47 Tucanae is such a large globular cluster it's gained the label of ‘47 Tuc’. Its official designation is NGC 104.

The cluster is visible to the naked eye (and was therefore given the designation of a star in early star charts) and is considered one of the finest in the heavens, second only to the omega Centauri cluster.

Although thousands of stars make up the cluster, the brightest are only eleventh-magnitude. Thus it takes a medium to large sized telescope to begin to resolve its individual members.

47 Tucanae is found in the same region as the Small Magellanic Cloud (NGC 292), a vast nebulous oddly-shaped region to the south of the constellation: binoculars.
