Tony:

Thanks for your latest input, especially as I assume that you have other things to do, that require your attention.

In any event, the following might possibly be enlightening, or amusing. My efforts at "celestial navigation" are likely about as far from actual CN as one can get,amounting to position verification. Essentially, what it all amounts to is seeing how close to a known position, GPS coordinates, my calculated position is. This derived from shooting the sun twice a day, with 4 hours separation, going through the grubby arithematic to reduce and plot the sights. My calculated position usually comes out within, sometimes well within 5 miles of GPS position. Now and then, both the sun and moon are shootable during the daytime, they will be so next week I believe, allowing for a two body fix. Have never had much success shooting stars, though one time, quite a while back, I got a 3 body  fix, shooting the Moon, Jupiter and Venus. The triangle formed was very small, indicating either the fates smiling on my efforts, or that I knew, or had learned a bit about what was what, likely the former. Living inland, Pittsburgh, PA., I'm usually reduced to the use of an artificial horizon, shooting the sun from a convenient parking area. It is possible to get shots across the Monongehila river, dip short method is used, which sometimes works, but nothing like looking out to sea, with a real horizon.

If you have gotten this far, thanks again for your input.
