    > Hi As a yachtsman new to astro nav, I acquired a Kelvin Hughes sextant 
    serial no 50117, it's grey ex admiralty. In the box is a fairly large dia 
    lens which is the one I use as well as a telescopic eyepiece with 2 
    changeable lenses one has a pair of parallel lines the other 2 pairs of lines 
    at 90 degrees. These invert the image. What are they used for. Also I have 2 
    shaded what appear to be replacement lenses not screwed and don't appear to 
    fit anywhere. Can anyone explain the purpose of these please  . Thanks Jerry
