    Re: Lunar distance measurement in ideal conditions: attainable accuracy.

    Bill,

    If this is the case, then Cook's error in his Lunar observation
    is large indeed.
    Then you are right that sea observations are much less accurate than
    land observations from a stationary observatory.
    
    Which is not surprising of course.
    In my own experience sometimes I was able to shoot excellent Lunars
    from a yacht (in a very calm weather), but in general my experience in
    shooting from a yacht is very small, and when there are substantial
    waves, this seems really difficult.
    
    
    Alex.
