should be reasonably tight but still allow movement of the
telescope up and down with gentle force.
7. Insert the altitude micro-motion rod (I) through the hole in
the metal receptacle on the yoke mount (Figure 9a). 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 9b). Use the supplied screw-
driver tool (K) to tighten the screw
9. Finally, insert the 25mm eyepiece (N) into the focuser (take
the dust cap off the focuser rst) and secure it by lightly
tightening the thumbscrew on the focuser (Figure 11).
8. Install the red dot nder scope (L) on the optical tube. Do
this by orienting the nder scope as shown in Figure 10
and sliding the bracket foot into the nder scope base until
it clicks. (To remove the nder scope, press the small tab
at the back of the base and slide the bracket out.)
9. Now remove the small dust cap from the focuser draw-
tube, and rst insert the mirror diagonal (M) into the draw-
tube, making sure that the thumbscrew on the drawtube
collar is backed out enough to allow the diagonal’s barrel
to slide into the drawtube. Then tighten the thumbscrew.
10. Finally, insert the 25mm eyepiece (N) into the diagonal
and secure it by lightly tightening the thumbscrew on the
diagonal (Figure 11).
The telescope is now completely assembled! Before it can be
effectively used, however, there are a couple of things to do to
prepare the telescope for operation.
3. Preparing the Telescope
for Operation
Aligning and Using the Red Dot Finder Scope
The included red dot nder scope (L) (Figure 12) makes
pointing your telescope almost as easy as pointing your n-
ger! It’s a non-magnifying aiming device that superimposes
a tiny LED red dot on the sky, showing exactly where the
telescope is pointed. It permits easy object targeting prior to
observation in the higher-power main telescope.
Before you can use the red dot nder scope, you must remove
the small plastic tab sticking out from the battery compart-
ment (Figure 12). Doing so will allow the pre-installed 3V
CR-2032 button cell battery to make contact with the nder
scope’s electronic circuitry to power the nder’s red LED illu-
minator. The tab can then be discarded.
To use the red dot nder scope properly, it must be aligned
with the main telescope. This is easiest to do during daylight
hours, before observing at night. Follow this procedure:
1. First, remove the dust cover (P) from the front of the tele-
scope.
2. With the 25mm eyepiece already installed from step 10
above, point the telescope at a well-dened land target
(e.g., the top of a telephone pole) that’s at least a quar-
ter mile away. When pointing the telescope, be sure to
loosen the azimuth lock knob and micro-motion lock knob
(for coarse movement in altitude) to allow the telescope to
rotate freely about both axes.
3. Center the target in the eyepiece.
Note: The image in the eyepiece will appear mirror reversed.
This is normal for refractor telescopes used with a standard
star diagonal.
4. Turn on the red dot nder scope by sliding the power
switch to ON (refer to Figure 12). The “1” position provides
dim illumination while the “2” position provides brighter illu-

tripod leg.
