    Hi Gordon,
            There is a book called "the Calculator Afloat - a mariner's guid to
    electronic calculator". This book provide you with formulae and data for
    calculating GHA, SHA and Declination for Sun, Aris and Stars from 1979
    to 1999.
            I had use this formulae in 1984 to write celestial navigation programs
    for private use on board ship. They are very accurate and within an
    acceptable range when compare with the Alamnac.
            My homepage that setted up in June this year basically use these
    formulae and JavaScript to convert my old programs and make them
    available on the WWW. You may have a visit and check the results. I have
    not yet get time to code the part for stars which I worry will take
    another month before it could be completed.
            The address is http://www.speednet.net/~himarj
