Several names are given to this kind of mount, including altitude-azimuth, azimuth-elevation and various abbreviations thereof. A refracting telescope (with finderscope and accessories) on a small alt-azimuth mount. Rotation about the horizontal axis varies the altitude (angle of elevation) of the pointing direction. On the other hand, an equatorial mount only needs to be rotated about a single axis, at a constant rate, to follow the rotation of the night sky (diurnal motion). Filters Sort by .
