  2. Zenith telescope - Wikipedia

    en.wikipedia.org/wiki/Zenith_telescope

    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

    en.wikipedia.org/wiki/Zenith

    A zenith telescope is a type of telescope designed to point straight up at or near the zenith, and used for precision measurement of star positions, to simplify telescope construction, or both. The NASA Orbital Debris Observatory and the Large Zenith Telescope are both zenith telescopes, since the use of liquid mirrors meant these telescopes ...

    en.wikipedia.org/wiki/Large_Zenith_Telescope

    The Large Zenith Telescope (LZT) was a 6.0-meter diameter liquid-mirror telescope located in the University of British Columbia's Malcolm Knapp Research Forest, about 70 km (43 mi) east from Vancouver, British Columbia, Canada (north from Maple Ridge). It was one of the largest optical telescopes in the world, but still quite inexpensive. The ...

    The Experiment to Detect the Global EoR Signature (EDGES) is an experiment and radio telescope located in a radio quiet zone at the Murchison Radio-astronomy Observatory in Western Australia. It is a collaboration between Arizona State University and Haystack Observatory , with infrastructure provided by CSIRO . [ 1 ]

  8. Meridian circle - Wikipedia

    en.wikipedia.org/wiki/Meridian_circle

    To determine the zenith point of the circle, the telescope was directed vertically downwards at a basin of mercury, the surface of which formed an absolutely horizontal mirror. The observer saw the horizontal wire and its reflected image, and moving the telescope to make these coincide, its optical axis was made perpendicular to the plane of ...

    The Royal Society for the Improvement of Natural Knowledge by Experiment [g] was founded in 1660 and given its Royal Charter in July 1662. [54] On 5 November 1661, Robert Moray proposed the appointment of a curator to furnish the society with experiments, and this was unanimously passed and Hooke was named on Boyle's recommendation. [9]
