IC 1318 is one of the brightest of the emission nebulae within the Cygnus complex, with a diameter of over 100 light years. The bright star at the center of the nebulosity is Gamma Cygni, known as Sadr. Sadr is about 750 light years from Earth, and therefore not connected with the IC 1318 nebulosity.

This image was created from three images each taken through a separate filter, where red = hydrogen alpha (656.3nm), green = ionised nitrogen ( 658.4nm), and blue = ionised sulphur (673.4nm).
