    Re: On lunars generally
    From: Geoffrey Kolbe

    Hello Frank
    
    You wrote (in NavList 8991) "Lunars were no longer used much after
    1850, and that's because chronometers had become cheap and reliable.
    It was easier to buy two chronometers than to pay for the
    high-quality sextant required for lunar observations."
    
    So... do you mean that a marine chronometer was half the price of a
    good sextant in 1850? Gosh!
    
    What was the price of marine chronometers and good sextants in the US in 1850?
    
    Thanks
    
    Geoffrey
