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

    "...what does “Near” or “Far” signify in the window next to distance?" -Paul

    That refers to whether the near or far side of the Moon (relative to the other body) was used in the measurement.

    If a body other than the Sun is being used, the Moon is not full, and that body is on the side of the Moon opposite the Sun, then one would need to use the "far" limb, because the near limb will not be illuminated and therefore will not be clearly visible through a sextant scope.
