M57

The Ring Nebula

M57 is about 2,000 light-years away in the constellation Lyra. This is a planetary Nebula which is the expanding remains of a sun like star that has cast off its outer layers and become a White Dwarf. This target is not best seen with such a wide field rig but I hope to get closer and higher definition views with time.
