Located in the constellation Ophiuchus this rather loosely packed globular cluster was once thought to be a tightly concentrated open cluster.

This image was taken as a test of the new Lodestar autoguider and TS-OAG9 off axis guider combination mounted on the 190mm Mak-Newtonian. Conditions were poor...full moon, hot hazy skies, but the test seemed to be a complete success. The Lodestar easily located several guide stars with 1 second exposures in PHD. The TS-OAG9 worked very well with the light weight Lodestar guide camera, resulting in only a 2 pixel image drift over the imaging session.
