Blue Snowball Nebula
The Blue Snowball is a planetary nebula, representing a dying star that has shed its outer layers, similar to the Ring Nebula, Dumbbell Nebula, and Helix Nebula, but more distant.  Through a large telescope, the Blue Snowball appears visually as an oval turquoise gem against a velvet black sky, in the constellation Andromeda.   The Blue Snowball Nebula has been catalogued as NGC 7662 and more recently designated Caldwell 22.

This image combined 30 minutes of red, 27 minutes green and 24 minutes of blue exposures, all unbinned.  An ST10XME camera was used through a Meade 12" LX200R and an AP reducer at my new observatory.
