Btw, for those interested.
Back in November we got up at 1 a. m. while doing our 1820’s survey gig at San Felipe SHS and did a star shot off polaris to determine the current declination. With our 18th century equipment,next morning when we could shoot the angle, we arrived at a magnetic declination of 2 degrees, 45 minutes east. We did not know the true declination before hand.
When the professional surveyor arrived we informed him of our results. He whips out his trusty iPhone and says well lets see what my app says is the current declination here today, he gasp and asked again whatwe got. We told him. Come to find out the current declination was 2 degrees 48 minutes east!!!!!

Yes. They aren’t difficult to use, but you’ll need a very accurate watch if precision is your goal. And a book that correlates celestial elevation with longitude. It’s easier if the sea state is not mountainous. 😁
I am..........disturbed.

I kinda figure if anyone knows, it would be KW. I not sure, but I think he was Columbus's navigator. Randy, they most likely had an astrolabe.

These are my opinions, feel free to disagree.

I believe that is what Lewis & Clarke used to map the westward trip that they took.
Many of the points that they established have been checked with modern methods and found to be right on or very close.

I'd love to have one. Back in the day, moons around Jupiter were used to fix local time. Without time, you don't know where you are. "Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time" was a good read.
It took him 30 years to get his gizmo right for navigation but when he got it done, the whole civilized world was in his debt. It then led to tonight's NYC Times Square ball drop.

Yeah, even have one - a beautiful Weems & Plath. Took a class in the late 80's when I had dreams of taking my sailboat on a circumnavigation but never got any good at it. I found I was much better at reading lat and long's off my Loran's screen & later, the GPS. Got lazy, which is a bad thing when it comes to navigation. Currently have a chartplotter at the helm of my sailboat ... practical but not real elegant.

That tool sailors use to know where they are? Airplanes used them too. Just sayin... Back in the day, 1989ish when on active duty I “shot cell” (celestial) in the B-52 using a sextant to navigate across the pond before the days of GPS. A radar scope, chart, stopwatch and cell was a blast to get from point A to point B. A third of navigator training at the time was on celestial navigation, times have certainly changed …

We did the same on the KC/EC-135s in the seventies. My EC-135 at Moldyhole was scheduled to go to Tinker for PDM work. On the flight across to CONUS the J-4 compass was off a RCH, same for the sextant. They hit their entry point into Canadian airspace off by sixty miles, Canada wasn't impressed. To add insult to injury it was our instructor navigator onboard. I was with the crew that flew to the U.S. to pick up the airplane and bring it back to Moldyhole, made sure the Nav brought a good sextant with him.

A good friend had about 6 of them, and agreed to teach me.
Shortly after, his house burned down with almost everything in it. On his birthday. Jan 12, IIRC.
Wish I could have learned.
