There are 3 hex grub screws near the viewing end of the polar scope to adjust this. When I got my mount new this was some way out.
Procedure:
Remove weights and get the polar scope aiming at a distant object such as the top of a power pole.
Rotate on the RA axis and watch that the reticule cross hair centre doesn't shift as you do so.
Adjust hex grub screws to centre the cross hairs to the axis of rotation. Loosen one, and firm up the other two to shift it in the desired direction. Its quite a fiddly operation but you should only have to do this once.

Thanks Geoff - yes I did spend quite a while with the scope pointing out a window at a distant light on a building. Not perfect, but no more than 1-2 times width of crosshairs movement when scope rotated.
Was aiming just over the neighbours' house over the road the whole time to target the distant light - probably would have looked a bit suss if they'd noticed my late night efforts!.....
