NGC 104, better known as 47 Tucanae, is the second largest and second brightest globular cluster in the sky, outshone only by another southern globular, Omega Centauri (NGC 5139). As its name "47 Tucanae" indicates, this object was first catalogued as a star and numbered the 47th in Tucana. Because it is situated at declination of -72 deg, it was not discovered as a deep sky object before 1751, when Nicolas Louis Lacaille catalogued it in his list of southern objects.

 The image was taken with a 6 Inches Newtonian Orion Optics UK and a QSI WS 583 riding in a NEQ 6 mount, 100 km north from Buenos Aires Argentina. Total exposure time 150 minutes.
