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. Image galleryReferences1. ^1 {{cite simbad|title=IC 1318|accessdate=8 January 2019}}
