Wide-field image of IC1318 in Cygnus
The bright star projected at bottom centre of this image is the supergiant Gamma Cygni (aka Sadr). It is located only 750 light years away and so is not directly associated with the vast emission clouds of the Cygnus complex which are much more distant at 5,000 light years. Above Gamma Cygni and shaped like two luminous wings divided by a long dark dust lane is the nebula complex IC1318 commonly referred to as the Butterfly Nebula.
This image was obtained with my TS60ED F/4.3 APO refractor and illustrates what a great instrument it is for acquiring deep wide-field images of extended objects.
