I noticed that it will guide your viewing to particular celestial objects through its motors.
But it can't track??
Is this correct?

The Argo is a "passive" device. It doesn't "move" anything at all - once an initial alignment procedure is carried out it merely knows (through the encoders Eric mentioned) where your scope is pointed at any one time. If you wish to go to an object that you've searched for and found in the database the Argo will tell you which way to push your scope, and how far, to get to it. Counters will appear in both alt and azimuth planes that will decrement to zero as you approach the target. It's very accurate. This is what you hear referred to as "PUSH TO", as opposed to "GO TO" which is what scopes fitted with slewing-speed motors do. Given that, the Argo wont make your scope track unless it is already fitted with tracking (clock-drive) motors, with which nearly all Dobsonian-mounted scopes are not.
