Omega Centauri (NGC 5139) is without a doubt the finest globular cluster in the night sky. Located in the Southern constellation, Centaurus, the magnitude 3.7 cluster contains over a million stars. It is brighter and more massive than many dwarf galaxies, and spans an area larger than the full moon. The cluster was discovered by Edmont Halley in 1677.

NGC 5139's Southern location (declination -47° 29s) allows obseving from only the Southernmost US states. It is easily visible by naked eye and looks impressive in binoculars. In a modest telescope, the view is breathtaking with countless stars resolving.

This image was taken from the Texas Star Party in May, 2005 (the cold rainy year).
