Abstract

An idea for a photographic vertical circle (PVC) was proposed by M. S. Zverev in 1960. This instrument was used for the observation of the absolute declination of stars in Chile and Pulkovo. Later in 1980's modernization of the PVC was made. During its modernization fiber optics were used for improving the readings of the divided circle and making it photoelectrical instead of photographical. Therefore the precision of the observations were increased up to 0.05 inches.
