I think it represents the state of the art at the time, but recognises the issues involved.
Why do you say:
""There is also no mention of having and maintaining the alignment of the main imaging telescope coaxial with their polar aligning scope and camera.""
Based on the current plate solving methods - SharpCap, PPS etc it is the mount's rotational axis which is critical - the actual imaging scope doesn't have to be aligned with polar axis......
