Gamma Cygni (γ Cygni, abbreviated Gamma Cyg, γ Cyg), officially named Sadr / ˈ s æ d ər /, [11] [12] is a star in the northern constellation of Cygnus, forming the intersection of an asterism of five stars called the Northern Cross.
The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr 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.

NGC 6910 is located half a degree east-north east of Gamma Cygni, also known as Sadr. It may be physically related with the nebula IC 1318 (also known as the Gamma Cygni Nebula) as it lies at a similar distance, behind the galactic Great Rift. Cygnus OB9 is located within the Orion Arm of the Milky Way. Cygnus OB9's dimensions in the sky are 2. ...
Messier 29 or M29, also known as NGC 6913 or the Cooling Tower Cluster, is a quite small, bright open cluster of stars just south of the central bright star Gamma Cygni of a northerly zone of the sky, Cygnus.
Crescent Nebula (Caldwell27) captured by David Rousseau from an urban location in Québec, Canada using Ha and OIII narrowband filters. The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth.
IRAS 20324+4057 is a mixture of interstellar gas and dust that extends a light year in length in the Cygnus constellation, 4,600 light-years away. [2] It is located within the Cygnus OB2 association. [2] It has been imaged by the Hubble Space Telescope and has been nicknamed a "Cosmic Caterpillar", as it resembles a crawling caterpillar. [3]
