The Half Hitch was designed from the outset for computer-assisted pointing.  The integrated 4096-count optical encoder installation on the Half Hitch is perfect:

• The axes are accurately orthogonal (at right angles)

• The encoders are precisely aligned to the centerlines of the axes

• The axis bearings have essentially zero run out

• Machined housings that blend smoothly with the elegant contours of the mount

There are no cables to wrap, and the DSC bracket positions the control panel within easy view and touch.  When it's time to pack up, the DSC bracket folds neatly along the side of the mount with the DSC unit in place.  The Half Hitch travels small.

If a mount was not painstakingly created for computerized pointing, any attempt to add-on this capability will be frustratingly poor.  It's virtually impossible to retrofit an accurate encoder installation onto mounts based upon castings or welded pieces, or which have screws for axes, or which attach the encoders to knobs, or which offset the encoders to the side of the shafts.
