B33 The Horsehead Nebula
B33, also known as the Horsehead Nebula, is an extremely faint emission nebula and a dark nebula interacting to form what is known as the horsehead, as well as the "flame" nebula to its north east.  The horsehead is formed as a result of the dark intersteller dust being moved about by intersteller winds and forming what is easily distinguised as a horses head.  This widefield photograph clearly shows the horsehead and the flame nebulas, both of which are red emission nebulas, which get their glow from the glow of hydrogen gasses.  For more information about this nebula, click here.
