Astro Navigation Demystified Volume 2, Revised Edition July 2012 - suitable for all Kindle types including Kindle-for-Ipad. As the title suggests, this book aims to make the art of astro navigation easy and enjoyable to learn. It is written in plain language and seeks to dispel the aura of mystery which surrounds the subject.
This volume gives a detailed explanation of the use of the Rapid Sight Reduction Tables together with demonstrations and tests. Volume 1 focuses on theory and includes a clear exposition of the application of spherical trigonometry in the solution of astro navigation problems (search for Astro Navigation Demystified Volume 1 on Amazon).
The book is also available in paperback form and there is also a full kindle version which combines volumes 1 & 2 (search Amazon for Astro Navigation Demystified - Full E-book Version).
The author believes that astro navigation is not just for navigators; the subject is an interwoven mix of geography, astronomy, history and mathematics and should appeal not only to all who have a fascination with the sea but also to those who have an interest in education.
