| Description: | |||||||||||
| An often overlooked globular cluster due to its proximity to the larger globular M22. In binoculars, M28, M22 and the 3rd magnitude star Kaus Borealis form a nice-looking triangle in the sky. M28 itself is a bright globular cluster showing an extremely condensed center surrounded by a diffuse outer halo where some brighter members can be resolved. M28 contains a "millisecond pulsar", a neutron star which rotates several hundred times per second. | |||||||||||
