2. Altazimuth mount - Wikipedia

   en.wikipedia.org/wiki/Altazimuth_mount

   An altazimuth mount or alt-azimuth mount is a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes – one vertical and the other horizontal. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument.

3. Telescope mount - Wikipedia

   en.wikipedia.org/wiki/Telescope_mount

   William Herschel's 49-inch (1,200 mm) 40-foot telescope on an altazimuth mount. Altazimuth, altitude-azimuth, or alt-az mounts allow telescopes to be moved in altitude (up and down), or azimuth (side to side), as separate motions. This mechanically simple mount was used in early telescope designs and until the second half of the 20th century ...

4. GoTo (telescopes) - Wikipedia

   en.wikipedia.org/wiki/GoTo_(telescopes)

   Alt-azimuth GoTo mounts need to be aligned on a known "alignment star", which the user will centre in the eyepiece. From the inputted time and location and the star's altitude and azimuth the telescope mount will know its orientation to the entire sky and can then find any object.

5. Horizontal coordinate system - Wikipedia

   en.wikipedia.org/wiki/Horizontal_coordinate_system

   Therefore, the horizontal coordinate system is sometimes called the az/el system, [1] the alt/az system, or the alt-azimuth system, among others. In an altazimuth mount of a telescope , the instrument's two axes follow altitude and azimuth.

6. Equatorial mount - Wikipedia

   en.wikipedia.org/wiki/Equatorial_mount

   A large German equatorial mount on the Forststernwarte Jena 50cm Cassegrain reflector telescope. An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, called polar axis, parallel to the Earth's axis of rotation. [1] [2] This type of mount is used for astronomical telescopes and cameras.

7. Equatorial platform - Wikipedia

   en.wikipedia.org/wiki/Equatorial_platform

   A large portable Newtonian telescope on an altazimuth mount with a third equatorial axis platform mount consisting of a pivot and radius bearing surfaces.. An equatorial platform or equatorial table is an equatorial telescope mount in the form of a specially designed platform that allows any device sitting on it to track astronomical objects in the sky on an equatorial axis. [1]

8. Astronomical coordinate systems - Wikipedia

   en.wikipedia.org/wiki/Astronomical_coordinate...

   The equatorial describes the sky as seen from the Solar System, and modern star maps almost exclusively use equatorial coordinates. The equatorial system is the normal coordinate system for most professional and many amateur astronomers having an equatorial mount that follows the movement of the sky during the night. Celestial objects are found ...

9. Dobsonian telescope - Wikipedia

   en.wikipedia.org/wiki/Dobsonian_telescope

   Equatorial platform: The use of equatorial platforms (such as the Poncet Platform) fitted under the altazimuth mount has given users limited equatorial tracking for visual and astrophotographic work. Such platforms can incorporate a clock drive for ease of tracking, and with careful polar alignment sub-arc second precision CCD imaging is ...
