A catalogue of positions and proper motions of 58483 stars (Pul-3) has been constructed at the Pulkovo observatory. The Pul-3 is based on the results of measurements of photographic plates with galaxies (Deutsch's plan). All plates were taken using the Pulkovo Normal Astrograph (the first epoch is in the 1950s and the second epoch is in the 1970s).

The Pul-3 catalogue contains stars of mainly 12 to 16.5 mag in 146 fields with galaxies in the declination zone from $-5^\circ$ to  $+85^\circ$. The Tycho-2 has been used as a reference catalogue.

The mean epoch of the Pul-3 is 1963.25. The internal positional accuracy of the Pul-3 catalogue at the mean epoch of observations is $\pm$80 mas. The accuracy of the proper motions is mostly within $\pm$3 mas/yr to $\pm$12 mas/yr. Comparisons of the Pul-3 with Tycho-2 and ARIHIP have been done at the mean epoch of the Pul-3. The Pul-3 external positional accuracy relative to Tycho-2 is $\pm$150 mas.
