The North American Nebula is an emisson nebula (nebula formed of ionized gases from high-energy ultraviolet photons emitted from a nearby hot star) in the constellation Cygnus. It is approximately 2,590 light years from earth. This image was captured in my backyard with a telescope and dedicated astrophotography camera.
