 There
            is over 100,000 stars in this cluster, the most famous globular
            cluster in the sky. Gold and blue supergiants dominate this image
            creating a spray of color and light. This object is rated at
            5.8 magnitude, and 20 arcminutes in diameter. Most stars are
            11.9 magnitude, with the faintest members over 15th. In the lower
            left corner is the faint spiral IC4617, a 15.5 magnitude object
            only 1.2 minutes in size.

            
Seeing was very
            bad this night, but transparency was good.
