Dear Kermit,
regarding 1 and 2 "weakness", with the help of computing power, they could be avoided.
The third: Difficulty to adequately "tangent" the Moon Limb onto the visible horizon through sextants , depends greatly on the atmospheric conditions and Moon phase. Once I obtained better results with a Link A-12 aircraft bubble sextant than with two marine sextants, ASTRA and C&P. Why? Because the Moon was nearly full and the glare in the horizon made it very difficult to kiss it. also adding that there was cloudiness that made the light intensity change.
Even using a polarizing filter, I had difficulties. A very special case due to its adverse conditions.
Best regards.

The Moon. But I like it!
Best regards.
