Re: Celestial Navigation

Not since Myan 2012. The end of the world stuff was a total crock of codswallop but they were correct in saying the axis of the earth is moving at about .5 degree per year, so now its 2.5 years later you will always be miles out in your LP.

Its clearly shown in the graphic attached.

Re: Celestial Navigation

i would think the nautical almanac which you get each year corrects for this, so your fixes are still ok.

Yes, through corrections to precession and nutation found in HO-249 Vol. 1
TABLE 5 CORRECTION FOR PRECESSION AND NUTATION.

Re: Celestial Navigation

I have a couple of cheap sextants, and I've learned to use them well enough that (if need be) I could probably manage to find my way to Hawaii or some other fairly large target. It's kind of fun, and a bit frustrating at times.

But, let's face it, CN is a bit like being able to paint a pretty picture. I could invest in oils, canvas, brushes, an easel, etc., and sit down for hours and paint away. It would be fun, and probably a bit frustrating. In the end (and after a lot of practice) I would probably be able to paint something that looked pretty much like the subject at hand. OR, I could whip out my iPhone, take a digital pic, and have something that looked exactly like the subject.

Re: Celestial Navigation

Noon shots are fun. Particularly if you have an app or program that converts the data to position. Just like sailing itself, showing a newbie how its done is like revealing how the wizard does their magic. It's just not as hard as some think. Triangulating the constellations, that's not fun.

Beer and pretty women. Also fun.

Re: Celestial Navigation

Usually, on board I have a certain amount of time to spare and find CelNav very enjoyable and easy. Minimization of electronics is important to me. Dead batteries and I go hand in hand.

You can get The Nautical Almanac for free at- TheNauticalAlmanac.com

The site offers the Almanac up to the year 2020 plus a lot of other CelNav info.
