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) |
Cassegrain | | | | | | | | | the person, company or institution that created the mirror | | | concave paraboloid | equal to aperture (except for Schmidt which has aperture smaller than mirror diameter) | material and other engineering details | or primary mirror diameter | reflector | | | | | convex hyperboloid | Telescope devised by Cassegrain in which an auxiliary convex mirror reflects the magnified image, upside down, through a hole in the center of the main objective mirror - i.e., through the end of the telescope itself. It was, however, no improvement on the gregorian telescope invented probably slightly earlier. |
