M3 Globular Cluster

First real test of new IDAS D3 LP filter. An improvement on the older P2 but not massive. Made processing a little easier though.

 

Messier 3 is a globular cluster of stars in the northern constellation of Canes Venatici. It is one of the largest and brightest, and is made up of around 500,000 stars, is about 11.4 billion years old and is about 32,000 light-years away from Earth.
