Rosette Nebula in SHO Palette. 22 hours of #NBOSC exposure on 2025-11-24>12-11 under Bortle 7 skies from Austin, Texas, rendered in a SHO palate. I added 12 hours of L-Synergy Sulfur II and Oxygen III data to my Thanksgiving image, with its 10 hours of L-Ultimage Hydrogen alpha and Oxygen III data. Unlike my first two SHO images made under dark skies, this is my first SHO image made under Austin's light polluted Bortle 7 skies. I'm pleased with these results.
