altazimuth telescope in degrees, minutes, seconds (N or S) height above sea level in meters the person, company or institution that constructed the mounting ambient Earth based telescope altazimuth in degrees, minutes, seconds (E or W) A form of mounting similar to that of a radar which allows the telescope tube to be moved horizontally (by rotation in azimuth or compass direction) and vertically (by rotation in altitude or elevation). To follow a star the telescope must be adjusted simultaneously in both axes. (also called alt-az)

optical telescope astroweb electromagnetic telescope

Ritchey-Chrétien the person, company or institution that created the mirror concave hyperboloid equal to aperture (except for Schmidt which has aperture smaller than mirror diameter) material and other engineering details or primary mirror diameter Ritchey-Chrétien reflector convex hyperboloid A system of two mirrors, aspherized to give an image at the secondary (Cassegrain) focus free from spherical aberration and coma.

segmented mirror telescope the person, company or institution that created the mirror equal to aperture (except for Schmidt which has aperture smaller than mirror diameter) material and other engineering details or primary mirror diameter reflector a reflecting telescope whose mirror is composed of multiple segments
