NGC 6276 = IC 1239 is a 14.6 likes bright lenticular dwarf galaxy from the Hubble type S0 in the constellation Hercules at the northern sky . It is an estimated 129 million light-years from the Milky Way and about 15,000 light-years across. Together with NGC 6278 , it forms the gravitationally bound galaxy pair Holm 765 .
In the same area of the sky are u. a. the galaxies NGC 6267 and IC 4639 .
The object was discovered by Albert Marth on June 10, 1864 . The objects NGC 6276 , NGC 6277 and NGC 6278 located in this area were noted by different astronomers with different position errors. Dreyer was unable to resolve these discrepancies when creating the catalog, so that Guillaume Bigourdan's observation on June 19, 1887, received an entry in the index catalog under IC 1239 .
