    Hi Bill
    Consider buying the HO2102D Star Finder/Identifier...Several stores in Vcr
    sell them.

    Subject: [NavList 5946] Star Identification
    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.
    Thank You
