Intermediate Celestial Navigation: Star Sights and Lines of Position

This is an excellent sequel to our Easy Introductory Celestial Navigation class. In this course, students will learn more about the use of the sextant and will learn the traditional “twilight round” of star sights for determining a vessel’s position by plotting lines of position and working with “H.O. 249″ sight reduction tables. Students will also learn traditional shortcuts for locating the brighter navigational stars under the dome of the Treworgy Planetarium. Students will be provided with the necessary plotting tools and digital copies of the sight reduction tables.

Requirements: an introductory course or equivalent in the use of a sextant and other basic techniques in celestial navigation.

Instructor: Frank Reed of Reed Navigation
