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?
