    Re: Bris does not work

    Greg,
    Thanks for your advise: a little cleaning of inner surfaces
    indeed restored all 8 images:-)
    I suspect that the following happened.
    On my trip to Helgoland, I put my Bris on a rope as a pendant on my neck,
    under the shirt. The weather was very hot, and the glass could be
    fogged by the sweat:-)
    
    Cleaning the inner surfaces is difficult: I used a needle and
    a piece of fine silk to wipe it from inside. Still I could not reach
    the sharp corner.
    
    The pattern of the images on my Bris is different from yours:
    b,b, d,b,d,  d,d,   d,
    where b and d stand for "bright" and "dim", and the number of spaces
    approximately reflects the pattern.
    Actual altitudes (for the center of the Sun) are approximately
    10,13,  21,24,26, 34,36, 47 degrees.
    
    Alex.
