iOptron combined the strength and stability of a pier, with the portability and leveling flexibility of a tripod to produce their Tri-Pier; offered here with white legs and a black center column. Designed to provide a rock-solid platform for their GoTo mounts, the pier and leg tops are made of lightweight and durable aluminum, with stainless steel leg extensions. Its feet have built-in vibration-suspension pads for increased stability and visual clarity. It has a payload capacity of 220 pounds to handle even the largest OTAs and accessories, with an adjustable height from 31.5 to 42.5" and an uneven ground range of 3.35" (8.5cm). It folds up into a relatively compact 26 x 12.8" package, and the legs store inside the pier.
