Messier 13, the Great Globular cluster located in the constellation of Hercules. It is one of the brightest and best know globular clusters in the northern hemisphere. The cluster has a diameter of around 145 light years and contains about 300,000 stars.
In this wide field view, many distant background galaxies are revealed.

M15 is a globular cluster located in the constellation of Pegasus. It consists of an estimated 100,000 stars and has a very dense central core having undergoing a core collapse where stars migrate towards the center. It's age is estimated at 12 billion years and is located 33,600 light years away.
Cataloged by Charles Messier in 1764 in his catalog of comet like objects.

M4 is one of the closer globular clusters to Earth at only 7,200 light years away. Located in the constellation of Scorpius, not far from the red super giant star Antares. It is distinguished by an optical bar of stars running through the central part of the core. A relative small globular as globular clusters go with only ten's of thousands stars, it may have been more massive in its past as it's orbit takes it through the Milky Way disk, where it loses stars due to tidal shock.

Nicknamed the Intergalactic Wanderer because it was originally thought not to be in orbit around the Milky Way galaxy. The globular cluster is located 300,000 light years the galactic center, which is further away than the Large and Small Magellanic satellite galaxies of the Milky Way galaxy. If not for the extreme distance, it would be one of the larger, brightest globular clusters visible. It is estimated it takes 3 billion years to complete an orbit around our galaxy.
