Omega Centauri, also known as NGC5139 or Caldwell 80, is an extremely large globular cluster in the constellation Centaurus, located at a distance of approximately 15,800 light years. Due to its density, it is very difficult to estimate the number of stars, but the number is well into the millions. At Eastman Lake (Latitude 37.219154) this southern sight is EXTREMELY low in the sky, peaking at just 5.9 degrees above the horizon. The strange green mass near the bottom of the image is actually the trees that Omega Centauri was barely above as it moved across the sky.
