Stellarvue Surveyor's tripod. Tripod has a 59 mm recess at top and a 5/8”-11 mounting bolt. Safety chains are included. Attaches directly to the MEC2 column and M2C Mount head. 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 M2C mount and column adds 16” to total height). Tripod weighs only 10 pounds but is extremely stable thanks to its over-sized top. It is much more stable than the Asian import aluminum tripods. Total weight of TA with M2C mount and column is about 22 pounds. The M2, column and tripod will hold telescopes as large as our SV115T.
