Sh2-115 and Abell 71

Object Sh2-115; Sh2-116; Abell 71
Description A chaotic, but visually dynamic patch of the night sky in Cygnus. This is panel 45 out of 66 in a bigger mosaic project I started in 2018. I think this panel stands well on it's own, and has convinced me that shooting SII might really be worth it for the whole project. Ha and SII from Somerville (Bortle 9); OIII from Oakham (Bortle 5).
