NGC6540 - Djorgovski 3

Loftus, NSW

One of the hidden globular clusters - NGC6540. It was only fairly recently reclassified as a globular after cataloguing by Djorgovski in 1987. A 1994 paper by Bica et al puts this cluster at about 11,500 light-years away, and the mass of Galactic Bulge stars in the background closer to 24,000 light-years distant. 100% crop.
