Omega Centauri

Omega Centauri

This spectacular star cluster is located in the constellaton Centaurus and is about 15,800 light-years from Earth and contains several million stars. It is about 12 billion years old. I reprocessed it in Feb. 2012 using the latest version of Images Plus (4.50) which has a nicer version of Digital Development than I was using. The result is better star color and more of the faint stars that I was getting previously.
