The ASA 207 Instructor Celestial Navigation Certification course teaches the ability to determine your position at sea using timed sextant sights of the sun, moon, stars, and planets as well as other routine procedures to ensure safe and efficient offshore navigation. American Sailing Instructor Qualified Candidates must pass the proctored examination with a score of 90% or greater to receive their Celestial Navigation Instructor Credentials.

The celestial exam will focus on your ability to work with the Nautical Almanac, HO 229 and HO 249 sight reduction tables, the Star Finder (2102-D) and your ability to plot estimated positions and celestial fixes on standard plotting sheets, among other basic celestial skills.
