On the occasion of its discovery, William Herschel cataloged this globular cluster as H 2.200, indicating that he took it for a "Faint Nebula." His son, John Herschel, listed it as h 3723 in his "Cape of Good Hope" catalog, and included it in his General Catalogue as GC 4364.

NGC 6528 is the fainter of the two globulars shown in our image, i.e. that on the left hand side. The other globular is NGC 6522. Note the dark nebulae just left (east, following) of NGC 6528. Also visible are innumerable stars of the Milky Way, which are visible through a hole or window in the absorbing interstellar matter, which usually blocks such a deep view in that direction close to the Galactic plane and center. This paritular hole is called "Baade's Window."

The image in this page was obtained by David Malin of the Australian Astronomical Observatory, with the 3.9-meter Anglo-Australian Telescope. It is a three-color composite of exposures on photographic plates with different emulsions and filters.
