Description

The visibility of a secondary radio image of 3C 303a caused by gravitational deflection by the N galaxy 3C 303b is discussed. Failure to observe such an image would place a limit on the core mass of 3C 303b which, if unreasonably low, might be incompatible with a cosmological origin for the red-shift of 3C 303a
