I would use a software program first. Something like Pempro's Polar Align Wizzard. Get the mount spot on the pole, preferably from the comfort of home. Pempro provides real time results, so you'll known when it's locked in. Then make physical adjustments to your polar scope alignment screws, as you look through it, to align the reticle on the appropriate stars. Then, and only then, would I trust a polar scope for polar alignment out in the field
