Globular Cluster in Serpens

View larger image

Messier 5 is a superb object, one of the brightest globular clusters in the sky. It is located in the head (west) end of the constellation Serpens, and is well placed for viewing in the late spring and summer months.

The stars around the edges of this dense cluster can be resolved in even small telescopes, and its central core is very dense and bright. The view through telescopes with apertures of 10 inches or more is truly spectacular, with hundreds of stars visible.
