    Re: Latitude by Lunar Distance

    Anyway,
    I call for the tests of the method,
    rather than the discussion of personalities
    and offenses which is going on now:-)
    
    Let us use the same criteria as were used for the Lunars
    method in XIII century. I will be surprised is the method
    permits to determine your position to 30 miles.

    By "ordinary sextant I meant of course a good one
    (but without a tripod or any other tricks which
    can work only on land:-)
    
    I should have said "well trained observer of reasonable
    ability".
    
    The arc corrections of a sextant are not very relevant
    here. A person who can measure distances to 0.1'
    reliably will have no difficulty in determining
    arc corrections of her sextant.

    I am a "big believer" in the averaging as well.

    My results are not better with your sextant.
    So it is not a micrometer problem.
    
    Alex.
