hi nick,
if you do the two star alignment - ignore the errors.
then do the polar alignment routine as listed in 11.3 - it explains it
better. and it will make sense when you do it. its good because you visually adjust the star to bring it into centre with the alt and az controls. you don't have to actually remember if its 'left' or 'right'.
