M57 (NGC 6720) is a mag 9.0 planetary nebula in the constellation of Lyra. This is one of the first images from my new roll off observatory in New Ringgold, PA. Thanks to Chris for his expert processing, which brought out the faint halo around this planetary nebula that we noticed when we started working with the images.
