 Located just over the "handle" of the Teapot shaped constellation of Sagittarius, this very bright 5.2 magnitude globular cluster is one of the finest in the southern skies. With a diameter over half a degree, this object spills out of the eye piece of my Newtonian telescope with countless thousands of individual stars averaging around 10.7 magnitude each. While this image cannot convey the spectacular beauty we see in the eyepiece, it does show the colorful star rich field and the smaller globular cluster NGC6642 to its upper right (North is up here) a 9th magnitude object with dim 16th magnitude stars spanning only 6 arc minutes.
