    Re: Determining tangency for moon & sun sights

    Randall asked:

    Is the quality of the optics a factor in seeing the point of tangency?

    Can't prove it, but I suspect that the answer would be YES!!!
    Additionally, I also suspect that the quality of the mirror in your AH is also a factor.

    Also, while the Davis Sextant is certainly useable, metal frame sextants are a lot more expensive, the Davis isn't the most reliable of instruments.
