This beautiful emission nebula in Cygnus is the result of a prehistoric supernova explosion, which was not recorded by man. Forming a complete loop some 2 degrees in diamter, the object is too big to fit in the field of the 12.5 inch, so here the most interesting part is seen. The deep hypered tech pan exposure was supplemented with two 45 minute exposures on hypered PJ400 color film to form the final image. Both exposures were made succesful by careful guiding with the SBIG ST-4.
