by taking sights on the moons of Jupiter (which are actually visible to the naked eye at sea on clear nights)

I was a navigator for the USAF/ANG — did a lot of tricks with a sextant. But never saw the moons of Jupiter without a telescope and never heard of any navigation tricks using the moons of Jupiter.

Now listen Owen, most USAF people use the FTC navigation method (Followe The Colonel) and are always looking through dirty plexiglass, so no, I don't guess you could see the Moons of Jupiter.

But they are plain as day on a clear night. BTW, in my day lots of USAF people seemed to be lost, so I must take the word of a USAF Navigator cum grano salis, economy size.
