Telescope mountings
The simpliest telescope mounting is an altazimuth mount. It is similar to that of a surveying transit. A fork rotates in azimuth, and bearings on the tips of the fork allow the telescope to vary in altitude.
Telescope mountings
The classical mounting for an astronomical telescope is to have an axis parallel to the Earth's north-south axis, called an equatorial mounting.
Telescope mounting, equatorial:
One rotatable axis, set parallel to the earth's axis of rotation, compensates for diurnal motion of the heavenly bodies in right ascension. The other axis permits adjustment in declination.
A type of telescope mounting that supports the weight of the telescope and allows it to move in two directions to locate a specific target. One axis of support is vertical (called the altitude) and allows the telescope to move up and down.
The various telescope mounting systems available for use by amateur astronomers have been discussed at length on sci.astro.amateur.
