I'm working on applying some setting circles on the mount of my lightbridge. I
was just wondering what is the best way to align the azimuth axis? Some things
I've read about are aligning to north with a compass, or to align to Polaris.
Which is the correct way to align the azimuth setting circle?

You'll want to use Polaris. Point scope at Polaris, and set your aziumuth circle to 0.

I use Polaris as well, although I've heard of people trying to use compasses with varying degrees of success. Using Polaris is a piece of cake.

Also, make sure that you have the scope's base level. If it's not level (or close to it), then every thing will be slightly (or not so slightly) off when you're trying to locate objects.

Good luck - setting circles was one of the best things I did for astronomy.
