IC1318 NN – Gamma Cygni Nebula (around 37 Cygni)

IC1318, also known as the Gamma Cygni Nebula or Sadr region, is a vast emission-nebula complex in the constellation Cygnus, at an estimated distance of between 4,000 and 5,000 light-years from Earth. This version was modified using the Narrowband Normalization process, producing a colour palette that reveals the details of the nebulosity much more clearly.
