    Re: Sextant Error and Whole Horizon Mirrors

    Aubrey-
    
    If you are interested, I'll send along instructions from one of the old
    manuals explaining how to adjust that inverting 'scope. I think it would be
    interesting make use of it.
    
    Just a wild guess, but I have the notion inverting 'scopes went out of
    fashion around WW I, shortly after lunar distances were dropped from the
    Almanac. Seems like those full view horizon mirrors didn't appear until the
    last half of the twentieth century. Does anyone know?
