Once you polar align your scope, in my case using an illuminated reticle polar alignment finder scope carefully aligned with my LX90, and you go through the set up to align the scope with the sky, is there a way using autostar to "tweak" your polar alignment by having the scope zero in on Polaris and see how for off center it might be? Or any way other than drift align to make any improvments using the software?

I've done the PEC step, trained drives, and I get corrections of x=.3 y=.4 or less when guiding with the DSI Pro on my guide scope. Seems good for sub frames up to 4 minutes some up to 8 minutes.

A drift alignment is best.
If you can guide ok at 4 minutes then 8 minutes should be good.
