In June 1764, this star cloud was catalogued by Charles Messier as a large cluster. It is visible to the naked eye but apparently was not mentioned by any observer prior to Messier. M24 is about one degree by two degrees in size. This rich cloud of stars looks great in a wide-field telescope. M24 is sometimes referred to as the Small Sagittarius Star Cloud to distinguish it from the larger cloud near Gamma Sagittarii.
