The Sadr region, or IC 1318, is the diffuse emission nebula surrounding Sadr or Gamma Cygni. Sadr lies in the center of Cygnus' 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.

NGC 7635, also called the Bubble Nebula and Sharpless 162, is a H II region[2] emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7[2] magnitude young central star, the 15 ± 5 M☉[4] SAO 20575 (BD+60 2522).[7] The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.[7] It was discovered in 1787 by Friedrich Wilhelm Herschel.[6] The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses
