The PF-L Assist app helps you to align the equatorial mount of your telescope to the north celestial pole or south celestial pole in order to make it turn parallel to earth’s rotational axes.
The app is helpful to match orientation of the constellation pattern drawn on the reticle of the polar alignment scope’s field of view with the constellation viewing in the real sky when you set up the equatorial mount with the polar alignment scope.
With use of the PF-L Assist, you can easily find direction of the constellation designated for polar alignment when the said constellation is hidden by trees or building, or when the night sky is affected by city lights, or when you set up your telescope at dusk.
The position of guide stars on the scales changes year by year due to precession of the Earth. The PF-L assist provides you the present location information of the guide stars to set up on the scales correctly. You will achieve the polar alignment instantly without performing a routine for setting of date and location. The app displays the current night sky which can be seen in your location.
