Luminance – 8x300s – 40 minutes – binned 1×1
RGB – 2x300s – 10 minutes each – binned 2×2

70 minutes total exposure

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. I’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.
