I do not have a clue.  It is an interesting question, though.

If someone else does not post with an answer, that would be a good thing to ask.

It might give someone an idea of things to do to make the system better.

From everything that I've read and heard, albeit limited to what's available on the internet, the LX800 will automatically acquire a guide star (as low as mag 11) as soon as the slew completes. With that being said, it certainly sounds like, in this scenario, that the LX800 will acquire a new guide star (not back to the original) once the slew completes. Here's a link to the video where I found this information:

I have another LX-800 related question. I have one on order, I also have the zero-image shift Micro Focuser and have also ordered the F5 fieeld Flattener/Reducer.
In this configuration, would the Focal Reducer be attached to the rear-cell of the scope, and the micro-focueer be attached to the F5 reducer, or will the Micro Focuser go onto the rear cell first?

Somebody correct me if I am wrong, but I believe you would want to hook the microfocuser on first.  Putting the focuser between the the focal reducer and imager or eyepiece would change the magnification.  Not sure what it would do to any coma correction.

I would have thought so too, but a guy at Mede Support said the reducer should go on first -- it didn't seem right to me -- I'm kinda hoping that someone in  "the know" would step up and clarify this. Since the Micro Focuser gets 'Locked onto' it's mount point (via set screws), you would think that would mean it is there for keeps, and reducers and other visual parts would come after...
