47 Tucanae

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

With an apparent visual magnitude of 4.9, the cluster is visible to the naked eye—and was therefore given the designation of a star in early star charts. It's considered one of the finest clusters 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): binoculars.

The vast nebulous oddly-shaped nebulosity known as the Small Magellanic Cloud is the smaller of two such ‘clouds’, the other the Large Magellanic Cloud in Dorado; the two are joined by a star-forming region known as a bridge of gas.

These two are the nearest galaxies to ourselves at about 200,000 light years each. The Small Magellanic cloud is visible to the naked eye although the listed apparent magnitude of 2.7 is deceptive. Large telescopes are needed to resolve star clusters and nebulae. Several million stars make up the galaxy.
     Long thought to be a satellite of the Milky Way, recent studies with the Hubble Space Telescope cast some doubt on that thought, as the two clouds' velocity through space may be too fast for the two to orbit the Milky Way.


Now if you place theta (centred in the present view) on the southwestern edge, you'll have lambda centred with kappa on the eastern edge. Both lambda and kappa are fine binaries:
      lambda (DUN 2): 6.7, 7.4; 82º, 20.4".
      kappa1 and kappa2 AB: 5.0, 7.7; 319º, 4.8".
