Narrowband (HOO) processing of this interesting emission nebula located in Constellation Cygnus at the distance of app. 5000 light years from the Earth. An unusual type of Wolf-Rayet star is located in the nebula center causing ionization of hydrogen, oxygen and other gases and consequently the light emission. Vast clouds of hot, ionized gas (mainly hydrogen) are present around the nebulosity.
