NGC 104 – Globular Cluster 47 Tuc

Description of object:

47 Tucanae, a globular cluster in the southern constellation Toucan, is after Omega Centauri the second brightest object of its kind in the sky. It is also possible to see it with the naked eye. In contrast to Omega Centauri, 47 Tucanae has a much brighter center, making it necessary to take some pictures with shorter exposure times.

The diameter of the cluster is approximately 120 light years and it contains, according to calculations, roughly 700000 times the mass of the sun which is divided between more than 1 million stars. With a distance of 16.700 light years, the cluster covers about the same amount of area in the sky as the moon.
