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

    Re a zenith fix on Polaris at the North Pole:  One further thought, the closer to the Pole you were, the less accurate your watch could be, and at the pole itself, you wouldn’t need a watch at all, because Ho would be constant at 89 20.1’ (according to ‘Navigator’) give or take a year or so.  The PZX triangle would now a be 39.9nm line rotating around the Pole.  Perhaps they could try it with Sigma Octantis at the South Pole Station. That line would be 63nm long.  DaveP
