We have measured accurate celestial coordinates for 4741 extragalactic objects, primarily drawn from a list of MCG galaxies with no recently published accurate positions. The standard deviations in the new positions depend slightly on the measurement method but are on the order of 1.0" to 1.2". Standard deviations in the original MCG positions are confirmed to be at the 1.5′-2.0′ level. These new positions were integrated into NED in 1997 December.
