Peter,
Here's some diagrams which may be helpful in setting up ready for your polar alignment / Star alignment procedures
Cheers
Martin
PS: The closer you align and level your tripod to True South , and set your altitude as accurately as possible to local latitude , the closer your polar alignment will be prior to starting the Synscan polar alignment routine,in addition your first alignment star will end up closer to the centre of the reticle or eye piece. If your Tripod is too far off True South and not at the correct altitude then your first alignment star may not end up in the field of view of your eye piece.
If your using an eye piece for polar alignment and star alignment centering can I suggest to buy an Orion 20mm 70 deg illuminated reticle eye piece as they are excellent for star alignment and centering with a wide field of view, good eye relief and good optics
