Description

This was a strange region to process because of all the reddish-brown dust and dark lanes. In the end i got the best result leaving most of my normal processing steps out of the workflow. leading to:
No DBE, no backgroundcorrection, no color correction, no noise reduction, no masked stretch, no intensity transformations. Leaving just the histogram transformation and a little curves adjustment.

There is not much information to find about the Northern Trifid and all i could find about the meandering dark dust lanes is the designation LDN1482. This text (source APOD) is the best i could find: "But unlike the Trifid, in NGC 1579 the reddish glow is not emission from clouds of glowing hydrogen gas excited by ultraviolet light from a nearby hot star. Instead, the dust in NGC 1579 drastically diminishes, reddens, and scatters the light from an embedded, extremely young, massive star"
