From what I can see, the auto-tracking scopes have no database of objects is that correct? so there is no way to locate objects with just the auto-track version?
I like the 14" Go-To from skywatcher. I've also heard of the 16" coming soon (who knows when?).
Other than these options, is there another scope available in Oz that I've overlooked in the same price range ($3-4k) that still offers auto-tracking but perhaps uses push-to rather than go-to?
Cheers all

There is only one controller that I know of that can be fitted to a dob to make it track objects. It is the Tech 2000 DOB 11 driver. It uses a stepper motor drive system and to make it track you look through the scope for two or three minutes at your selected object and use the controls to keep it centered. After this it works out a track rate and direction and then follows automatically.
I have had one keep an object in view for over an hour. It uses friction drives that are easily disengaged for normal push operation.
It does have a way to connect it to the older computers that have an LPT port to make it into a Goto telescope complete with database of objects.
With this controller you can also use an Argo Navis to supply DSC's for object location. However the cost of attaching these accessories to a DOB will probably be more than a similar sized DOB with a goto already fitted.
