    Hi Frank,

    Interesting.  I wonder what nationality this mate is?  I haven't met anyone who does celestial navigation this way.  It doesn't appear to be either the "American" or "British" schools of navigation.  I wonder how accurate his final positions are.

    Observing a star azimuth is possible, although I'd tend to use the alidade on the repeater over a hand compass.  It just takes a bit of time to do so.  At low altitudes there obviously isn't much change in time, so the error is pretty minimal.

    In my personal experience, I have found that stars under 10 degrees of elevation are generally un-reliable.  Likewise my experiments with moonlight sights away from twilight also yield questionable results.

    Jeremy
