This wispy nebula is the result of a supernova that occurred roughly 7000 years ago in the constellation Cygnus. This is a small portion of the large structure called the Cygnus loop. I've always been a big fan on these ghostly looking stellar formations.
It's not false color, if that's what you're asking. With narrowband photography it allows you to capture more colors from specific wavelengths to bring more of the natural color of the different gases in the nebula.
