George,
IMHO, the question should not be whether a camera can replace a
sextant one to one, but rather what can be done with a camera, and
only then you may eventually find what this can be useful to.

Please see:
http://planetarium.unr.nevada.edu/About_Us.html
where it says:
"A 30-ft. diameter, 60-seat theater with both a state-of-the-art digital star projector and a large-format (70mm) film projector"
I wonder whether a lens/optical system similar to those used in these types of projectors could be useful for such purposes.
Now this would require a specialized gadget rather than a commonly available camera, but it's a thought.
