Sadr (γ Cyg) and part of IC 1318 in Cygnus

Gamma Cygni (known by the proper name Sadr) is a supergiant star at the center of the constellation Cygnus. This image shows a big part of an emission nebula, known as IC 1318 (or Sh2-108, or Gamma Cygni nebula), and surrounding this 2.2 mag. star. Left of Gamma Cygni is the young, tightly grouped open cluster NGC 6910. Some dust clouds and glowing nebulae, making the entire nebulosity complex of IC 1318 are catalogued also in Lynds catalogues (see the mouseover annotation). The distance to Gamma Cygni is estimated to be about 1800 light-years, while estimates for IC 1318 and NGC 6910 range from 2,000 to 5,000 light-years.
