    Re: Sextant calibration accessory

    Hi Bill,

    ... Typically, the faces are about 90 x 15 mm.


    That sounds a little large to shoehorn into the sextant optical path, but maybe they could serve.
     

    I have no plans to use them to calibrate my sextants...


    Easier than the autocollimator hopscotch shown in your book, though, right?

    Cheers,
    Peter
