    Sigh... after fiddling with the sights and trying to find what
    altitude for a given time and AP gives a plausible distance to the GP,
    it seems there is about a 1.3 degree error between my recorded
    altitude and a more reasonable altitude.  The problem is my altitudes
    are all too high.  If, as has been proposed, I was using the top of a
    distant mist bank or cloud bank as the horizon, I should have
    altitudes that are too low because I'd have measured from Betelgeuse
    to the top of the clouds instead of further down to the true horizon.
    Instead it looks as though I used some point *below* the horizon as
    the "horizon" for my shots.  I'm hard pressed to explain that much
    error.
