γ Cygni Nebula Region

 

Gamma Cygni Nebula Region

 

The third-brightest star of Cygnus, called γ Cygni or Sadr (the bright star at the center of the photograph), is surrounded by a huge complex of emission nebulosity. The nebula is excited by young, hot blue-white stars and separated by dark nebulae into at least five major parts. The brightest of these parts is IC 1318, the bisected nebula region east (left) of γ Cygni which is named the Butterfly Nebula because of its two-winged appearance. The total magnitude of the nebula complex is probably fairly high, but its light is spread out enough to make small parts of it dim.

Another prominent member of the γ Cygni nebulosity is NGC 6888, the small Crescent Nebula three degrees south and slightly west of Sadr (a small arc of nebulosity).
