Abstract

This paper describes the design features of the MAGIS horizontal-type meridional telescope of the Pulkovo Observatory and its operating principle. Questions are considered of the technological and metrological basis for choosing the materials for its subassemblies. The transit circle of MAGIS is intended for differential determinations of the coordinates (right ascensions and declinations) of objects to 17th stellar magnitude on the celestial sphere in the B, V, and R bands of the Johnson photometric system and in the integral sensitivity band of the detector.
