A 1998 follow-up study using the Russian 6-meter Large Altazimuth Telescope found magnitudes, diameters, separations, morphological types, configurations, and radial velocities.
Opticians are working to remake a flawed 42-ton slab of glass into a first-rate primary mirror for the 6-meter Bolshoi Teleskop Azimutal'ny (Large Altazimuth Telescope) on Russia's Mount Pastukhov.
The scope has two modes of motorized operation: Go To, and what Orion calls "Auto Tracking." The latter simply allows the instrument to operate like a motor-driven altazimuth telescope without the computerized pointing.
