Abstract:
A polar scope for a telescope mount includes a reticle having a pattern with multiple markings that allows users to accurately position pole stars for precise polar alignment. A system and mount may be provided including a polar scope of this kind. The polar scope may be provided with a controller that calculates the apparent position of a pole star, while accounting for errors, such as proper motion, precession of the earth's axis, and/or atmospheric refraction.
