Modern Celestial Navigation

Winter / Spring 2026:
  • Register Jan 31,Feb 1 ATLANTIC session: 10am-4pm US Eastern time (1500-2100 UT), online.
  • Register Apr 6,7,8 PACIFIC session: 8pm-11:45pm US Eastern time (0100-0445 UT next calendar day), online.

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 workshop

Created 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.

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.

If we could leave 5 stars, we'd leave 10 ! We have attended several courses and enjoyed each one! Mr. Frank Reed is as entertaining as is his complete mastery of the subjects he teaches. The level of preparedness shines like the stars he so loves. We thank you for the most excellent courses we have had the ultimate pleasure to experience.

I just took one of Franks classes and it was awesome!!

Frank taught an incredible class on celestial navigation that brought me from novice to some solid understanding of sextants, their history and most importantly their use as a aid to seeing the sea...and knowing where you are on this planet!

Hands on, wealth of knowledge, great resources ... he really covered a lot of ground! There was a lot of math but unlike in my youth, I was on the edge of my seat to soak up knowledge!! Frank made it relatable and real. The sextant which is such an iconic tool of the sea, was demystified. By the end of class i felt comfortable with it. I had mastered how it worked, how to read it and how to adjust it to insure its accuracy.

I came away with all of the cheat sheets and understandings of equations and concepts that breathe the life into what you capture through your sextant sightings.

I would highly recommend Frank and believe Mystic Seaport with its planetarium, an ideal setting for my class with him discovering this timeless tool of the sea.

Frank did a great job keeping the class interesting with visual aids, both on screen and out on the Seaport grounds.

All in all i would highly recommend this class to any and all folks interested in learning about navigation and sextants. Informative and digestible, but most of all useful to the point where i am comfortable with the instrument and have the formulas needed to continuing to set my sights on the horizon!!

I look forward to more classes to learn more from Frank and strengthen my understandings of celestial navigation!

Thank you!!!

Lunar Distance and Age of Sail Classes:
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.
