    Re: Dresden sextant - lets commission a Navlist instrument!

    Okay Paul, I'll bite.

    A repeating reflecting circle.  

    Since the index AND horizon arms can move, the angle is measured N times and the overall sum of angular measurement us divided by N.

    Example:  3 readings of 60° will yield an overall measured angle of 180°.  Divide 180° by 3, yielding 60°.  This instrument nullifies arc centering error by marching the measurement all the way around the circle.  It is graduated 0° to 720°.

    Here's an idea for Navlist. The folks who make the fake instruments in India/Pakistan are great at their craft.  Why not design a uniquely Navlist instrument and then commission one of the makers of these brass fantasies to make a small number of the instrument for Navlist folks.  Non-functional of course, but something subtly ridiculous and suitably complex that would make a fine desktop dust-catcher/conversation piece.
