    Re: Bris Sextant

    This also would explain another "deficiency" the 8 images if Sun
    that I see are not aligned on one vertical line.
    However I don't see how it could affect precision, and don't think it
    On my opinion, the only limitation of precision is the absence of
    the scope. If one attaches the scope, the attachment should certainly
    have a collimation adjustmeent (rotating the Bris part around a vertical
    axis). With such adjustment, I do not see why Bris device will be less
    precise than ordinary sextant.
    (Of course I do not mention again its other limitations).
    Alex, I've followed this thread from the start. Glad you got one of these
    Bris "sextants" as they are a great and a unique tool. I found mine in a
    chandler's shop in San Pedro, Ca. a few years ago and have used it many
    times. I carry mine in an old aluminum film canister when not in use. I also
    took a pair of glasses, popped the lens out and attached a wire clip
    arrangement to hold the Bris to the frames while useing.
