We have observed the pair of radio sources 3C 395 and 3C 382 using Very Long Baseline Interferometry in November 1990, simultaneously at 8.4 and 2.3GHz. Through the use of differential astrometry techniques we have determined with sub-milliarcsecond precision the angular separation between these two sources. We have demonstrated the feasibility of differential astrometry for pairs of radio sources separated 6deg on the sky, being the reference source a low luminosity radio galaxy. Successive differential astrometry observations would allow to clarify unambiguously the internal kinematics of the quasar 3C 395.
