altazimuth telescope in degrees, minutes, seconds (N or S)   height above sea level in metersthe person, company or institution that constructed the mounting  ambient     Earth based telescope  altazimuthin 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)
