Includes techniques for checking compass and sextants. \u003c\/span\u003e\n\u003cp\u003eJeff 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.\u003c\/p\u003e\u003cp\u003eFrom 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.\u003c\/p\u003e\n\u003cdiv class=\"pc-book-specs\"\u003e\n\u003ch4\u003eBook Details\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthor:\u003c\/strong\u003e Jeff Toghill\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePages:\u003c\/strong\u003e 110 pages\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 5.5 x 8.5 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 WW Norton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISBN:\u003c\/strong\u003e 9780393302943\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"WW Norton","offers":[{"title":"Default Title","offer_id":67857338040565,"sku":"WWN128","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0829\/2198\/0149\/files\/WWN128_104.jpg?v=1793863507","url":"https:\/\/uhahm3-rm.myshopify.com\/products\/celestial-navigation-5356","provider":"Paradise Cay Publications, Inc.","version":"1.0","type":"link"}
