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