Astrometric observations of 212 large visual binaries are reported. Data obtained with a GG 495 yellow filter on IIaD photographic plates using the Zen astrograph (aperture 20 cm and focal length 2077 mm) of the Osservatorio Astronomico di Brera during 1985-1986 are presented in extensive tables. The potential significance of these measurements for the catalog being constructed for the Hipparcos space observatory is indicated.
