About C107
Description
NGC 6101 is a loose, sparse globular cluster in Apus, about 47,600 light-years away. It spans about 11 arcminutes and shines at magnitude 9.3, making it one of the fainter Caldwell globulars.
Observing Tips
A small, faint glow in a 6-inch telescope. An 8-inch scope begins to resolve a few outer stars. Its sparse nature means it never looks as impressive as the more concentrated globulars. Best from southern latitudes in winter.
History
Discovered by James Dunlop on June 1, 1826 from Australia. It is one of the least concentrated globular clusters known.
Fun Facts
NGC 6101 has one of the lowest central concentrations of any globular cluster. Studies suggest it may contain an intermediate-mass black hole that has gravitationally stirred the cluster, pushing stars outward and preventing core collapse.
