Drift alignment is the way to go if you're imaging.
I use the ccd drift alignment method which I find very accurate.

A member here, Robin has written a cool program that automates it using Maxim and EQAscom.
If you're using the hand controller, you can adjust the brightness of the polar scope light with the hand controller settings.
These articles in the the projects section are good as well
