New version of the Rosette Nebula, this time processed partially with PixInsight. Decided to upload it as a new image rather than a revision of the my last version as they are very different from each other. I like the lightness of this version, looking back on the other version, I see now that it feels very heavy, and somewhat over processed compared to this version. This feels like gas, while the other one almost looks like a thick sludge. Kinda weird to describe an astro image like that but that's how I feel about them.
