[.ca] Celestial Navigation: A Programmed Learning Course (ISBN 0713658126)

easy to follow:
Starting from the basics, this book allowed me to get a grasp of the fundamentals of celestial navigation. It concentrates mainly on obtaining a position from the sun, and very little space is devoted to moon and star sights. That being said, the examples are very clear, and the process made understandable. This book needs to be re-read, but it can be taken up again from a position of certain knowledge, and so strengthen the knowledge gained. All basic questions are answered, and practical advice is given. I liked the format, and found the line drawings clear. Examples were well worked, and at the end of it, you get the feeling you could actually take a sun sight and fix a position. Try it!

Not a programmed text:
The title sounded very promising. Following this "programmed text" was very frustrating. Texts like this give programmed instruction a bad reputation. I would not recommend this book.
