The mount has normal motor drive and does not have an auto-guider port. It is different from the standard GP mount only in that it has a ball head which allows the installation of a camera and a built-in polar finder. According to the manufacture, the running accuracy is in good enough to track using a camera with a standard lens for up to 30 minutes without error, assuming accurate polar alignment. Using a 200mm focal length lens, about 5 mins are possible.
