2. Assembly
1. Attach the three aluminum tripod legs (A) to the yoke
mount (B)
(Figure 3a) with the three hinged leg braces fac-
ing inward. Three hex-head bolts (C) each about 3" long,
with 5/8" washers (C) and wing nuts (shown in
Figure 1
attached to the bolts), are provided for this purpose. Note
that the bolts should be inserted from the side of the leg
that has the hex-shaped hole, so that the bolt head seats
in the hex-shaped hole
(Figure 3b). The washer then the
wing nut are placed on the opposite side on the exposed
end of the bolt.
2. Attach a leg lock thumbscrew (D) to each leg as shown
(Figure 4). Extend the sliding inner portion of the adjust-
able-height tripod leg to the desired length for all three
legs. Lock in place by tightening the leg lock thumbscrews.
Do not over-tighten the leg lock thumbscrews or you
may damage the collar they are attached to.
3. Now stand the tripod upright, spreading the legs evenly
apart so the accessory tray can be positioned to attach to
the three leg braces.
4. Attach the accessory tray (E) to the leg brace supports
(Figure 5) with the three short screws (F), small (3/8”)
washers, and small wing nuts provided (washers and
wing hunts shown attached to the screws in
figure 1).
Place a washer on the screw. Then place the accessory
tray on top of one of the leg braces so that the mounting
screw passes through the hole at one of the corners of
the accessory tray, and through the slot in the leg brace.
Then place another small washer on the screw and thread
on and tighten the wing nut. You may find it helpful to use
the supplied screwdriver tool (O) to hold the screw heads
while tightening the wingnuts. Repeat this procedure until
the tray is attached to all three leg braces.
The tripod and yoke mount are now fully assembled (
Figure
6). Next you will install the telescope tube on the altazimuth
yoke mount.
5. With the optical tube (G) oriented relative to the yoke
mount (B) as shown in
Figure 7, line up the holes in the
attachment plates on the side of the optical tube with the
holes in the ends of the yoke mount (
7a). Then secure
the optical tube to the mount by inserting a yoke knob (H)
through the hole on each side of the yoke and thread them
into the attachment plates on the optical tube (
7b). They
should be reasonably tight but still allow movement of the
telescope up and down with gentle force.
6. Insert the altitude micro-motion rod (I) through the hole in
the metal receptacle on the yoke mount (
Figure 8a). You
may have to unthread the altitude lock knob a few turns to
provide clearance for the rod). Then attach the other end
of the rod to the metal anchor cylinder using the anchor
screw (J) provided (
Figure 8b). Use the supplied screw-
driver tool (O) to tighten the screw.
Finally, you will install a few accessories, then you’ll be ready
to observe!
7. To attach the red dot finder scope (K) to the optical tube,
orient the finder scope as shown in
Figure 9 and slide the
bracket foot into the finder scope base until it clicks. (To
remove the finder scope, press the small tab at the back of
the base and slide the bracket out.)
8. Insert the star diagonal (L) into the focuser drawtube and
tighten the thumbscrew on the drawtube collar (
Figure
10). Then insert the 25mm eyepiece (M) into the diagonal
