Good day Rodney, had a good look at all your files and TBH I can't see much wrong with the scope. That's what I would expect for that type of refractor with that level of scrutiny
Having said that how do you focus? Are you absolutely sure you are in focus when you get outer field aberrations?
Re:CAA it's very easy to fix. Pull it apart. You'll see there is no bearing or bush. It's only two parts extremely tight fitted. You need to pull them apart, degrease and clean them, then put just one drop of very thin oil and slide them back together then adjust the ring for tension. You'll then see you'll have no sag or play and it will rotate very smoothly.
