Abstract : The testing of a unique optical telescope 96.7 meters long and 400 millimeters in diameter, which is located in an underground tunnel, has been completed at the Main Astronomical Observatory of the Academy of Sciences of the USSR. Placed on 18 reinforced concrete foundations and cemented in over half its diameter, this telescope now allows astrophysicists to study molecular absorption spectra, which is important for spectral investigation of the atmosphere of Venus, Mars and other planets.
