You can get well within 1/2 degree during the day with a little app called 'Solar Polar Align' and a cheap digital angle finder.
With no scope, set alt adjustment at 0, so the dovetail saddle is flat and put the phone on it where the scope would normally go. Solar Polar Align' computes the shadow angle of a vertical object, so you adjust the Az to make the shadow and line on phone match. It is much, much more accurate than a compass.
Then put the angle finder in the saddle and set the Alt to exactly where the angle finder matches your latitude. Now attach the scope.
Come nightfall, fine tune with SharpCap, but at least you will be starting out extremely close to true north.
Keep in minds, polaris is not exactly at the pole and there will be some cone error with the scope, so you may not actually see polaris through it, but the important thing is to align the mount to true north.
