Globular Cluster in Sagittarius 

View larger image

With binoculars, this cluster can be seen as a fuzzy ball just above the dome of the Sagittarius “teapot.”  It is probably my favorite globular cluster.  It is easy to resolve with a medium-sized telescope, and with the large aperture of my 18-inch Dobsonian, it literally fills the eyepiece field with stars.
