Husband's Astrophotography--The Ring Nebula


This was hubby's best picture yet. It's taken through the telescope. The image is of the Messier Object 57, or M57 as listed in sky charts. It's an example of planetary nebulae--fuzzy images earlier astronomers thought might be planets. Better images helped astronomers realize their error, though they're still referred to as planetary nebulae. Not only can you see the color and the ring, but there's the hint of the inner star there as well.
The Ring Nebula (also known as the Messier 57 or NGC 6720) is located in the constellation Lyra. It is among the most well known and recognizable examples of a planetary nebula.
