M57 The Ring Nebula
M57 The Ring Nebula in the constellation Lyra . The nebula is a shell of ionized gas given off by the central star during the final phases of its evolution prior to becoming a white dwarf. It lies approximately 2,300 light years from Earth. The smudge above and to the right of M57 is external galaxy IC 1296.
Although relatively bright the nebula has an angular size of 1.5 × 1 arcminutes. The picture represents the full field in my camera with 11inch @ F7.5 .

Started at Cherry Springs State Park the morning of July 17th, 2015. I ended up getting clouded over by 2:00 AM and only got about a hours worth of data. Completed in Highland Lakes, NJ the morning of July 25th.
