Celestial navigation is an essential tool for those who do not wish to be caught short when modern technology fails. The basic process is simple - take a sight with a sextant, establish a secondary reference or benchmark sight, compare the two sights and plot the result of the comparison on a chart. Schlereth demonstrates how to take sight by the sun, moon, stars and planets, discussing the advantages of each method. The reader is taken through several examples and situational illustrations.
