The motorised Rowan Az-100 prototype looks good.
Pics show motor housing covers removed.
According to Rowan: The mount will have it's own motion controller with WiFi and GPS that will operate stand alone, with Sky Safari or Nexus DSC. Slew onto target will be manual as operating manually, then the controller will track the object in the FOV. With the object position being passed from Ski Safari or DSC to the motion controller, if the manual slew results in the object not being in the FOV, the controller will position the object in the centre of the FOV and then continue to track.
