I just received an A-10 that I got for cheap on E-bay. Well, most of one as is is missing the averaging mechanism, but as I plan to use it with my feet firmly planted on the ground, I don't need that bit. I also managed to coax a bubble out of it too. I must say that it is the best thing for us urban dwellers with no horizon handy. I might get a calibrated A-12 next as I love the concept. Put the body in the center of the bubble and I have a reading. Very nice! I am a bubble sextant fan now. I have one question for someone who has used one (A-10) before. What is the use of the frosted glass that swings over the top of the bubble column? Mine has some faint lines on it, but it seems to me that if the body is in the bubble, no other reference is needed. As well, it seems to me if I peek to the left of the view, I could see a natural horizon, if I had one. Is this possible or a pipe dream? Another question. Last night, I could get a reading from a single star through a single whole in the clouds. My star identification skills are still poor, and those circumstances were beyond me. Is there a quick and dirty way to take that single observation and find what star I was looking at using the observation, an Almanac a watch and calculator? I think I found the star in the site plan section of Celest Nav on my palm pilot, but I would like to be able to do it without.
