Support@Seestar But how can I optimize the polar alignment other than bringing the two values near 0.0? It normally took me less than a minute to bring both values near to 0.0, mostly 0.2 or so. When I compare even direct consecutive exposures, the stars always jump back and forth clearly. The equatorial orientation of the frames, on the other hand, remains pretty much the same, there is only very minimal or no field rotation over all exposures, sometimes hundreds over hours.
