The non-sidereal motion widget is provided for objects whose motion is significantly different from sidereal motion, e.g., comets and asteroids. It should not be regarded as a means of correcting or refining normal POCO tracking (see instead Guider Correction).
Rates are an increase or decrease relative to the sidereal rate and are entered directly into the RA and Dec boxes, or can be incremented or decremented by large or small steps using the <<, <, >, and >>, buttons. Pushing set initiates the rate. Null zeros the rate and returns POCO to normal tracking.
POCO can also learn tracking rates from the guider via the "Learn Rates..." function.
