It is a good idea to adjust the height of the tripod before
attaching the fork arm and optical tube. Minor adjustments
can be made later. To adjust the height of the tripod legs:
3. Loosen the tripod leg clamp knob located on the side of
each leg (Figure 1) .
4. Extend the inner portion of each leg to the desired
length.
5. Tighten the tripod leg clamp knobs to secure each leg in
place.
Also, be sure to tighten the large wingnuts at the top of each
leg, where it attaches to the tripod mounting platform.
Attaching the Mount Arm to the Tripod
1. Place the mount arm base inside the tripod mounting
platform. See Figure 4.
2. Thread the coupling screw into the hole at the bottom of
the mount arm base and tighten with the large coupling
knob.
Attaching the Telescope Tube to the Mount Arm
1. Unthread the tube lock bolt until the bolt tip is not
protruding into the saddle slot.
2. Slide the tube dovetail bar into the saddle on the mount
arm as shown in Figure 5, and secure it by tightening the
tube lock bolt.
WARNING: NEVER ATTEMPT TO MOVE THE TELE­
SCOPE BY HAND! Otherwise, the gears and motors may
be damaged. Move the telescope only electronically with
the hand controller.
Inserting the Star Diagonal (Mak­Cass and Refractor)
and/or Eyepiece
A star diagonal is used with the Maksutov-Cassegrain and
refractor models to divert the light at a right angle from the light
path of the telescope. This allows you to observe in positions
that are more comfortable than if you were to look straight
through. A diagonal is not used with Newtonian reflectors;
none is included with the StarSeeker reflector models.
To attach the star diagonal:
1. Remove the protective dust cap from the 1.25" accessory
adapter.
2. Loosen the two thumbscrews on the 1.25" adapter and
slide the chrome portion of the star diagonal into the
adapter (see Figure 6).
