I have considered the following 3 options and would like to hear thoughts.
1. Sbig AO-7 / AO-8 (however I do fear that I will get the same good performance during exposures and then having it go crazy during image downloads.
2. Qhy5 or the like via an OAG or external guide scope.
3. This is a bit of a long shot shot.. But how about guiding the mount via a Qhy5 and external guidescope while using ao7/ao8 @ 7~8hz to chase seeing
My sbig doesn't have a remote guide port.. I need to spend more time at the scope hopefully this week to determine the cause of this problem however I honestly feel there is some interference somewhere causing the camera to feed the mount a 5 second long guide correction during image download.
Any thoughts.

What software are you using? because it seems to me you are inventing expensive ways to fix a trivial problem. Most packages have either "exposure delay" or "wait for guider to settle" parameters, which will stop the camera exposing before the guide is back on tasl
