As Dennis has pointed out, your talking about P.E.C. I was reffering to Drive Training. So in this mode the scope does not rotate (Track stars), the R.A and Dec motors are turned off. This needs to be done so a backlash compensation plus some other minor info can be calculated. So picking a star is useless as the star will drift across the eyepiece, and so pointless doing it.
You need a stationary object. I use a house about 500 meters away, and line up the window (Nice painting he has on the wall too.).
Drive Training makes a very big difference.
So it really needs to be done before you even try polar alignment or P.E.C.
