The North Star is the best. even tho it itself is a little off from
exactly North also. But less than a degree. About 0.6 degrees or so.
If that isn't accurate enough there are tables you can look up to learn
what we call cumulation of Polaris. This is a time when Polaris (AKA The
North Star) is directly above or below the pole. and then would give you
an exact AZ setting, then 6 hours before or later Polaris would be east
or west of the pole exactly and this would give you an exat elevation
setting.
Never use magnetic readings. depending where you live it can be a LOT off.

What I do ( and I'm not sure I'm right,but seems to work ) is to use the
North star to calibrate. I live at 41.2* latitude, so if I crank my
antennas to 41* elevation and point north 0* azimuth I should be pretty
close. I also live at 1* magnetic declination, not much so I don't worry
much about that. Now I don't do much EME as I don't have any power, but
I've monitored EME and this seems to get me pretty close. I will also be
glad to see what others do to calibrate.
