Abstract
In 1962 a photographic vertical circle (PVC) for determining absolute declinations was designed and constructed at the Pulkovo Observatory under the supervision of Prof. M.S. Zverev (Zverev, M.S., 1960). The Maksutov meniscus cassegrain system (D = 200 mm, f′ = 2000 mm) was used for the first time in astrometry. Its construction is symmetric and it is automatically operated. In 1963–1966 the declination observation of bright and faint stars of the southern hemisphere was made with this instrument (Zverev, M.S. et al., 1966). At present after the reconstruction the PVC has been used again for determination of absolute declinations (Bagildinsky, B.K., Usanov, D.S., Smirnov, B.N., 1978).
