Two glowing wings

​

The supergiant star Gamma Cygni is located in the centre of the North Cross, in the famous constellation Cygnus. Known by its proper name Sadr, the bright star is located in the centre of this beautiful HII region with a complex of stars, dust clouds and glowing nebulae along the plain of our Milky Way. The field of view extends over 3 degrees (six full moons) in the sky and includes the emission nebula IC 1318 and the open star cluster NGC 6910. formed like two glowing cosmic wings separated by a long dark dust alley, IC 1318's popular name is understandably the Butterfly Nebula. Some distance estimates for Sadr are around 1,800 light years, while the estimates for IC 1318 and NGC 6910 are between 2,000 and 5,000 light years.
