Celestial navigation is a way to find your latitude and longitude
on earth using a sextant to measure the angular heights of
celestial bodies above the horizon. It has been used by mariners at
sea and explorers on land for three hundred years, and it is still
used today as a dependable backup to modern electronic navigation.
Routine celestial navigation relies upon accurate time (Universal
Time) to find the longitude of a position (latitude does not
require time). Advanced celestial navigators can find longitude
without knowing the time using a technique called Lunar Distance.
In this technique, the sextant is used to measure the angular
(diagonal) distance between the moon and another celestial body.
Since this distance slowly changes as the moon moves eastward
though the stars, it can be used to find the time of day that is
needed to complete the longitude determination.The process of
finding longitude from lunar distance, however, requires special
tables that have not been published in the Nautical Almanac or
other sources since the early 1900s. Although software solutions
have been available, most advanced celestial navigators are very
grateful to navigation historian Bruce Stark for creating these
printed tables dedicated to this task. They have been used and
tested by mariners for more than 15 years and are praised by
experts for their ingenuity and ease of use in solving this complex
navigation exercise-which all agree is the hallmark of an expert
celestial navigator.With The Stark Tables in your nav station, you
no longer have to fear losing power to your electronic navigation
aids, nor are you dependent on accurate time from any official
broadcast.Besides their practical use in back up navigation,
historians have used these tables for years to interpret the
logbooks of Lewis and Clark, David Thompson, James Cook, Matthew
Flinders, George Vancouver, Nathaniel Bowditch, and other notable
explorers and sea captains."It is remarkable in this day when the
very survival of celestial navigation seems in question, that an
individual should suddenly appear on the scene and present to the
world such a brilliant piece of work. Stark has rendered a great
service to the celestial navigation community." - Robert Eno, The
Navigator's Newsletter"Captain Cook would have relished using these
tables, had they been available to him then."- George Huxtable,
