Electronic navigation has bought undoubted benefits to all navigators, however it is very reassuring to know that one has the skills to be able to navigate to one's destination if the electronic equipment should fail in mid-ocean.
This book is a self-teaching course that takes the reader through the basic skills needed to take sun sights, and then plot a position. At each stage of learning there is a summary of the facts as well as exercises to test understanding, before the reader progresses to the next stage.
It has to be said that this book follows the conventional path throughout in presenting and teaching celestial navigation, and therefore will fit most comfortably with other, supporting references.

CELESTIAL NAVIGATION IN THE GPS AGE.By John Karl. Paperback, 172m x 253mm, 273 pages, illustrations and tables.
Celestial navigation is a crucial skill for the offshore navigator. This book provides the shortest path to acquiring the skill.
Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the students along quickly. This book tells the true story - and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.
It's tailored for navigation in the GPS age - a time of computers, calculators, and web resources. Although it covers all of the traditional methods of "working a sight", the primary thrust is using the scientific calculator. Using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.
In addition, you will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell time from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas.
This may not be the only book you read while learning celestial navigation, but it certainly should be one of them.

CELESTIAL NAVIGATION DVD - FOR THE COMPLETE IDIOT.By Safe Boating Series. DVD.
Hundreds of years ago, Celestial Navigation was considered a national secret, because the country that could navigate could find the best trade routes and would also be able to have its naval fleet rendevous for battle.
Nowadays, utilizing the developments made by Nathaniel Bowditch and John Harrison plus newer sextants, computers and quarz time keeping devices, celestial navigation is available to every sailor...but for some reason, the old mystique seems to linger.
The purpose of this program is once and for all to de-mystefy the subject, and clearly explain how it works and what it does, in plain English.
Skipper Gene Grossman covers the entire subject, from comparison to Coastal Piloting, to the various methods of navigation using all the celestial bodies...and if you watch all the way through, you'll see the surprise ending that will show how to change the cover and graduate you from "idiot" to "Navigator".
