Polar scope for SkyWatcher EQ3 & Celestron CG4 mounts

This polar scope is a very useful accessory, suitable for the SkyWatcher EQ3 and the Celestron CG4 mounts. It makes polar alignment easier, faster and more accurate, so that the observer needs less time for preparation and has more time for observation.

There is an external scaled disk with 2^ο divisions. Inside the scope there is an interposition of guiding marks: Big Dipper, Cassiopeia, Polar Star and North Celestial Pole for the observer of the northern hemisphere; constellation Octans for the observer of the southern hemisphere.
