Globular Cluster in Sagittarius
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.
