Gregg, I will check that. Great suggestion.
Make sure that the driver has the correct Longitude; I seem to
recall having a similar problem when moving my AP900 to a new
location and the longitude kept reverting to East instead of West.
I think I had to rename the location and save with a power off.

THEN the weird part: I hit menu till I'm at the top menu, I
select Object then pick some object I know is up in the sky
(I'm in a dome shielded from any risk of pointing at the sun
and the scope is covered anyway). Let's pick Venus for example
(tho it failed on the moon when the moon was up also). In most
cases the hand controller declares the object I can see naked
eye (Venus, the Moon, Betelgeuse, ...) is below the horizon.
Or it slews and slews way off the target.
Is it possible my hand controller db is corrupted from the
long time powered down?
