    Greg,
    Your method is the easiest but I haven't a sextant. I'm in theory now.
    Thanks a lot.

    Fran,

    What I do to save time on Bris calibration is to use a metal sextant as the standard.  Mount the Bris six inches behind a sextant sight tube then it is just a matter of overlapping Suns and reading off the sextant for the calibrated angle (good to about +/- 2 '). A lot quicker than waiting all day for the various Suns to set on a natural horizon.
