M6 - The Butterfly Cluster

The Butterfly Cluster (M6 or NGC 6405) is an open cluster of stars in the constellation of Scorpius gets its name from a vague resemblance to a butterfly.  I don't see it though.  The cluster is around 1,600 light-years from Earth and is approximately 12 light years across (source: wikipedia).

This was  getting pretty low and I wasn't sure if I was going to be able to image it at my location.  It came through pretty well with hints of nebulosity near the upper portion of the image.  I think getting the nebulosity is due to the modification of the T3i that Hap Griffin performed on it last year. 

Messier image 94, only 16 more to go...
