To set up the tripod, spread the legs outward until they are fully extended. Extend the center portion of each of the three tripod legs down 68". Use the three tightening screws located at the bottom of each leg to secure the extended legs in place. 4 5 6 All three legs should be the same length to provide a level platform for the telescope. Place the accessory tray on top of tripod's center leg brace. Thread the tray into the threaded hole in the center of the leg brace. Properly assembled, the accessory tray should appear as pictured above. 7 8 9 Locate the equatorial mount and place the base of the mount through the hole in the center of the tripod mounting platform. From underneath the tripod mounting platform, thread the mounting bolt with washer into the threaded hole on the bottom of the equatorial mount. Thread the attached latitude adjustment screw into the equatorial mount until the screw is touching the inside of the mount and the mount can no longer pivot up and down.
