DESC: Fujinon S1240D Stabiscope is an optically stabilized binocular with 12x magnification. Unlike many other viewing devices enhanced with gyroscopic elements, not only are the Stabiscope's prisms individually counterbalanced with ± 5° of compensation, but they operate while the optics are aimed in any axis. Therefore, a user can aim the Stabiscope straight up or down, at the zenith or nadir, and still enjoy stable viewing.
