Celestial Navigation - Book

Jeff Toghill's Celestial Navigation starts from a reassuring point: most of the math in modern sight reduction comes down to adding three lines of figures. He compares the sun, planets and stars to the lighthouses and other marks a coastal navigator already uses to fix a position.

From there the book covers plotting a position from the sun, planets and stars, checking the compass against heavenly bodies, using radio time signals, and making the day-to-day adjustments a sextant needs. It's a practical, hands-on introduction for sailors who want a backup to electronic navigation.
