    Re: Bris Sextant Solar Filter

    John,

    See image of my homemade microscope bris showing images 5,6,7,8 through a 52mm polarizer and UV camera filter. Shows dimmer than sun reflections off the water. Hasn't been a problem for me. Just dont look directly at the Sun through it.

    The series of reflections produced by a Bris sextant reduce the intensity of the Sun, but not nearly enough to be safe for the eye. A sun-safe solar viewing filter must *always* be used when viewing the sun through a Bris mini-sextant directly. Alternatively, you can use a pinhole to project an image of the sun through  the mini-sextant onto a viewing screen.
