Gum 68 / Sh2-13 / RCW 133 – Emission Nebula in Scorpius – HSS w/RGB Stars v1

Took me a while to create something with presentable colors from the narrowband data of this obscure nebula in Scorpius, the previous H-alpha black and white version was easier.

This is a bicolor image with R=H-alpha, G=SII, B=SII and mainly H-alpha with a bit of SII used as luminance, plus calibrated RGB stars screened on-top.
