Astrometry at the RTT150 telescope within the international collaboration between KSU (Russia), TUG (Turkey), and NAO (Ukraine)

Abstract

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.
