Waiting for the clouds to move out on my second of three nights at the 1.5-m telescope on Mt. Lemmon, I took the opportunity to take a few images that I normally wouldn't have time to take. This object is known as the "Ring Nebula", because it is, obviously, shaped like a ring. (Great imagination, we astronomers!)
