    Body not aligned with reflection in artificial horizon
    From: David Cortes
    Date: 2007 Nov 23, 12:52 -0800

    Even after adjusting my sextant as well as I can for perpendicularity
    and side error, I still have the following problem when using an
    artificial horizon:  When I bring the body down to the horizon
    (regardless of whether it's a pan of water or a mirror), the "brought-
    down" body is well to the left of the body reflected in the artificial
    horizon.  Have I not corrected enough for perpendicularity?  What
    other error might this be?
