Messier 57 (Ring Nebula) - Planetary Nebula in Lyra
Messier 57 is a Planetary Nebula in the Lyra constellation. Messier 57 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 8.8, Messier 57 is visible with the help of a binocular with a 60-70mm aperture or a small telescope.
