[Saturn488]

I finally have my permanent pier all complete and wanted to ask about what can knock out the polar alignment.

I always bring the telescope in at the end of the night, I never keep it outside. What could cause polar alignment to be knocked out a bit from night to night despite having a pier?

Possibilities
- Ground/slab could be shifting but there are no signs of it moving as I have checked it
- The fact that I remove my telescope after every session and putting it back on
- Possums possibly playing with the pier!

I have had to re-balance everytime now as I am still tuning my setup still, that could be doing it too?

Would tightening the alt/lat bolts help as well cause I have read that there is no need to have them real tight?
