I believe, would be slight field rotation over time.

So, who's right?

Hi Davoud:

Leveling is not at all necessary for an accurate polar alignment. It will help
with a goto scope during the initial acquisition of alignment stars, but even
there, once the scope is aligned it does not make any difference. Your goal
should be to design a pier that's as vibration free as possible.
