Polar Alignment Using The Star Drift Method . Articles | ... This method with, a little practice, can give you reasonable polar alignment within one half hour. ... If the star drifts northward, your scope is west of the pole. ... Remember that as your adjustments get you closer to the pole, the star will drift slower and you must wait longer to detect a north-south drift. If the star drifts south, you are east of the pole and you must turn the mount towards the west. ... www.astronomy.net . ...
