APPLICATION
Polar Alignment Scope
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 sold separately. The polar alignment scope can align the polar axis
of the mount as accurately as 3 arc minutes or less.
