M15 Globular Cluster

Messier 15 (M15) Globular Cluster hovering out in the blackness. Also known as NGC 7078, M15 is a densely packed cluster of stars in the constellation Pegasus. It is 33.6 light years away and over 13 billion years old.

 

This image was from my first session putting the new telescope through it's paces. This was done on an Alt/Az mount (not equatorial), so field rotation is present during the exposure. Star trails are evident with even this short 30 second exposure. 300 second exposures were hopelessly streaked. I also am thinking I need to collimate the optics since it was shipped halfway across the U.S.!
