"AFAIK, the US Navy still uses Bowditch."
And they'd damn well better, because they (NOAA, DMA, GSIA, whoever it is this week) still maintain and publish the damned thing. And of course it goes well beyond simple celestial nav.

"I seem to recall hearing that they recently stopped teaching celestial navigation at Annapolis." IIRC at least five years ago it changed from mandatory to optional?

Of course when laser-ring gyroscopes ramped down from a quarter million to a mere fifty cent integrated part, I'm sure that changed the whole field of inertial navigation systems as well.

There are a lot of nay-sayers out there on the subject, about how useless it is in this "modern world" of ours. But what if you were out on an ocean passage and the ultra reliable government(s) shut the GPS signal off. Or what if the Myans just happen to be right and things crash down (or up) around us and a few are left to re-discover what is left. How will they get around without a signal to lock on to with their useless techno gadgets?

I say good for you Chris. I am going to use the Starpath program; looks very good and has a lot of positive feedback.
I think you got it right in your first sentence. It is an art, to be done for the reason anyone pursues an 'art' for a sense of achievement and self satisfaction. It was for these reasons I pursued it.

While I wouldn't go as far as to say it is useless, I do think the argument for it being a necessary skill for offshore sailing has now passed.

If Mayan end of world prophecy proves true, or if the US government reaches a point where it's military systems are rendered inoperable I am not sure I personally would ever want to find shore again

I loved "Celestial Navigation in a Nutshell" by Hewitt Schlereth.

Clear, practical, a little history, entertaining. Easy read.

Gotta love this stuff.

CN is alive and well! I use it every time I sail to confirm that I am in the vicinity of Lake Arthur in western Pa. Haven't been wrong yet! ;-)
