Description

Rosetta Nebula 

Location: Volcan, Panama (about 4,500')
Camera: ASI071MC, gain 90
Main Scope: RedCat 51
Mount: SkyGuider Pro
Guiding: ASIAIR Pro
Subs: 20 x 120s, 24 x 300s
Post Processing:
APP, Photoshop, Lightroom
I reviewed subs and stacked good ones in APP. Then imported the result into PhotoShop. Made 2 copies as layers, removed stars from one layer using RC-ASTRO StarXterminator so that I could just work on the nebulosity, then later blended the stars back in. Before merging I reduced the brightness of the stars layer. I found that the "Lighten" blend mode in Photoshop gave surprisingly good results with minimal effort.
