A great reference
on 25 January 2012
This is a great book for calculations that are relevant to astronomy. It covers aspects of calendars and time (Julian dates, sidereal time, ephemeris time etc), the major coordinate systems (and conversions between them), as well as the positions of the Sun, Moon & planets. Despite being a book of calculations, it does come with some background information on the topics covered to set the scene in each section.
Like a culinary recipe book, I tend to come to this book already knowing what I want to do (e.g. calculate the position of the Moon in the sky) and then just follow the appropriate calculations. The recipes sometimes require you to refer back to previous sections but they are always clear to follow. The worked examples are also very useful to check against if you've transcribed the calculations into your own software.
All-in-all a nice update to the original edition.
