later if you wish) and for maximum rigidity. NOTE—this may have been assembled at the
factory.
3. Now set the tripod with the equatorial mount attached in the standing position by spreading the
legs apart far enough for the tripod accessory tray (#32) to fit.
4. You are now ready to install the tripod accessory tray (#32). The tripod tray bracket (# 19) fits
into slots in the bottom of the tray (use the holes on the ends of the brackets). Use the bolts
(#32A) and wing nuts (#32B) to attach each bracket to the tray.
5. Tighten all bolts and wing nuts to ensure proper stability.
B. Before proceeding further, locate knobs #16, #22, #24 and #28 and tighten all of them finger tight after
orienting the mount as illustrated in figure 1.
1. Locate the declination cable holder (#13). Locate the declination cable (the shorter of the two
cables) and attach the cable (#18) to the cable holder by tightening the thumb screw on the cable
end. The thumb screw should be tightened down hard on the flat surface of the cable holder after
backing off the cable about 1/4" from being fully engaged. This method helps ensure there is no
slippage when using the cable.
2. You may reverse the position orientation of the Declination cable to suit your preference if
desired.
3. Locate the right ascension cable holder (#27). Locate the right ascension cable (#31) and attach it
the same way as the declination cable was attached in the last section.
4. Slide the counterweight shaft (#29) through the counterweight (#30). Use the counterweight lock
(#36) to lock the counterweight in place. By holding the counterweight in one hand, thread the
counterweight shaft clockwise into the equatorial mount (#33) as shown in figure 1.
C. Now you are going to put the telescope optical tube (#11) onto the equatorial mount (#33).
1. Remove the two bolts (with the supplied wrench) and washers (#40) from the telescope tube
mount bracket (#21). Put the bolts through saddle bracket (#41), as shown in Figure 1, into the
telescope tube mount bracket and tighten.
2. Loosen the tube mount bracket (#21) with the knob (#12) and open the bracket. Hold the tube in
the orientation as noted in figure 1. Holding the optical tube in place with one hand, close the tube
mount bracket and tighten the bracket knob to firmly hold the optical tube. NOTE: The optical
tube may come already mounted in the bracket
D. To attach the finderscope:
1. Remove the nuts (#37) from the studs where the finderscope will mount.
2. Mount the finderscope bracket (#5) by mounting the bracket over the studs protruding from the
tube and tightening it down with the supplied nuts (#37). Additional nuts may be included with
the bracket and these should be discarded.
