Wilder T4 astronomical theodolite
"Wilder T4 astronomical theodolite" is a high-precision angle measuring instrument designed for astronomical observation. It is mainly used to determine the position, trajectory and atmospheric refraction of celestial bodies (such as stars, planets, comets). In its name, "Wild" usually refers to the manufacturer of traditional astronomical instruments in Germany or Switzerland. "T4" is the model code and represents its technical iteration version. "Astronomical Theodolite" defines its core function-to realize precise measurement of azimuth and altitude of celestial bodies through telescope and dial system.
