First imaging session in 2026. Winter this year has had no clear weather... It was windy.

Processing in Siril 1.4.2 using scripts: AutoBGE (background), SyQon [Prism (noise), Starless (star separation)], VeraLux [Alchemy (narrowband palette), HyperMetric Stretch (histogram work), Star Composer (stars+nebula)]. For the stars, the NB_2RGB script was used (to give the stars a more natural color based on frames taken with dual-band filters).
