Globular Cluster M5
The Globular Cluster M5 resides 24,500 light-years away in the constellation Serpens.   At an age of 13 billion years, it is one of the most ancient globular clusters known, forming only a few billion years after the Big Bang.  M5 is one of the 160 globular clusters known to reside in a spherical halo around the Milky Way's galactic center.  M5 is one of the larger globular clusters,  containing about 100,000 stars within a diameter of 165 light years. 

This image combined 30 minutes luminance exposures with 9 minutes of green and 15 minutes red and 12 minutes of blue exposures.  An ST10XME camera was used through a TEC 140mm refractor at my new observatory.
