M57, the Ring Nebula

M57 is one of the planetary nebulae that shows its best at long focal lengths. This image is one of the first images taken with a Celestron C8 to judge that scope's ability to take such longer focal-length shots

M57 lies in Lyra, and is one of the archetype planetary nebulae. I was aware of this nebula even as a child interested in the sciences, and even then its shape made its name so obvious to me.
