The Celestron Heavy-Duty Alt-Azimuth Tripod is perfect for hands-free viewing with giant binoculars or a spotting scope.The fully adjustable aluminum legs provide a minimum height of 32 inches and a maximum height of 45 inches. A center brace stabilizes the legs when the tripod is open, and a metal accessory tray in the center of the brace keeps your accessories close at hand. The alt-azimuth tripod head is made of metal and offers two control methods. For large altitude adjustments, simply move the mount to the desired position, and the friction clutch will hold it in place. For azimuth adjustments, loosen the azimuth lock to spin the mount up to 360º. Use the slow-motion control handles to make small adjustments for slow-moving targets like celestial objects drifting across the night sky or boats moving through water. Equipment is mounted on the tripod head using a standard 1/4”-20 thread mounting bolt, which slides along a slot in the mounting plate. This allows you to adjust the forward and aft position of your telescope, spotting scope, binocular mount adapter, or camera to maintain balance. This feature is especially useful for refractor telescopes and cameras with long lenses, which can become unstable if positioned too far forward.
