- Zenith_telescope abstract "A zenith telescope is a type of telescope that is designed to point straight up at or near the zenith. They are used for precision measurement of star positions, to simplify telescope construction, or both. A classic zenith telescope, also known as a zenith sector employs a strong altazimuth mount, fitted with levelling screws. Extremely sensitive levels are attached to the telescope mount to make angle measurements and the telescope has an eyepiece fitted with a micrometer. They are used for the measurement of small differences of zenith distance, and used in the determination of astronomic latitude.Other types of zenith telescopes include the Monument to the Great Fire of London that included a central shaft meant for use as a zenith telescope. High-precision (and fixed building) zenith telescopes were also used until about early 1980s to track Earth's north pole position e.g. Earth's rotation axis position. Since then radio astronomical quasar measurements have also measured Earth's rotation axis several orders of magnitude more accurately than optical tracking. NASA Orbital Debris Observatory, which used a 3 m diameter aperture liquid mirror, and the Large Zenith Telescope uses a 6 m diameter aperture liquid mirror are both zenith telescopes since the use of liquid mirror meant these telescopes could only point straight up.".
