Stellarvue heavy duty Surveyor's tripod with Appleply Tray. Just open the tripod legs, part way, extend the tray slots a little and pop it into place. Tripod has a 59 mm recess at top and a 5/8”-11 mounting bolt. Attaches directly to the M2 Mount when attached to the MEC2 column. Tripod is 36” - 58.5” in height when in use. Legs are 40” in length when retracted. For the best stability keep the tripod under 48” in height. Remember to add the height of the mount and column (the M2 mount and column adds 18” to total height). Tripod with tray weighs only 11.6 pounds but is extremely stable thanks to its over-sized top. It is much more stable than import aluminum tripods. Total weight of TA with M2 mount and column is about 19.2 pounds.
