The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is a diffuse emission nebula that surrounds Sadr (y Cygni) at the center of the cross. The Sadr Region is one of the surrounding nebulous regions, along with the Butterfly and Crescent Nebulae. In addition to the emission diffuse nebulae, it contains several dark nebulae. This is the first time I've used the PixInsight narrowband normalization process feature in HOO.
