Alt-Azimuth mount is deemed to be the best for beginner amateur astronomers. It is light, not as bulky as the equatorial one, and is simple to use. It includes two perpendicular rotation axes (by height and azimuth), and both must be set up to follow an object. Alt-Azimuth mount is used to observe terrestrial objects or with telescopes for beginners. Even though the recent trend is to equip large-aperture professional telescopes with such mounts. Not least because of their reliability and steadiness.
