Thanks for the interesting post, Luke.

According to posts by Doug George on the Maxim group this is intended behaviour. The USB traffic required to continue guiding has been known to cause artifacts in images downloaded from the main imaging camera. Personally, I'd prefer this to be an option that can be turned on if needed.

Guide star selection is automated and the user cannot manually select the guide star.
A really dumb program feature in my opinion.

Yep, the automated guide star selection in Maxim sucks

As Peter pointed out you can override this, but my experience was that while it works for guiding with the AO, it doesn't work when calibrating it. Maxim would let me select a guide star but as soon as I pushed the button to calibrate it would go and select a new one.
I made an attempt to compare OAG and AO guiding here:

I was hoping to perform some more tests, but between a long holiday and rubbish weather I haven't had a chance...
