NGC 2419, often called the Intergalactic Wanderer because of the 300,000 light years distance from our galaxy. Originally not thought to be gravitational bound to our galaxy, it now thought to be in orbit around our galaxy and takes about three billion years to complete one orbit. If not for its extreme distance, it would be one of the brightest globular clusters in the night sky, as it is one of the most massive globular clusters that orbit our galaxy.

Messier 15, one of the oldest globular clusters around our galaxy, estimated age of 12+ billion years, and a densely compacted core due to core collapse. M15 contains an estimated 100,000 stars. Imaged during first quarter Moon.

One of the best known northern hemisphere globular clusters containing around 300,000 stars. Globular clusters are are old objects and M13 is estimated to be around 11.5 billion years old based on the amount of heavy metal contents in its stars. Imaged just before a full Moon.

Messier 4 is a globular cluster located in the constellation of Scorpius. M4 is one of the nearer globular clusters at a distance of 7,200 light years. It was one of the first globular clusters to be resolved as a collection of stars by Charles Messier who added it to his catalog in 1764. A relative small globular cluster as it only contains 20,000+ plus stars. It may have had more stars in its past, but it's orbit takes it through the Milky Way's disk where it could loose stars due to gravitational interactions.

Globular cluster M92, less well known than the more famous M13, despite being one of the brightest globular clusters in the northern hemisphere. It is also estimated to b one of the oldest globular clusters at an estimated 14.2 billion years old.

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.
