    The Moon and bubble sextant
    From: Bruce Hamilton

    I have never shot the moon with my bubble sextants and it is the only
    body that is peeking out from the gloom tonight. It is quite handy
    actually as it peers through quite a lot of cloud and a light filter
    sharpens it up nicely. As I am sure all of you understand, I have to
    make sure that  my balcony has not changed location on the face of the
    earth.  I do not own an Air Almanac yet, and I was wondering if it
    contained correction tables for the moon and sun that were made for a
    bubble sextant. With the sun, I just use the star corrections, or
    average the upper and lower limb.
    I just got a Mark IX on e-bay for 31 dollars. It is missing the cover
    for the averaging clockwork system, and I will have to fill the bubble
    system, but it is otherwise fine. I found a reference to a page on this
    list that gives me all the details I need to remove and fill the bubble
    I now own an A-12, and A-10, and the Mark IX. Can I stop collecting now?
