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.

Mirrors and lenses are the critical light-bending components of a telescope. Objective: The first lens or curved mirror that collects and focuses the incoming light. ...
Principle of operation of an equatorial mount to keep a telescope pointing in the same direction, by CMG Lee. The black spots denote rotation axes seen end-on. The green telescope is rotated at the same rate as the earth but in the opposite direction, while the red telescope is not driven.
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]
The axis of an equatorial mount is parallel to Earth's surface when observing stars at Earth's equator – but perpendicular to it when observing from one of Earth's poles. Equatorial mounts were specifically developed for a spherical and rotating Earth. If Earth were flat, an equatorial mount would not make sense.
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 ...
OpenSCAD is a free and open source software that uses scripting to design 3D objects. [16] Many 3D printers can be upgraded with 3D-printed parts. Thingiverse users produce many improvements and modifications for a variety of platforms. Popular examples of community-based 3D printer projects include the RepRap project and the Contraptor project ...
