Description

M53 Globular Cluster

M53, appearing a little to the top-right of the center of the image, is a Globular Cluster that measures about 220 light-years across and lies about 58,000 light-years from Earth. It contains over 500,000 stars, and is one of the more distant globulars in our galaxy. M53 is somewhat unusual in the fact that it has a relatively high number of "blue stragglers", stars that have a blue tint due to interaction with other stars. The object to the bottom-left of M53 is NGC5053, an irregular globular cluster. NGC5053 contains about 3,500 stars and is obviously less densely packed.

Description: 1. Fixed gradient in far lower-right that I didn't see at first.
2. Increased color saturation before combining RGB with L to improve color of faint stars.
