Vixen’s latest design of polar finder, allows a simple, hassle-free method of polar alignment. The Vixen Polarscope PF-L II for AP & SX mounts has a reticule showing the Pole star (Polaris) and two other stars (Delta UMi and 51 Cep) in their precise positions. By turning the Polarscope you can easily match the reticle with the asterism of these stars in the sky and mechanically adjust your mount’s azimuth and altitude axes to align to the true North Pole. You can then adjust the Polar star to a more precise alignment using the reticule’s year marking (which runs from 2015 to 2040, but in practise can be used much longer after this) .

Using this alignment process, with visual reference to the actual stars in the sky, a complicated alignment, using date and time to calculate Polaris offset from the pole is unnecessary. For alignment in the Southern Hemisphere you simply use the Trapezium asterism (Sigma, Chi, Tau and Upsilon Octantis) of the constellation Octans and position the reticule with the trapezium stars aligned to their marked positions.
The Polarscope has built-in LED illumination, which is dimmable in many stages, and ensures an automatic shut-off after 2 minutes, saving your battery life.

The PFL-II also has an improved edge sharpness, when compared with its predecessor.
