M57 Ring Nebula April 5, 2012

M57, the Ring Nebula, is a planetary nebula in the constellation Lyra. It is a cloud of cold gas expanding away from a small hot central star that provides energy for the gas cloud to glow. The nebula is relatively easy to find and is visible even with 3-4 inch telescopes. Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 10 x 60 sec exp, IS0 1600.
