I shot this not too long ago of the M13 star cluster.
From where I am located, it was not visible to the unaided eye.
M-13 is a Globular star cluster in the Constellation Hercules. It contains several hundred thousand stars, and is approximately 25,000 light years from earth.
It's estimated the cluster has about half million stars and is about 100 light years diameter.
It's believed the age of M13 is about 14 billion years.
