IC1318 “Sadr Region”

The Sadr Region is a mosaic of 2 Ha images of 12 and 14 frames of 1800 sec of exposition time for a total of 13 hr, with the FSQ telescope and the QHY90A CCD, taken in June 2016.

The Sadr region, or IC 1318, is the diffuse emission nebula surrounding Sadr (γ Cygni) at the center of Cygnus’s cross. The Sadr region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.

Sadr itself has approximately a magnitude of 2.2. The nebulous regions around the region are also fairly bright.
