    Zvi,
    
    > You sure have been busy, mate...
    
    Not really:-) All that I desctibed happened in 7 years.
    This is only one of my hobbies, and I still have a full time job
    besides the hobbies.
    
    Of course, I am not a sailor. And most of the observations I made
    are from my comfortable balcony, and they are Lunars, star distances,
    art horizon observations etc.
    
    For example, the statement that "one prefers a bronze frame when the wind
    is strong" is pure theory to me. SNO-T has a big cut in the handle, I
    don't
    know what for. One can put a piece of lead in it, and it will weight the
    same as the biggest bronze frame sextant:-)
    
    On my opinion, bronze frames are preferred for sentimental reasons.
    (I also thought in the beginning that a bronze frame of Cassens-Plath
    and Tamaya looks like a "real thing", while aluminium frame is a
    "cheap substitute". Actually, I have a very old booklet by Hezzanith
    which clearly states that aluminium alloy frames are MECHANICALLY
    SUPERIOR, more rigid, and they cite numbers. But conservative seamen
    still prefer bronze frames... Bill Morris says exactly the same, based
    on his tests of frames.
    
    Now, I am convinced that SNO-T Kepler telescope is by far superior
    to the "standard" modern Galileo sextant telescope in all conditions
    that I tested. My SNO-T is equipped with both, but I also tested
    Astra and other telescopes. (In a
    small boat it is better to observe without any
    telescope if there is any rolling).
    
    SNO-T standard Kepler 6x is comparable to a prizmatic 8x30,
    but has larger field of view and a small fraction of its weight and bulk.
    
    Alex.
