette variations and tweaks), and I think one of them would be more greenish, as despite scientific knowledge about what colors and wavelengths get emitted from space, in false color, green looks good :) So more posts later on.

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum-Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula (the relatively dense, reddish-pink portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance, also designated Barnard 85) [Wiki]
