Description

Astrodarkness is gone so I am digesting the data I collected this season. Here are four HaRGB images of nebulae from the Sharpless-2 catalogue that I caught with my Esprits in February - March. Sh2-207 lies in Camelopardaris and the others in Cassiopeia. The Sh2-207 image also contains Sh2-208 (the small red dot to the left). These nebula were only apparent after collecting Ha and adding it to the RGB data (red channel). Please see the separate posts for more info.
