Messier 3 (aka M3 or NGC 5272) is a globular cluster in the constellation of Canes Venatici. At 34K lights years from Earth, it is about 8 billion years old and contains about 500,000 stars. Nice.
Clusters really ain't my thang - I took this whilst waiting for something interesting to get into position (i.e Cygnus). It's not in a great position for my unguided kit, particularly being a cluster, so I had to ditch almost half the subs I took, resulting in 31 minutes total exposure. Nice to see a fuzzy in the top right - NGC 5263 apparently :)
