The way I have been doing it (and this seems to work for me, others may do it differently)
1 Setup the mount as accurately as I can.
2 Do a 2 star alignment. This is only to check how close the Synscan thinks my Polar Alignment is by checking the result at the end.
3 Go through the Synscan Polar Alignment routine. I only do this step if the error is over 30' on both RA and Dec otherwise I skip to step 5.
4 Do a 3 Star alignment. This is really only to get reasonable accurate pointing so I can be confident the scope is pointing where I want.
5 Drift align using the PHD routine (obviously you cannot do this unless you have a suitable autoguiding or similar camera.
6 Do a final 3 star alignment. Ignore what Synscan says about my Polar Alignment at the end of it, if PHD drift is OK, I am happy with that.
Doing this I seem to get pretty good PA and targets are always on the chip of my DSLR and usually very near the centre.
