SVX102T - Wolf Rayet 134

Mitchell Davis captured this surreal shot of Wolf Rayet 134 in Cygnus with his SVX102T. This variable Wolf Rayet star rests approximately 6,000 light-years away from Earth in a shell of hydrogen which is thought to have previously been swept up by gas, dust and cosmic rays. The shell is over forty parsecs wide containing around 1,830 solar masses of hydrogen.
