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.
Clock drive mechanism in the pier of the German equatorial mount for the 8-inch refracting telescope at Aldershot Observatory.. In astronomy, a clock drive (also known as a sidereal drive or field rotator) is a motor-controlled mechanism used to move an equatorial mounted telescope along one axis to keep the aim in exact sync with the apparent motion of the fixed stars on the celestial sphere.
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.
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 ...
Software and optical encoders corrected for errors, and the telescope also came with auto-guiding CCD and planetarium software. [2] A related series introduced in 2005 was the even higher end RCX400 (later renamed LX400-ACF), with new optics and a motorized focus/collimation system, and with upgraded fork mount electronics.
