Similarly, the apparent complexities of the  solar and stellar systems take on a less  frightening appearance when related to the  lighthouses and similar earthly objects used for coastal navigation. Throughout this book, the  author uses such a comparison between earthly  and heavenly objects in explaining the close  relationship between coastal and celestial  navigation. In doing so, he reduces a complex  subject to a simple and interesting one that can be absorbed by even the most non-mathematically  minded. The book concentrates for much of its  length on the plotting of the boat's position  by sun, planets, and stars when out of sight of  land. It also deals with related navigational  routines such as checking the compass by using  heavenly objects, taking radio time signals, and adjusting the sextant for day-to-day corrections. This is celestial navigation in its simplest  form, presented in a way which even the most  amateur navigator can understand and absorb.\u003c\/p\u003e\n                        \u003ch3\u003e\u003cstrong\u003eAbout the Author\u003c\/strong\u003e\u003c\/h3\u003e\n                        \u003cp\u003e\u003cb\u003eJeff Toghill\u003c\/b\u003e is a graduate of the School of Navigation, Southampton University.
