    Re: azimuth bearing on celestial bodies
    From: Jim Thompson

    I often use precalculated altitudes to find a body.  I just sweep the
    horizon in the approximate azimuth.  I do use a handbearing compass to
    orient myself, I think that your Silva should be just as precise in this
    situation, given that I usually only need to be within about 5-10 degrees.
    It's not likely that I find two magnitude 2-3 bodies at the same altitude
    within a band that narrow, even given the 5 degree altitude error range
    using 2102-D.
