    Re: Full moon sights and lifeboat sextant accuracy

    Taking a night/twilight sight of a full or largely illuminated moon is not recommended because the illumination of the water by the moonlight almost always makes a false horizon appear below the moon.

    Subject: [NavList] Full moon sights and lifeboat sextant accuracy

    I was doing sights of the sun and moon on a dock yesterday, using a Davis Mk3 "lifeboat" sextant and was about 26 miles off as compared to GPS. So I was curious, for people who have used that sextant before, what kind of accuracies were you able to obtain?
    Also, I vaguely remember reading somewhere that taking sights of a full moon (as opposed to a crescent moon) was not recommended as it for some reason decreased accuracy. I can't seem to find a reference anywhere to this, does anyone know if this is true, and why?
