Equatorial Mount

Astronomical Dictionary

A telescope mount so designed so that the two axes, which support it, are aligned, one to the polar axis and the other to the Earth's equator. Once an object is centred in the telescope's field of view, only the polar axis need be adjusted to keep the object in view. If the polar axis is driven at Sidereal rate, it will counteract the rotation of the Earth, keeping the object (except the Moon) stationary in the field of view.
