Adjust Polar Scope Focuser
If the polar scope does not focus on the distant object, take the polar scope out of the mount
housing. Point the polar scope to a far distant object. Adjust the Objective Lens by turning the tube
to get a clear image. Tune the lock ring to secure it.
Replace the Polar Scope back to the mount and tighten it. Adjust the Eyepiece to get a clear
picture of the reticle.
Polar Scope Alignment:
If you are suspecting that the polar scope may be misaligned to the mount R.A. axis, you may
check it by putting a star in the center of the polar scope reticle cross hairs and rotating mount’s
R.A. axis. If the star stays in the center of cross hairs, the polar scope is aligned to the mount’s R.A.
axis.
In the event the polar scope optical axis needs to be adjusted, you can do this procedure at night
while pointing at Polaris. However, it is probably easier to do it during the daytime using a distant
point, such as a flag pole or top of a building a couple of hundreds away, as your target. Please
remove the telescope, the counterweights and counterweight shaft from the mount. Aim the mount
to the object. Use the Latitude Adjustment Screw and Azimuth Adjustment Knob to center the
object.
