Duffett-Smith, Peter J. Practical Astronomy With Your Calculator Very useful book, covering time, co-ordinate systems, orbital systems and the Moon. A simple school calculator is adequate, as long as it has trig functions and a square root button. |
Meeus, Jean Astronomical Algorithms This is the book to get if you want to know how to do astronomical calculations. Meuss is the undiisputed master of this branch of astronomy. Highly recommended. (Out of priont but the link should indicate 2nd hand availability) |

Montenbruck, Oliver & Pfleger, T Astronomy on the Personal Computer With CD-ROM, including source code. Progresses from co-ordinate transformations toadvanced methods for planetary positions, purturbations, eclipses, occultations, etc. |
