    Dear Frank,

    Let us better compare with ordinary Lunars.
    It is less accurate than the ordinarey Lunars by a factor
    of two, if the Moon is near zenith.
    And by a factor of 4 if the Moon's alt is 30 degrees.

    Yes, this is what I mean by b).

    So far I cannot.
    I hope we will clarify the reasons after you test
    my sextant, and I test my observation skills/abilities
    with your sextant.
