Meaning and Definition
A two-axis support system for an instrument, allowing movement up-down (altitude) and left-right (azimuth).
A simple, common type of mount for telescopes, cameras, or antennas that pivots on a vertical (azimuth) and a horizontal (altitude) axis. It is intuitive to use but does not compensate for the Earth's rotation, unlike equatorial mounts. Used in amateur astronomy, surveying, and satellite tracking.

FAQ
Frequently Asked Questions
It's a blend of 'altitude' (angular height above the horizon) and 'azimuth' (angular direction along the horizon).
Yes, its up-down, left-right movement is very intuitive and easy to understand, making it excellent for beginners.
It is challenging for long exposures without a field rotator, as the image will rotate. Short-exposure planetary imaging is possible, and modern 'goto' altazimuth mounts can track objects with computer control.
It is a specific, popular type of simple, low-cost altazimuth mounting made for Newtonian telescopes, using friction bearings for smooth movement.
A two-axis support system for an instrument, allowing movement up-down (altitude) and left-right (azimuth).
Altazimuth mounting is usually technical / scientific in register.
