So when I compared particular RA/Dec numbers on the Audiostar screen
The Audiostar uses cut down equations of motion to calculate the positions of many things. It also doesnt do precession calculations, and as such what it reports will differ from a fully up to date phone/pc app that can use all the latest data and calculations.

the vendor only reloaded handbox firmware, so it's still the same new handbox hardware, as purchased.
Understood, there is nothing you can do re the hardware.
That said, there are big differences between some of the firmwares.

Lastly ... Is this an ETX-90 problem only,
For not being able to select an ETX-90 correctly, yes, it only applies to the new units with the plugs in the fork.
As per the other thread, ( and as suggested by Meade ),selecting an ETX-80 will get the correct ratios so it points correctly, but thats just a cop out by Meade. They should have fixed it by now.
