Thanks chaps. CWD= counterweight down. I know balance is not an issue as I spent quite a while getting that correct. My guidescope is an ED80, and the guide camera is the Orion Starshoot Autoguider.
Marc, not sure as the what you mean relating to the image scale +/-??
I know the clutches are dry and clean as I did them with the service. Drift alignment should be pretty good as I have registration marks on my pier/mount, so it is just a matter of plonking the mount back on the pier and aligning the registration marks. If it is out, it would only be a poofteenth, and should definitely be able to be corrected by guiding. Also the fact that the mount does not end up in the proper parked position has me stumped as well.
