I have an old manual that makes the fact that magnetic and polar north are not aligned everywhere.?? The earth's core generates a magnetic field that wanders (there was an article recently showing wandering at a rate of several feet a week,? if I remember correctly) so you align your compass to magnetic north then make a correction based on the latest geomagnetic map.?? So,? in my area, I note magnetic north then move the compass left or right by the offset degrees for my area.?? If you want,? I'll dig it out and and post it here

This is for anyone who
regularly ¡°goes mobile¡± to do Astrophotography.. How do *you*
determine how to initially place the tripod??
?
I envision putting the mount
in the center of the Azimuth adjustment range, but when you go to a location
you have never been before, how do you determine where the tripod should be
pointing?? I would be seriously bummed if I assemble the whole system, tried to
polar align, and run out of adjustment so that I would have to disassemble and
rotate the tripod..

Can you just place a compass
on the tripod and use that, taking magnetic declination into account?? I would
think the metal in the tripod would make the compass inaccurate??

Anywho.. I would like to
know the various methods people use..
