ASSEMBLE PIER OR TRIPOD

Begin by assembling the pier or tripod at the observing location.

ADJUSTABLE ALUMINUM TRIPOD: Extend the legs to the desired height; secure with the locking levers. Adjust the

distance between the legs. Place the legs far enough apart to provide a solid base of support.

ADJUSTABLE HARDWOOD TRIPOD: Remove the tripod from its carrying case and attach the shelf to each of the

three legs with the knobs provided. Adjust legs to the desired height and spread. Lock in position with the hand

knobs.

PIER: Slide the three legs onto the nubs of the base. Place the pier post on the base and attach the tension rods. The

turnbuckles should be drawn tight until the whole assembly is stiff enough to support your weight without

movement.

ASSEMBLE MOUNT TO PIER OR TRIPOD

In order to track the motion of astronomical objects, the polar axis must be positioned so that an imaginary line drawn

through the hollow shaft points toward the celestial pole. At this stage of the assembly process, you want to position

the mount so that it points roughly north. Place the mount into the top of the pier or tripod so that the threaded R.A.

axis hole is on the south side of the pier/tripod. Line up the holes of the mount and pier/tripod. Screw in the three

hand knobs to hold the mount in place.
