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. It was discovered by William Herschel in 1792. [2]

It is in the center of the Crescent Nebula. Its age is estimated to be around 4.7 million years and it is nearing the end of its life. Within a few hundred thousand years, it is expected to explode as a supernova. [8] According to recent estimations, WR 136 is 600,000 times brighter than the Sun, 21 times more massive, and 5.1 times larger.
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.
The Soap Bubble Nebula, Ju 1 (also known as PN G075.5+01.7) is a planetary nebula in the constellation Cygnus, [4] near the Crescent Nebula (NGC 6888). The nebula derives its name from its symmetrical spherical shape which resembles a soap bubble .
English: An image of the emission nebula NGC 6888, also known as the Crescent Nebula, in the constellation Cygnus. This object is approximately 5000 light years distant and 26 light years in diameter and is formed by high velocity stellar wind from the central star WR 136 colliding with gas previously shed from the star.
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.
