M13 Globular Cluster

We rented a lens for the upcoming weddings Lisa has in September and I put it to use, pointed skyward. This was pretty exciting for me as this is the best I have been able to do on a deep sky object. Messier Object 13 is not visible to the naked eye but was quickly visible when I saw the first shots. This Globular Cluster contains several hundred thousand stars. This is really amazing because in the picture it looks like one bright object. The below images were created by a composite of over 50 total images (17 "Light" Images) stacked with Deep Sky Stacker to remove noise. The actual picture frames were 3 second exposures, f2, ISO 1600, 135mm.
