Hi Bruce,
Thanks for your input. Very helpful to know that I'm not alone. Interestingly you are using the exact same mount.

The problems you are describing with rotating forth and back are exactly the same that I observed. Only when I had a bit more patience yesterday to systematically analyze what is happening I noticed that a Meridian Flip is being reported during PAA. So one of the things I tried was to dectivate what I consider is triggering the Meridian Flip in KStars/Ekos after trying a number of other things.

When deactivating the flip in 3.5.6 the error I see as a result from a PAA run is different about 3' to what it gives me in version 3.5.2. Not so far off but hopefully the development team could confirm if there has been a change which could explain thus and maybe the new version is more accurate.

With the alignment adjustments I did based on 3.5.2 I made some test shots (with 3.5.6) of M31 (knowing well that clouds will stop me) and achieved a total RMS in the guiding of around 0.6" which is the range I usually target for. So the 3.5.2 guidance for the polar alignment of the mount has been surely not too bad. I ran out of time to adjust the mount in line with the 3.5.6 PAA results to be able to compare as clouds rolled in....

Kind regards,

Alex
