    Re: making your own almanac
    From: Paul Hirose

    "Astronomical Algorithms" by Jean Meeus has formulas for computing
    celestial body positions. It's one of the classic references for
    hobbyists. (So is his earlier work, "Astronomical Formulae for
    Calculators".) However, I'm not sure if his methods can match the
    Nautical Almanac's 0.1 arc minute accuracy.
    
    There are implementations of the JPL planetary ephemerides available
    online for free. These can replicate even the Astronomical Almanac
    tabulations to full accuracy.
