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. |
