if you move the ra to the left and your polar scope is out which it obviously is dont ctr it you only correct half the amout then rotate mount to the right see were it is then use the azumith screws to correct the other half of correction then try again. does that make sence

1. Find a suitable target in your polarscope. Center it on the cross hairs.

2. Unlock the RA axis and rotate the mount 180 degrees. Remove half of the error using the adjustment screws on the polarscope.

3. Rotate the mount back 180 degrees and adjust again, repeat 2 and 3 untill there is no error.

Try swopping out the hex screws for thumb screws, it makes it much, much easier.

On the skywatcher polarscopes they are usually the same size as the barlow thumb screws.
