Book, Practical Astronomy from your Calculator by Peter Duffett-Smith
This is a great book for those boffins who like to do their own calculations. Although it says “From your calculator”, all these routines will work flawlessly when entered into a Spreadsheet! I’ve included the contents so you can see if your pet project is included. Putting these routines into a spreadsheet saves trolling through the internet to do calculations.
Postage $9.50
Book $20
