    Because the orbit is curved, and the Earth rotating below it, the track
    is not "straight" (a great circle)
    A better approximation is a slightly negative declination, with the polar
    axis pointed "somewhere" above the horizon.
    You can find out where to point the polar axis by using three (or more)
    alt/az predictions (or convert RA/Dec to H.A./Dec) and compute(estimate)
    the point which is equidistant from "all"
    I wrote a program POLE.EXE to do this, and the issue was discussed on
    SeeSat-L twice a few years ago.
