I covered this briefly in my article. SharpLock relies on the ONAG because of how the guide star appears in guide camera through the ONAG -- approximately cross-shaped (+). When out of focus, the cross will appear wider or taller depending on which direction the focuser needs to be adjusted to restore the symmetrical cross shape.
In a ordinary OAG, the star would appear very much the same as it would in the imaging camera (hopefully round), leaving SharpLock without anything to work with.
Maxim allows 3rd party programs and plug-ins to connect to and access it's cameras. (AstroTortilla makes good use of this, as does SharpLock).
