Does anyone have experience using the 'quick drift' method of polar alignment as described in AP's documentation?
This method uses the finder scope and removes orthoganal-issues. (I'm using a Mach1GTO)

I get the altitude portion fine - within a few iterations the star is hidden behind the crosshairs on both sides of the meridian.

BUT when adjusting the az. - I can't get the star centered on the crosshairs! It's always off center either above or usually below the crosshair center. Maybe 2 out of 10 times it seems to work. The star will often center if the az. lockdown knobs are completely loose but that defeats the purpose.
This issue has ruined more imaging hours than I can count....

Can anyone help me out? Maybe someone can explain their process for using this method??
