    I haven't been able to do much better than that, except under
    exceptionally smooth conditions. I am talking about boats in the 30-36
    foot range. I have never tried a scope of greater than 3X, but I doubt
    that it would help on boats that size.
    
    I have a 1957 Kelvin-Hughes sextant. Other observations with a Davis Mk
    10 have not been much worse, as long as I redid the index error between
    shots to allow for the plastic moving with temperature.
