abstract:A star catalogue, or star catalog, is an astronomical catalogue that lists stars. In astronomy, many stars are referred to simply by catalogue numbers.
His own starcatalogue, the Historia Coelestis Britannica, was eventually published posthumously by his wife and co-observer at the Observatory, Margaret Flamsteed, in 1725.
So in 1712, Newton, by now president of the Royal Society, together with the indefatigable Halley, again obtained the data by subterfuge, and published a pirated edition of a new starcatalogue.
The first Astronomer Royal, John Flamsteed, compiled the most accurate starcatalogue of his day as part of this attempt (though the solution was eventually provided by John Harrison, a clock maker who designed a timepiece that was robust enough to withstand the rigours of sea travel, and was thus able to substitute for the stars in the relevant calculations).
