Description

Sadr (Gamma Cygni) sits at the centre of the large asterism known commonly as the Northern Cross that makes up the constellation of Cygnus.

Just to the east (left) of Sadr, is the Butterfly Nebula, IC1318. This actually sits much further away from us than Sadr at ~5000 light years (Sadr is about 750 ly distant). The nebula appears split into two by a dark dust lane running E-W, catalogued as LDN 889.

3h40m total exposure (5min subs) with HDR Composition for bright stars (25x30sec).
