Those altitude lock bolts on the alt adjust (each side of the mount ) ?I found, shifts polar align when you tighten them! ? Just a little but noticeable. ?It causes a little ?“twist” of the mount pillars for alt which shifts it in Alt and Az….enough to be annoying.?
?
its a bit of a bugger. ?You could note the “twist” error direction and amount and deliberately leave an offset so doing up the bolts “twists it into good polar alignment”! ?
?
Alternately you can buy cam lock levers of correct thread (Also use washers under the levers). ? These cause less “twist” when locking down, so polar align ?remains less effected when tightening.
?
There are other ways. ?Some users don’t tighten these lock bolts much at all !
?
I don’t think they need excessive tightening but maybe other users have some good ideas on this?
