Imaged February 6th, 2016 from Rancho Hidalgo (Animas, New Mexico) with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.
At the urging of another local imager, I decided to attempt Omega Centauri from 32 degrees North latitude where it was between 8 and 10 degrees above the horizon. Unfortunately, there were also some thin clouds during the only time I had to image it before sunrise. Iâ€™m amazed at the result.
Omega Centauri (NGC 5139, Caldwell 80 and others) is the largest globular cluster in our galaxy. It is estimated to contain 10 million stars. Shining at a bright 3.9 magnitude, it is located approximately 15,800 light-years away in Centaurus.
