    Re: Calibrating a Bris with a Davis mk15 sextant

    Alex,

    You can also attach where the scope mounts but the Bris will need to be back far enough to clear index mirror. The inventor mounted his Bris on a pair of glasses. This will work too if sextant is held out some using a sight tube (no scope).
