A fully automatic mount would have to be Alt-Az because such a mount, not having a polar axis, does not have to be polar aligned. It can be plonked on the ground with a roughly vertical azimuth axis and software can figure out it's position by platesolving several images taken through a small finder scope that is mounted parallel to the main instrument. That is the easy part. The difficulty comes from the need of a third computer controlled axis, to do the field derotation for imaging. Such a derotator needs to have high resolution and be backlash free - not easy or cheap to achieve.
Then you have the problem of rotating spider diffraction spikes in the subs if the scope has spider vanes.
