Facts about M57 by Keith Turnecliff

The nebula cannot be resolved in small binoculars and is best seen in 8-inch and larger telescopes. Even smaller telescopes will reveal the nebula’s ring shape, while medium-sized instruments will also show its interior hole.
With a visual magnitude of 14.8, the nebula’s central white dwarf is a difficult target. The best time of year to observe M57 is in the summer months.
The Ring Nebula is one of only four planetary nebulae listed in Messier’s catalogue, along with the Dumbbell Nebula (M27), the Little Dumbbell Nebula (M76), and the Owl Nebula (M97).
