TELESCOPE ASSEMBLY INSTRUCTIONS
1. Remove the three tripod legs (U) from the box. To attach tripod legs to tripod head (N) align the
holes of the tripod legs with those of the equatorial mount. Secure each leg by inserting a large (3")
bolt with washer into the hole and secure with a wing nut and washer. Tighten bolts (Fig. 1).
NOTE: When attaching tripod legs to tripod head, be sure that hinge flange on each leg
faces inward. The tripod accessory tray (W) will attach to these flanges.
2. Stand tripod and spread legs. Loosen the adjusting lock on each leg. Grab the equatorial mount
and lift. Extend the tripod legs to the desired height (at equal lengths). In addition,
tighten each legʼs adjusting locks to hold them in position (Fig. 2).
3. Using the small machine screws and wing nuts provided, attach the accessory tray to each of
the flanges on the tripod legs (Fig. 4).
NOTE: Flanges fit under accessory tray when attached.
4. Remove telescope main body (J), counterweight (R), counterweight rod (S), and the two
flexible control cables (A) from the box. Carefully rest the telescope main body tube in the
cradle (Fig. 11) Be sure the cradle is positioned at the center of the telescope main body tube
for proper balancing. Tighten the cradle locking knobs (Fig. 11a). Attach the control cables to
the declination (P) and hour axis (Q) cable studs. Loosen counterweight clamping screw (Fig.
12b). Slide weight into rod. Thread counterweight rod into the threaded hole located below the
declination axis (Fig. 12c).
5. Models 1000/90, 800/203, 1400/150, 900/60, 900/70: Remove telescope main body (J),
counterweight (R), counterweight rod (S), and the two flexible control cables (A) from the box.
Remove the knurled nuts from the telescope mounting studs. Seat telescope main body in "V"
block and secure with the nuts. Attach the control cables to the declination (P) and hour axis
(Q) cable studs. Loosen counterweight clamping screw. Slide weight into rod. Thread
counterweight rod into threaded hole located below the declination axis.
6. Models 1000/90, 700/76: Remove the finderscope with finderscope bracket (H) attached from the
box. Remove the two knurled thumbscrews from the telescope main body. Position the
finderscope bracket on the telescope main body so that the holes in the base of the bracket line
up with the exposed holes in the telescope main body. Replace the two knurled thumbscrews
and tighten securely (Fig. 4b).
7. Models 1000/90, 800/203, 1400/150, 900/76, 300/76, 1000/114: Remove the StarPointer
finderscope with finder- scope bracket (H) attached from the box. Remove the two knurled
thumbscrews from the telescope main body. Position the finderscope bracket on the telescope
main body so that the holes in the base of the bracket line up with the exposed holes in the
telescope main body. Replace the two knurled thumbscrews and tighten securely (Fig. 4a).
8. Insert diagonal (E) into the focus tube (Fig. 5a). Secure by tightening small retaining screw.
NOTE: Diagonal is only to be used in combination with the eyepieces (oculars). Never use
the diagonal and Barlow at the same time.
9. Insert eyepiece (G) into diagonal (Fig. 5b). Secure by tightening small retaining screw.
10.Insert Barlow (Fig. 7) into the focus tube. Secure by tightening small retaining screw. Insert
eyepiece into open end of Barlow and secure (Fig. 6).
NOTE: In all astronomical telescopes, the image appears upside down. With the use of the
diagonal in refractor models, the image appears erect but with a left to right inversion (mir-
ror like). To use the telescope for terrestrial view and to correct the mirrored image, remove
the diagonal and replace with the erecting eyepiece. We recommend the use of the low
magnification eyepiece when the telescope is used for terrestrial viewing.
Refractor telescopes can be used for terrestrial viewing by using an erecting eyepiece.
Reflectors are used mainly for astronomical purposes.
The telescope is now fully assembled and ready for use.
CAUTION! Viewing the sun can cause permanent eye damage. Do not view the sun with
this telescope or even with the naked eye.
