    Re: Using Polaris to check sextant sights.
    From: Gary LaPook

    When using the times of meridian passage from this web site work out
    the time of passage for your location using the normal procedure and
    then compare your time with the listed time for the same date to
    determine an offset which you can then apply to the other listed times
    for other dates. Much easier than computing it the normal way over and
    over again. For my location in California at 118� 54' west my offset
    is minus one minute 45 seconds for the local date.
