    Precession Dials

    Precession Dial shows a ring in the northern and southern sky marked in 1000 year increments depicting the rotational axis "wobble" of the Earth over its 26,000 year cycle. 



    To display the precession dials, open the Options pane, expand the Guides layer and then the Celestial Guides (Poles) sub-layer. Under Celestial Guides (Poles) check the “Pole Precession Circles” box.
