The Hercules Globular Cluster is found in the Hercules constellation. It is one of the most brilliant clusters visible from the northern hemisphere, containing upwards of 100,000 stars!
Globular clusters such as this one have provided us with a better understanding of stellar evolution, yet they are still rather mysterious to astronomers as they are located in what is called a Globular Cluster Halo that surrounds galaxies.

This image is officially the first light with the Celestron edge 8HD telescope and is the result of relatively little data. Fortunately enough, star clusters don’t require much integration time to produce a nice image, making them great first-light targets.
