Agreed, the old way was completely unambiguous. Why they changed the East/west method is beyond me....
Simon, Ernie is correct. Let your camera do the work! Do automated T-Point runs of at least 45 points, run the super model, and then make polar adjustments. If you run less than 45 points or so the results will start to be contradictory from one run to another. Patrick Wallace has stated that T-Point is not iterative; that is, if you follow the recommendations exactly the mount should be aligned perfectly. The great difficulty is that what you input to the mount in terms of movement in azimuth and elevation may not be accurate enough. You might get a recommendation to move by 1.4 tics. You may think you moved it 1.4 tics but the reality is that the mount probably only approximated that move. So, yes, repeating the process over a few times does get you closer and closer, but then the adjustments also get harder to do and you can end up chasing your tail so to speak. When you get really close you might try using the camera to confirm the move was accurate. For example, you get a recommendation to move the mount up by 45 arcsec. Try using the slew command and move the scope 45 arcsec down. Then adjust the mount up and compare photos. Using this method you can get closer than you actually need! There are more details on how to do this on the SB site. Ernie put me onto this method and it really works well once you figure out how to do it!
