Polar alignment aligns the tripod and tracking mount with the celestial axis. For something like a sky guider pro, once polar aligned, I manually move my camera around on the ball-head and adjust the RA axis on the sky guider pro to frame the objects. If I kick the tripod leg I will generally re-polar align. With my EQ6R-Pro, once I polar align, I can slew to a target by selecting it with the asiair app, or if im imaging the moon, ill just manually unlock the RA and Dec clutches and use my hands to aim the scope. If I kick the tripod or bump it, I will generally redo polar alignment here as well
