    Re: Navy MK 5 Octant Using Natural Horizon

    Dear Greg,
    Thanks for the data. I reduced the results and obtained the same errors.
    One more question: you preset the octant.
    Why did you preset on such random altitudes without any apparent pattern?
    How did you decide on which altitude to preset?
    I repeat that the results look extraordinary to me.
    I mean I have never seen anything like that.

    Where does this number 0.2' come from? From the average of
    your whole series?
    I regrett that my bubble octant does not have this feature
    of observing with the real horizon:-)
    What is the telescope power btw?
