IC 5070 Pelican Nebula

Cygnus

                                                                                                           

 

The Pelican Nebula is an emission nebula located in the constellation Cygnus and is separated from the adjacent North American Nebula (partially visible on the left side of the photo) by a broad band of light-absorbing dark clouds. The Pelican is part of a large cloud of hydrogen gas that is excited by stellar energy and then emits its own light at the characteristic red wavelength of hydrogen-alpha (Ha) at 656.3nm.
