Re: OTA Orthogonality, and Polar Align


I too have owned only one other GEM which was a Celestron CGE.
To get accurate GOTO's good polar alignment was not required; but having the

I have an AP 900 ver. 4.07 and get the impression this is just the reverse
Polar alignment is more critical, or how important is leveling?
Also, is it highly recommended that I upgrade to the latest firmware?
