IC 839 is a galaxy just where Bigourdan observed it, though it has been equated in the past with one or the other of the components of NGC 4851. Bigourdan's position for the IC object, reduced with respect to the GSC position for his reference star, falls within a few arcsec of the GSC position for the galaxy.
