QUICK-START GUIDE

It is recommended that you attach the supplied tripod to the LX90 for observing. Perform the telescope and AutoStar setup indoors in the light so that you become familiar with the parts and operation before moving the telescope outside into the dark for observing.

1.Remove the field tripod from the shipping carton. Stand the tripod vertically with the tripod feet down and with the tripod still fully collapsed. Grasp two of the tripod legs and, with the full weight of the tripod on the third leg, gently pull the legs apart to a fully open position.

2

2.Thread in two lock-knobs on each leg (six total) near the foot of each tripod leg. Use the lock- knobs to vary the height of the inner, extendible tripod leg sections. Tighten the locks to a firm feel only; do not overtighten.

3	Threaded
3	Rod	“C” Clip

3.Remove the threaded rod (see above figure) from the tripod head. A small piece of plastic holds the threaded rod in place. Remove the small plastic bag that is stapled to the threaded rod. This bag contains the "C" clip retainer and an extra clip.

4.Remove the spreader bar (see above figure) from the shipping carton. Slide the spreader bar onto the threaded rod and position the rod back through the tripod head. Place the "C" clip into the slot in the threaded rod – this clip holds the threaded rod in place. Position the spreader bar so that its three arms line up with the three tripod legs.

5

5.Take the LX90 from its packaging and place the entire telescope onto the top of the tripod head, inserting the threaded rod into the central hole in the bottom of the drive base of the telescope. Tighten the tension knob (see above figure) to a firm feel only; firm tightening of the tension knob is sufficient to result in rigid positioning of the tripod legs.
