Description
The famous set of mathematical tables was first published in 1803. It has been a bestseller ever since, and despite developments in electronic navigation it remains an essential requirement for anyone learning and practicing astro-navigation. Last updated in 1994, the editor, George Blance, has worked for some time on the modernisation of all the tables for this new edition. New tables have been included, obsolete ones deleted to conform with changing techniques of navigation, with the aim of improving the accuracy of the calculated position and reducing the tedium of the calculation.
