10 Push the washer up on the bolt as far as you can with y our fingers (Figure 8a). Then place the inser tion tube on the bolt (Figure 8b) and use it to push the washer farther up on the bolt, into the counterbored hole in the wood (Fig - ure 8c). The washer will keep the bolt captive when it is fully disengaged from the mating par t of the base.
11 encoder disk so the registration feature on the bushing goes into the hole in the encoder disk. Carefully position the top baseplate (D) ov er the ground 11. baseplate (A) and lower it so the brass azimuth bushing (F) goes through the center hole in the top baseplate (Figure 11) .
12 to do , but b y lightly pressing the scre w tips into the holes, they should “stick” enough so that you can screw them in without one or more of them (and the w ashers) f alling out. Using a small Phillips screwdriver , tighten all four screws (Figure 14).

14 T o install the mirror cell into the optical tube, the rear end 1. ring attached to the lower section of the optical tube must first be remov ed. This is done b y unthreading and remov- ing the eight Phillips-head screws that connect the end ring to the tube (Figure 18), and then pulling the end r ing off of the tube.
15 Assembling the end r ing (and mirror cell) back onto 5 . the tube can be a bit tr icky . This is because the large diameter and thin metal of the tube will cause the tube to become somewhat out of round once the end ring is remov ed.
16 Note: If desired, you can mount the low er tube section on the base bef ore connecting the tr uss pole assemblies and upper tube section (Figure 24). Y ou ma y find it easier to lift the lo wer 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 .
17 Firmly tighten the eight clamping knobs on the lo wer truss 9. suppor t ring. If , after assembling, the truss poles are loose within the 10. truss connectors, use the supplied 4mm he x ke y to tight- en the button head cap screws which connect the poles to the truss connectors (see Figure 26 ).

Push the finder scope through the brac ket until the O-ring seats just inside the front opening of the brac ket.
20 Collimating is the process of adjusting the mirrors so they are aligned with one another .
21 and causing damage if something comes loose while y ou are making adjustments. Place a sheet of white paper inside the optical tube directly opposite the f ocuser . The paper will provide a bright “background” when viewing into the focuser . When properly set up for collimation, your telescope should resemble Figure 37.

24 motion; this ensures optimal perf or mance. The motion should be ideal – not too stiff, not too loose. Y ou will want to be able to “track” the motion of celestial objects while viewing them .
25 Now look through the finder scope. Ideally , the object should be within the field of view . If not, then coarse adjustments to the brack et’ s alignment thumb screws will be needed.

27 Loosen the eight captiv e connecting bolts that attach the 2. side and front panels to the top baseplate (Figure 45). Y ou will hav e to tur n the hand knobs about sev en full turns or so to unthread the bolts completely from their receptacles in the top baseplate.

29 get better later in the ev ening, as much of the heat absorbed by the Ear th dur ing the da y has radiated off into space. In conditions of bad seeing, stars will twinkle and objects will appear unsteady and blurry in the telescope.
30 objects like planets and double stars. The Moon also takes higher magnifications well. Deep sky objects, howe ver , typically look better at medium or low magnifications. This is because many of them are quite f aint, yet hav e some e xtent (apparent width).
