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 mechanism. I now own an A-12, and A-10, and the Mark IX. Can I stop collecting now?
