Sadr region in Cygnus constellation

---

The Sadr Region in the Cygnus refers to the hydrogen emission nebula surrounding Sadr (Gamma Cygni) in the cross of the constellation Cygnus. In this area of the night sky, you will also find even more deep-sky astrophotography targets such as the Butterfly Nebula (IC 1318), and the Crescent Nebula (NGC6888). Sadr, a supergiant star, has 12 times the mass of our Sun and about 150 times our Sun’s radius. IC 1318 is considered to be the diffuse emission nebula surrounding Sadr.
