Has anyone ever run 2 cameras - one for the OAG & another
for the SX-AOL which would surely give even better pics?
( Then the SX-AOL would never go out of range. )

Yes I did guide once with a QHY5 on a finder 8x50 with PHD. Then had the AO doing its thing with the lodestar. That was on a C11 at prime focus.
The thing is that the AO never goes out of range. 50%/50% is centered. You select a threshold so if it hits let's say 30% or 70% on any axis then the mount is bumped. The bump doesn't affect the AO because it corrects faster than the star shift. TBH guiding with another camera didn't improve anything. Just more USB and power cables to worry about,
