M-75
M-75 is a very small and compact globular.  It's smaller and dimmer than M-13, but still offers a nice view. If you can see Capricornus and Sagittarius, you should be able to see M-75, but it may require a six inch scope, depending upon your skies.  M-75 is far south and can be a difficult object for observers in the USA.

The low altitude of M-75 from my location makes it a difficult object.  Seeing is usually poor and the dimmer regions of the cluster get lost in light pollution.
