The biggest glob in the sky. From Wikipedia: Omega Centauri (ω Cen or NGC 5139) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 15,800 light-years (4,850 pc), it is the largest globular cluster in the Milky Way at a diameter of roughly 150 light-years.[10] It is estimated to contain approximately 10 million stars and a total mass equivalent to 4 million solar masses.[11] Omega Centauri is so distinctive from the other galactic globular clusters that it is thought to have an alternate origin as the core remnant of a disrupted dwarf galaxy.[12] Contents Details: Object: NGC 5139(Centaurus) Exposure: LRGB(5.9hrs) Seeing: Poor Location: Padstow,Sydney,NSW,Australia Telescope: RC10 Mount: MX+ Camera: SXVRH16 Guide: ONAG/ASI 174 Software: AA5/CC
