THE ASTRONOMICAL ALMANAC(S)
Produced every year by the US Naval Observatory and the UK Hydrographic Office, these detailed and highly-respected guides have been used to test and confirm the accuracy of the products and other offerings available here on our website. They have also been used to confirm the accuracy of CELESTIA itself.
Written by Jean Meeus, the highly respected "part-time" astro-math-wizard whose contributions to the field of "computational astronomy" are legendary, this book is considered a "landmark" on the subject. Our following creations employ algorithms from this superb work: Solar Eclipse Finder, Lunar Eclipse Finder and "celeSTARrium".

3D MATH PRIMER for Graphics and Game Development
This impressively comprehensive review of 3-dimensional math concepts and theory was helpful during the development of the CELX / LUA code for "celeSTARrium" in particular. If you want to gain an intuitive understanding of vectors, matrices and quaternions, here's a good place to start.
