SH2-108 Sadr NGC 6910 in HOO

Sadr (Gamma Cygni) is the center star of the Northern Cross and is about 1,800 ly from earth. Its solar mass is 12.11 times that of the Sun, so it is destined to be a supernova someday. The nebulosity and dust clouds that appear to surround it are actually 4,900 ly away, so they do not interact with Sadr. The open cluster NGC 6910 is just to the right of Sadr.
