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.
For an equatorial GoTo telescope mount, the user must align the mount by hand with either the north celestial pole or the south celestial pole. Assuming the user is accurate in the alignment, the mount points the telescope to a bright star, asking the user to center it in the eyepiece.

Alt-alt mounts, or altitude-altitude mounts, are designs similar to horizontal equatorial yoke mounts or Cardan suspension gimbals. This mount is an alternative to the altazimuth mount that has the advantage of not having a blind spot near the zenith, and for objects near the celestial equator the field rotation is minimized. [7]
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.

Spectrography setup with autoguider (the autoguider camera body is attached to the finderscope, top right, and the guiding computer, bottom right). An autoguider is an automatic electronic guidance tool used in astronomy to keep a telescope pointed precisely at an object being observed.
In the Northern Hemisphere, rough alignment can be done by visually aligning the axis of the telescope mount with Polaris.In the Southern hemisphere or places where Polaris is not visible, a rough alignment can be performed by ensuring the mount is level, adjusting the latitude adjustment pointer to match the observer's latitude, and aligning the axis of the mount with true south or north by ...
Construction of the 150 ft (46 m) telescope started in the spring of 1964. The concrete base weighed 300 tons, the steel dish and its rotating mount another 900 tons. An equatorial mount in the base, only five feet high, positioned the instrument. The telescope was designed to operate at higher frequencies than existing instruments, requiring ...
