    Re: An azimuth formula that works everywhere? Even on poles?
    From: Geoffrey Kolbe

    The problem in taking an altitude of Polaris while standing at the North pole is - what direction do you face? Normally, an object is low enough (in altitude) that there is no problem, you stand facing the object. But when the altitude approached 90° then this becomes a significant problem, wherever you are on the planet, and can lead to significant errors. Of course, whichever way you face at the North Pole, you are facing South, which somewhat adds to the problem.
