    And an extreme case is the so-called "Bris sextant" which is a fascinating
    device, of course, but definitely a shift in the meaning of the word --it
    has no arc at all and no limiting range. These days, I think anything that
    can accurately measure angles between celestial objects (or between a
    celestial object and the horizon) will be called a sextant.

    PS: for anyone in the group who hasn't heard of the Bris sextant, you may
    want to searc the list archive here: www.fer3.com/arc. It's a neat
    pseudo-sextant, and you can make one at home.
