Product Description
Review
"This is a work which all amateur astronomers will want to possess." Times Higher Education Supplement
"This is one of the best publications of its type on the market today. The book is well written and illustrated. It is highly recommended." Journal of the Association of Lunar and Planetary Observers
"...an example of how wonderful a tool a computer and a few programs can be. With the subroutines in this book, the amateur astronomer can have more time to concentrate on the heavens and leave the earthly work of astronomical computations to the computer....a good sourcebook for those amateur astronomers who are not afraid of some simple programming or for getting someone who is familiar with programming interested in astronomy. It could be useful to those who want more accuracy in their space games." William H. MacIntosh, Computing Reviews

Product Description
The first edition of this very successful book was one winner of the Astronomical Society of the Pacific 'Astronomy Book of the Year' awards in 1986. There are a further seven subroutines in the new edition which can be linked in any combination with the existing twenty-six. Written in a portable version of BASIC, it enables the amateur astronomer to make calculations using a personal computer. The routines are not specific to any make of machine and are user friendly in that they require only a broad understanding of any particular problem. Since the programs themselves take care of details, they can be used for example to calculate the time of rising of any of the planets in any part of the world at any time in the future or past, or they may be used to find the circumstances of the next solar eclipse visible from a particular place. In fact, almost every problem likely to be encountered by the amateur astronomer can be solved by a suitable combination of the routines given in the book.

I can't believe this book is still available
27 Mar 2006
Format:Paperback
I own the original 1985 printing. I bought it for use on my AppleII+ probably back in 1985.
All the code is written for very basic BASIC. Yes, it is all suppose to be written as ONE program. The code routines all use GOSUB's. None of it is written for todays BASIC, or even older Basics like QuickBasic. Trying to translate or port the routines to todays languages is nearly impossible. First, it only supports Integer numbers, no floating point, so there is high inaccuracies in the calculations.
You would spend more time trying to translate this code then you would going it from scratch.
This book is too outdated to be of any use on todays computer languages. It was great in its day - it's useless now.

excelent but Sadly out of Time .
26 Dec 1999
Format:Paperback
Although the book covers a great range of astronomical programs, its psudo-code doesn't make for easy translation into other landuages like C++ or Pascal. He goes through the program one by one, but one can't help but feel it was ment to writen as one big program. Not for the novice astronomer or programmer.

Excelent book with clearly commented source
23 Sep 2008
Format:Paperback
I bought this book out of curiosity, and found the functions fun to play with. I ported some of them to 16bit assembly language and had to make a floating point adder as this book uses a lot of real type numbers. However, the code may not run in newer Basic compilers like Qbasic as the syntax is more for AppleIIe/Commodore 64 basics. So some porting will be necessary.
