If your guide scope is held only in 2 places, you will get differential flex. Needs to be held in 3 places. Take a look how we mount a guide scope:

Have to admit I didn't think of that, but am aware of the problem. I broke everything down and reinstalled the guide scope between the two sessions. I typically tighten those guidescope mounting screws good and tight, but that's another thing to check. I wonder if the mounting screws on the focuser itself or the guide scope mounting bracket have worked ever so slightly loose? That would cause the same issue. I'll check that too. Thanks.
