    Alex,

    Are you familiar with the Bris type sextant ? A simple version of one of these made from two microscope slides will raise the body above the horizon enough to clear any clouds. Knowledge of the angle is not needed as long as the same device is used to time the horizon set for the Sun and Moon.
