    Hi Paul,

    <<  had a +/- 20o or so range of motion, whereas the sextant had to work from 0o – 90o .  So my proposed solution was to mount a bunch of them , each offset by, say,  15o  >>

    Interesting idea.  As you said the software could easily figure out which one to use.  These might be available as an array in an IC chip, with a temp indicator to make adjustments, or it would be easy to arrange 6 or 8 on a circuit board.  Then you could slap this on the side of a scope and point it straight at the body.  Maybe it could be mounted in a toy gun with a scope to shoot stars and scare pirates.

    I noticed the link posted today about the scope on a USB cable; I wonder how that's workin' out.  I'll check on it.
