Modern Celestial Navigation
A fast-paced introduction to celestial navigation from a 21st century perspective employing streamlined, practical, modern methods.
We cover Sun sights in detail, correcting sights for dip, refraction, and other details to determine a "position fix" in latitude and longitude. We'll use efficient, modern Sun data from the "guidebook" which you will receive as part of this workshop. We'll learn about the diurnal motions of the Sun and stars in different latitudes and seasons.
With everything you learn in this class and complete tables you will receive in class, you could navigate the oceans by sextant the very next day. This workshop covers the principle, use, and adjustment of modern sextants. You'll learn how to calibrate any sextant in just a few minutes to bring it to perfect working order.
Advanced Celestial: Position Fixes & Star Sights is recommended as a follow-up.
All workshops: $ 149 per person, per workshopCreated and taught by Frank Reed, celestial navigation and astronomy consultant on the team that found Shackleton's "Endurance" in 2022. Also a recent guest expert in celestial navigation on Neil deGrasse Tyson's StarTalk on The National Geographic Channel.
- Nine hours of class sessions.
- Before this workshop: no pre-requisites; designed for beginners.
- Some math you'll need: Basic addition and subtraction; good familiarity with the concepts of latitude and longitude; introductory algebra concepts, especially positive and negative numbers.
- Recommended for ages 18 and up, students as young as age 13 welcome.
- You'll need to purchase the recommended scientific calculator for the class: the Casio fx-260 Solar (original or newer "II" model). These are widely available for less than $15 at Walmart, Staples, and other stores.
If you're registered for an online workshop, you're invited to attend hour-long sextant practical sessions in Rhode Island and Connecticut scheduled as weather and other factors permit. These live, in-person sessions are included in your registration for online classes.
Comments:
Fascinating classes taught by a fascinating and capable instructor.
Lunars class is challenging and fun. Frank presents several different recipes for accomplishing lunars, one of which seems almost easy (kind of). Highly recommended for anyone interested in celestial navigation or nautical navigation history.

I must admit I dreaded two, back-to-back, 5-hour days, but the time sailed by. (Sorry can't resist.) Thank you.
He also included some 17th century data that I needed. I'm neither a mathematician nor a sailer, but a journalist and author.
