Doug,
One thing interesting about physics and other sciences is that one can
figure out what's going on in some areas without having to delve into
the specialized knowledge of people in an industry, which oftentimes is
closely held. Or at least one can figure things out _if_ one can apply
the principles correctly! For me, it is absolutely wonderful to see
George Huxtable doing just that. Being basically a farmer, I often
have to figure such things out on my own or with my co-workers, so I
find it a useful skill.
Regarding sextant calibration, I know of several shops in the U.S. that
will align the telescope parallel to the axes of a sextant, but none
that can give the error corrections at various angles that are
displayed on the correction certificate inside the lid. If you know of
any, I would be delighted to hear of them.
Thanks,
Fred
