Підтримка:The authors highly appreciate the fruitful discussion with William Thuillot about the GAIA mission and the follow-up programme.
Modern astrometric projects require precise positional measurements of objects down to magnitude 20m–22m. For ground-based observations, this is possible by the use of astrographs with apertures 1 meter or more with precise tracking using long exposures and precise timing. The multifunctional astronomical complex RTT150 (the 1.5-m Russian–Turkish Telescope) is appropriate for such purposes.
