Of course it retains the same unprecedented clear and accurate explanation of CN mysteries, such as the role of the assumed position , and how positions and celestial LOPs can be plotted with no assumptions. The section on stars has been expanded, and star and planet identification and viewing have been added. It explains nine special sights, such as Polaris sights, meridian sights, and even sights without a sextant. Lunar distance sights are explained from the ground up, using only basic concepts, with no special formulas or tables. The book has a unique chapter on sextants and their properties, explaining the workings and effects of different horizon mirrors and telescopes, and their associated advantages and disadvantages. Related topics include: integrating CN with GPS for improving skill and safety; constructing plotting sheets; making superior running fixes; designing special LOPs for landfalls; and performing compass deviation checks at sea. Beginners will like the clear and authoritative explanations, arriving at a complete sight reduction in just 40 pages, accompanied by 72 exercises for plenty of practice and confidence building all in the most comprehensive CN book ever written. Experienced navigators will appreciate the comprehensive fresh treatment of all topics, many never seen elsewhere.

This covers the sun, moon, planets, and only those stars whose declinations fall into this range. Volume 1 contains some stars (whose declinations may be more than 29°) that are pre-selected for optimum viewing and direction. This volume is applicable for an 8 year period, centered on its Epoch date. The only drawback to this arrangement, is that it is possible that a star may be observed that is not one of the pre-selected ones, and whose declination is more than 29° north or south. This star, if observed on some unlikely occasion, say through a break in the overcast, could not be computed using the 249 tables.

Sextants can also be used to find the correct Universal Time by measuring the angular distance between the moon and another body along its path across the zodiac. ÿ In coastal waters or on land, sextants can be used for very accurate piloting by measuring the horizontal angles between charted landmarks. The vertical angle of a peak above its baseline determines the distance to it, which, combined with a compass bearing, yields a position fix from just one landmark. The angular dip of an object (island or vessel) below the visible horizon can also be used to determine the distance to it. ÿThis booklet explains how to get the best results from plastic sextants, and presents numerical comparisons with similar data from metal sextants.

No previous navigation experience is required. The only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it book, which also includes clear explanations of how it works and how to do it well. Plus this book includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, and more.

We are pleased to say that after ten more years of using this text we do not find reason to change the basic approach and methods of the teaching. We still use most of the same examples, which are now quite old, but that is the beauty of celestial navigation. It has not changed, so we do not benefit in any way from making all new examples, which would bring with them more chance of error in a book of many numbers. We have, however, notably improved and expanded the book. Each section has been updated and reformatted for a clearer presentation, often in response to student questions over the years. New graphics have been added and older ones all updated. There is much new content in the text, especially in the In-Depth chapter, including more detailed discussion of the sailings and more background on the principles. New sections were added on general ocean navigation and optimizing the fixes.

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, FRIN \u003c\/span\u003e\u003cdiv class=\"pc-book-specs\"\u003e\n\u003ch4\u003eBook Details\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePages:\u003c\/strong\u003e 315 pages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 8.5 x 11 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Paperback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublisher\/Distributor:\u003c\/strong\u003e Starpath\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISBN:\u003c\/strong\u003e 9780914025214\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Starpath","offers":[{"title":"Default Title","offer_id":67857219780853,"sku":"STR020","price":39.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0829\/2198\/0149\/files\/STR020_104lb.jpg?v=1794315004"},{"product_id":"celestial-navigation-3rd-edition","title":"Celestial Navigation, 3rd edition - Book","description":"\u003cspan style=\"color: #808080;\"\u003eAs romantic sounding as sailing to Tahiti did centuries ago, using the sun, moon, planets, and stars to guide one's boat on the seas is enjoying a comeback.
