A rather out of place object in a constellation filled with tens of thousands of galaxies, this globular cluster displays the classic blue core and yellow supergiants seen in many other much brighter objects. This object is a dim 9.5 magnitude and the brighter stars average about 17.8th magnitude. It is not a large object at 5 arcmins, but still presents a beautiful object for imaging in amateur telescopes. The 8th magnitude star on its eastern edge makes the cluster an easy to find visual target. Processing: RGB data was summed for a "Synthetic Luminance" and curves applied to expose the core properly. RL deconvolution had to be used to remove the effects of seeing on an object that is relatively low in our sky.
