Globular Cluster M15

Located about 33,600 light-years away within the constellation Pegasus, Messier 15 is a globular cluster – a tight, ancient ball of stars on the outskirts of our galaxy. The Milky Way is surrounded by many such clusters; this one’s special because it’s known to host a rare intermediate-sized black hole at its center, and it is one of the densest globular clusters our galaxy has. These stars are between 12 and 13 BILLION years old.

Imaged using my new ZWO ASI2600MM Pro camera, through RGB filters, with 60 second sub-exposures. Total exposure time was 1.5 hours. Globular clusters are relatively bright objects, and a good choice when you only have a few hours of clear skies to work with.
