astronoomiainstrumentide statiivile paigutamise viis, mille korral statiivi üks pööramistelg on vertikaalne ja teine horisontaalne
a telescope mounting that has axes in the horizontal and vertical planes to enable the telescope to be swivelled in altitude (perpendicular to the horizon) and azimuth (parallel to the horizon)

Traditionally, telescopes were constructed to have a mount with one axis aligned to the earth’s axis of rotation, known as an equatorial mount. Telescopes, such as the two Kecks, constructed to give motions in azimuth and altitude have many advantages over an equatorial one. However, an altitude-azimuth mount suffers from the following drawbacks: Variable drive rates in two axes A ‘blind spot’ when tracking close to zenith Field rotation at the telescope foci Pupil rotation at images of the aperture stop.
