NGC 104 is a about 13,000 light years away in the constellation of Tucana. It's diameter is around 120 light years and it's dominated by old red giant stars.
Next to Omega Centauri (NGC 5139) 47 Tuc, as it's most commonly known, is the second largest and brightest globular cluster in the southern sky.
It's characterised by a very bright and dense core.

This is quite a deep, wide angle image. The small clusters on the left, right and bottom right are globulars associated with the Small Magellanic Cloud, part of which can be seen in the lower right corner of the image.
