How to Assemble Your Telescope
The giftboxes contain the optical tube assembly and the tripod with the equatorial
mount. The accessories are located within compartments custom-cut into the styro-
foam block inserts.
1.
Remove the components from the giftboxes: Remove and identify the tele-
scope’s equipment. Refer to Figures 1a through 1f for images of the parts and
the overall assembly of your telescope. When removing the tripod from the gift-
box, hold the assembly parallel (horizontal) to the ground or the inner tripod leg
extensions will slide out as they are not locked in place.
2.
Adjust the tripod legs. Spread the tripod legs as far as they will open. See Fig. 3.
3. Attach mount to tripod base: Place the mount over the tripod mounting base
(
37, Fig. 1c) with the protrusion on top of the tripod's base positioned between
the fine azimuth control knobs (27, Fig. 1d). See Fig. 4. If necessary, back off the
azimuth control knobs wide enough for protrusion to fit between them.
4. Attach the spreader bar to the tripod with shaft (see Fig. 5): Place the spread-
er bar (
36, Fig. 1c) over the T-handle shaft and thread the shaft through the tri-
pod mounting base (37, Fig. 1c) and into the hole in the telescope mount. Tighten
the T-handle to a firm feel. This attachment keeps the tripod and the telescope
mount securely in place. Then line up the spreader bar braces so that they are
each touching one of the tripods legs. Tighten the tension knob (
39, Fig. 1c) to a
firm feel. When you wish to collapse the tripod, loosen the tension knob and
move the braces off the legs. You do not need to remove the T-handle/shaft.
5. Attach the counterweight(s) to the counterweight shaft: Place the counter-
weight shaft base (
20, Fig. 1d) over the threaded end of the shaft (22, Fig. 1d).
Thread the shaft and base assembly into the hole beneath the Dec. setting circle
as depicted in Fig. 6.
Look through the hole in the counterweight and note the pin blocking the hole. Tilt
the counterweight slightly and the pin moves out of position, clearing the hole. If
the pin does not move, unscrew the counterweight lock knob slightly until the pin
moves.
Unscrew the safety cap (
23, Fig. 1d) from the shaft. Holding the counterweight
(21, Fig. 1d) firmly in one hand, slip the counterweight to approximately the mid-
point of the counterweight shaft (22, Fig. 1d). Tighten the counterweight lock
knob to a firm feel. Replace the safety cap.
