Visibility IV / V

Tucana 47, or NGC 104, is a well-known, bright, and spectacular spherical array in the Small Magellanic Cloud. The set is bright and compact and its brightness increases towards the core. The set seems strongly granular, meaning that the individual stars in the set are just on the verge of separation.
