Astronomical observations with a reliable, error free or error corrected, sextant, quintant, or even octant can be remarkably accurate as respects the determination of Chronometer Error, even on a good sea horizon. In my personal experience, I believe the Lunar Distance to be the more difficult observation as it probably requires the greater obsevational ability, but both the Equal Altitudes and Time Sight solutions are well within the capability of the average observer and will produce satisfactory results on a good sea horizon and excellent results with a mercury artificial horizon. The proof is in the trying. Regards, Henry --- On Wed, 5/6/09, enoid@northwestel.net <enoid@northwestel.net> wrote:
