Note: If desired, you can mount the lower tube section on the
base before connecting the truss pole assemblies and upper
tube section

(Figure 24). You may find it easier to lift the lower

tube section and guide it onto its resting place on the base’s
bearing cylinders than hoisting and mounting the fully assem-
bled optical tube.

7. Connect the upper tube section to the four truss connec-

tors at the top of the poles. Orient the upper tube section
as shown in

Figure 25. Hold the upper tube section with

one hand while threading the knobs in the truss connec-
tors into the holes in the upper truss support ring. If nec-
essary, you can slightly adjust the position of the truss
connector with respect to the pole ends in order to have
the knobs and holes line up

(Figure 26). When tightened,

the knob will clamp the truss connector against the regis-
tration flats on the upper truss support ring

(Figure 27).

Repeat this for the other three truss connectors. Firmly
tighten the knobs.

8. Firmly tighten the eight clamping knobs on the lower

truss support ring.

9. If, after assembling, the truss poles are loose within the

truss connectors, use the supplied 4mm hex key to tight-
en the button head cap screws which connect the poles

Figure 24.

Rather than assembling the entire optical tube and

then hoisting it onto the base, some may find it more convenient to

mount the lower tube section on the base first, then install the truss

tubes and upper tube section.

Figure 25.

When the optical tube is assembled, the upper tube

section should be oriented relative to the lower tube section as

shown. Note the orientation of the focuser on the upper tube section

relative to the side bearing on the lower tube section.

Figure 26.

The position of the truss connectors relative to the

pole ends can be adjusted to register the truss connectors with the

upper truss support ring.
