    Re: Buying a sextant- a cautionary tale.

    The distance in the Orion belt I posted
    was NOT corrected for refraction.
    That's why I did not include time.
    The refraction correction is actually negligible
    in this case because the distance is small,
    the altitite is not large, and the pair look almost
    horizontal from our position.
