If the scope thinks it is aligned ok, but in reality it is pointing that far off from where the target object actually appears, that to me seems to suggest that the scope may think it is sitting somewhere else, ie not in Adelaide. I don't know if your telescope needs latitude & longitude or some other positional data (name of town?) as part of it's setup but it sounds like the position may be out - worth checking?


EDIT : Looking at those error figures, and running things through in my head, I tried a little experiment in Starry Night.

You said that

when I asked it to point at the moon it was about 10 degrees low and 14 degrees south
(I assume "it" meaning the telescope was pointing low and south, not that the moon was low and south)

Starry Night gave the moons position at 9pm tonight in Adelaide as Az 258° and Alt 28°.... that equals 9.30pm Brisbane time, and if I switch to Brisbane as a viewing location at the exact same moment it seems that the moon would be found at Az 249° and Alt 14° ....

In other words if the scope thought it was in Brisbane, but was actually in Adelaide it would point 9° low and 14° south of the moons actual position at 9pm Adelaide time, pretty damn close to the "about" 10 & 14 you quoted.
