The Ring Nebula M57 in Lyra

The RIng Nebula M57 JPEG

The Ring Nebula in the constellation Lyra is the result of a star exploding and throwing off a cloud of gas.  We see it as a ring (with what’s left of the star in the middle).  This object is comparatively small.  (In terms of apparent size M31 (below) is about 6 “Moons” long in its entirety,  the ring is roughly the same size as a medium sized crater on the moon!).  Bizibilder thinks it is a rather pretty object!  It is decidedly green/blue to look at.

Techie: 22 Minutes of exposure, ISO 800, 200mm reflecting telescope.
