STEP 2. Install the polar scope
Before installing the polar scope onto the mount, face the polar scope to a bright source, such
as the sky (but not the SUN) or a lamp from a distance. Adjust the eyepiece to focus the reticle
pattern. Then face the polar scope to a distant object and look through the eyepiece. If you cannot
see the distant object clearly, the polar scope is not focused for your eyesight. Release a few turns of
the Lock ring (or hold the objective lens and turn it counterclockwise). Turn the Objective lens until the
image is focused. Retighten the Lock ring.

Remove the front cover of the polar telescope. Loosen the Polar Scope Locking Screw until it
does not intrude into the polar scope mounting hole. Gently insert the polar scope all the way into the
polar scope mounting hole from the back of the mount and with the flat platoon on the polar scope
facing left, as shown in Figure 7. Finger tighten (not too tight) the Polar Scope Locking Screw. Turn
the mount power on. Press the Polar Scope Illumination Adjustment Button to adjust the brightness of
the dark field reticle.
Tip: The polar scope can be tightened by the Polar Scope Locking Screw from either the side or
bottom. The bottom position is better for storage.
STEP 3. Attach the SkyTracker
The SkyTracker
shown in Figure 8. When the alt-azi base is not used, a ball head (#3305A, not included) is suggested
for easy adjustment.
