The MAHIS is the L.A. Sukharev meridian automatic horizontal instrument. It has all the advantages of the Pulkovo HMC and is devoid, or nearly devoid, of its disadvantages. A scheme of the MAHIS includes a flat mirror of D = 300 mm and two immovable horizontal tubes of D = 190 mm, focal length 8000 mm. There is a pavilion for the central unit and 2 roofed pavilions for eyepiece parts of the tubes. The MAHIS is provided with an automatic registering device, a system for meteorological data collection, and is computer controlled. The work on this telescope is being carried out at the Pulkovo, Kazan and Nikolaev observatories. The expected precision of the instrument is ±0.″05 in both coordinates with respect to systematic errors.
