Components guide
If your intention is to take long exposure astrophotography, you must accurately align the polar axis (R.A) of the mount to the
celestial pole. This requires the use of a polar alignment scope. The polar alignment scope can align the polar axis of the mount as
accurately as 3 arc minutes or less.
There is a push switch on the top of the brightness adjusting dial of the polar
alignment scope. Pushing the switch will illuminate the polar alignment reticle
in red light. The red light becomes dimmer gradually after a certain interval of
illumination (about one or two minutes) and turns off automatically.
The brightness of the red light for the polar alignment reticle can be varied in 8 steps by turning the
brightness adjusting dial of the polar alignment scope.
You can focus on the polar alignment reticle by turning the eyepiece of the polar alignment
scope. While holding the body of the polar alignment scope on one hand, turn the eyepiece
part with the other hand.
