OBJECT DESCRIPTION AND IMAGE SESSION

NGC 6624 is a rather small Globular Cluster located at the heart of the constellation of Sagittarius, less than one arc minute south east from Delta Sagittarii (aka Kaus Media) Mg 2.72. Since it is close the Milky Way equator the background is full of stars and hence a nice object to image from my backyard bortle 8 sky. The Globular was discovered on 24 June 1784 by German - British astronomer William Herschel using a 6.2 inches f13 telescope made by himself . NGC 6624 is visible as a hazy spot with a small telescope, and appears as a star-like object with binoculars. Its core appears significantly condensed.
