47 Tuc = NGC 104
This Globular Cluster in the vicinity of the SMC, but much closer to us, is visually the second brightest GC, with a strong brightness concentration towards the center. Its integral spectral class is G4, therefore, it appears yellowish. Unlike most other GCs, it contains only a few Blue Stragglers. This image is my first one at Telescope Live.
