Description

Sometimes having a wider field of view, such as the one afforded to me by my Explore Scientific ED102 Refractor, has its advantages. This is one of those cases: not only was I able to capture two globular clusters in the same field of view, but the two objects are also very different from each other.

Messier 53, also catalogued as NGC 5024, is at the left side of this image. It is one of the more outlying globular clusters, residing at a distance of approximately 58,000 light years from Earth and approximately 60,000 light years from the Galactic Center.

On the right side of this image is a much more loosely bound globular cluster, NGC 5053, which lies approximately 53,500 light years from Earth.

Finally, we have the galaxy PGC 46161, which is just down and to the left of NGC 5053.
