If you are not changing your location too much, let's say, maybe a few degrees north or south, do you "locate" your telescope just on a few stars or do you use polarscope for most accurate positioning? And how accurate your mounts are? Best regards and clear skies.

I just rough align on Polaris and then do a 2 star alignment and I'm good to go.

The Argo Navis pointing model gets me to within three to four arc minutes of an object. The pointing model indicates that my polar alignment is typically from 0 to 15 arc minutes of true N, within the measurement error of the encoders.
