     So the questioned begged is this.  Just how much difference does a horizon 1/2 mile short of true for my height of eye actually make on an observation?
     Tis my argument that it isn't enough to even consider in practical navigation.  I don't even think you can measure it that far away.."

    I don't know, and I don't have a strong enough opinion on this to add any further, so instead, for those new to celestial navigation, I'll take the opportunity to recommend a book. The book in question has a very brief section on this topic which may or may not be right.

    Got a sextant? Get "The Sextant Handbook" by Bruce Bauer. It has all sorts of useful tips.
