    Re: A ramble on "new improved methods"

    Brian,

    For a tabular time sight I find the Bernecky improved Martelli tables easiest to use and mistake free. For me the quickest most accurate way to do a time sight is with a trig calculator (Casio fx 300es is a good one) and the formula :

    Arc Cos } (sin lat sin dec +/- sin Ho) / (cos lat cos dec) = (t) LHA   

    same name -

    contrary name +
