PRIMARY MIRROR INSTALLATION
1. When installing the mirror into the optical tube, you
must rst remove the rear end ring attached to the lower
section of the optical tube. Simply unthread and remove
the eight Phillips-head screws that connect the end ring
to the tube (Figure 1), and then pull the end ring off of
the tube.
Caution: The raw edge of the tube itself will be exposed
after the rear end ring is removed from the tube. Be
careful not to cut or injure yourself on the tube’s edge.
Please also be careful not to pinch your ngers when
attaching the assembled mirror cell onto the tube.
Fig.1
Figure 1. To remove the rear end ring, unthread the eight screws on the tube.
2. Before beginning to assemble the rear end ring to the mirror support cell, nd a clean, at surface
and place a clean cloth or towel on it. Turn the mirror cell over so that the mirror is facing downward
and then put it down on the cloth. Place the three springs onto the three exposed threaded shafts
(see Figure 2a). Lower the end ring onto the mirror cell so that the threaded shafts pass through it,
and the end ring rests on the springs (Figure 2b). Add a nylon washer to each collimation knob and
thread the collimation knobs through the end ring and onto the threaded shafts (Figure 2c). Conrm
that the knobs have at least three full turns of engagement on the shafts. The mirror and end ring
assembly is now all set to be installed onto the lower tube section.
Fig.2a Fig.2b Fig.2c
Figure 2. (a) Place the three springs on the exposed threaded shafts of the mirror cell (b) Lower
the rear end ring onto the mirror cell so that the threaded shafts of the mirror cell pass through
the end ring, and the end ring rests on the springs (c) Thread the collimation knobs, with nylon
washers attached, through the rear end ring and onto the threaded shafts. Check that the knobs
have at least three full turns of engagement on the shafts.

Fig.3
Figure 3. Find the area of tube that is bulging out and obstructing it from seating in
the end ring. Press on the bulge to force
the tube into the end ring.
3. It can be a tricky task when assembling the end ring (and mirror cell) back onto the tube.
The complication is that the large diameter and thin metal of the tube will cause the tube to
become somewhat out of round once the end ring is removed. To assemble the rear end ring
(with mirror and mirror cell now connected) to the tube, position the lower section of the tube
up vertically so that the raw edge of the tube is up. Line up the threaded holes in the edge of
the end ring with the holes in the end of the tube. Then, lower the entire assembly onto the
tube. (Be careful to avoid nger pinching during this step.) There may be a bulge in the
perimeter of the tube that obstructs the end ring from fully seating onto the tube (Figure 3).
Simply press the bulge down and the entire mirror cell assembly should seat onto the tube.
Now, replace the eight Phillips screws that connect the rear end ring to the tube.

TELESCOPE SETUP
Place the mount on the ground. Place a bubble level on
1.
the top of the round base to ensure the mount is set on a
leveled plane. Better leveling will yield better tracking
performance.
To extend the telescope tube, loosen the three slider lock
2.
screws and pull the top part of the telescope assembly
out until it clicks in place Tighten the slider lock screws.
Do not over-tighten.
Remove the dust cap and the protective cover in the front
3.
of the tube.
Loosen these screws
Grab the telescope tube with both hands at the positions indicated in the diagram below.
4.
Hold the telescope tube directly above the mount. Align the side bearings of the tube to the
5.
mounting platforms on the inner side of the side boards. Lower the telescope tube and
carefully place it on the base.
Tighten the locking screw to secure the tube in place.
6.
Mounting platform. Make sure that
the side bearing aligns with this
when placing the tube on the mount.
Lift up the telescope tube by holding here
Optical Tube
Locking screw
Locate the finderscope bracket
7.
and carefully remove the
rubber-o-ring from it. Position
the o-ring into groove on the
finderscope tube.
Slide the finderscope bracket
8.
into the mounting slot and
tighten the screw to hold the
bracket in place.
Loosen the two adjusting screws
9.
on the bracket. Pull back the
spring-loaded screw and position
the finderscope into its bracket by
sliding it backwards until the rubber
o-ring seats.
