More likely the assembly is not squared on, with the tilt in the focal plane being
compensated for one side of the pier via flexure, but exaggerated on the other.
Just my 2 cents worth....

When you say assembly do you mean the scope or the scope and its mounting plates etc or the mount?
I agree its unlikely the mirror or tube of the scope is flexing. I reseated the worm gear on both axes tonight (it takes just a minute thanks to clever AP engineering). The mount's slewing sound did sound a little better. I did manage a 10minute sub with scope on the eastern side and round stars. But
cloud suddenly appeared stopping proceedings. I'll check the secondary ring as well.
I have gotten round stars on either side plenty of times in the past and other times its was polar alignment off etc, usual stuff.
Thanks for all the replies. Sometimes these little flexures are hard to track down.
