I have the same GoTo mount and I am not sure, but I seem to recall seeing "Polaris Australis" on the list at some time.
I looked on the net but couldn't find a SAO number for it, otherwise it is also known as HR7228 or HD177482 but I couldn't find anything that would link any of these to a SAO.
At the moment, I only do visual alignment and what the reply from Celestron seems to backup what I have found, haven't tried drift alignment yet. You can go to something and it is pretty spot on. Leave it for a few minutes while I go inside to get something I forgot and it has moved significantly, ie "drifted". But select something else and it is spot on, actually it would be interesting to go to something, let it drift for several minutes and then go to it again. I expect it would actually put it in the middle again. Essentially from what Celestron says, the mount uses both motors to go to an object but once it has found it, only one motor is actually moving. I imagine if it is a fork mount, it would track in both directions, but of course if you are shooting near the pole you will get a lot of "rotation" of the image.
