Comments: Discovered by Abbe Nicholas Louis de Lacaille on September 14, 1751. NGC 104, better known as 47 Tucanae, is the second largest and second brightest globular cluster in the skies, outshone only by another southern globular, Omega Centauri (NGC 5139). As its name "47 Tucanae" indicates, this object was first cataloged as a star and numbered the 47th in Tucana. Although a conspicuous naked-eye object, it is situated so much south at its declination of -72 deg, that it was not discovered as a deepsky object before 1751, when Abbe Lacaille cataloged it in his list of southern nebulous objects. Next to observe and catalog it were James Dunlop in 1826, and John Herschel in 1834.The stars of 47 Tucanae are spread over a volume nearly 120 light years across. At their distance of 13,400 light years, they still cover an area of the sky of about the same apparent diameter as the full moon, about 30 minutes of arc. Globular cluster 47 Tucanae is approaching us at roughly 19 km/s (SEDS). NGC104 has a tight core, making it difficult to resolve. 
The Small Magellanic Cloud (NGC292) can be seen just entering the field in the top right corner. A small globular cluster NGC121 is seen just "below" NGC104. This globular cluster actually belongs to the Small Magellanic Cloud, while NGC104 belongs to the Milky Way Galaxy. They just happen to line up conveniently.
