Abstract
Abstract An optical stabilizing device incorporating a relay optical system of substantially unit magnification which is inertially stabilized and adapted to relay an image from the objective lens focal surface a distance of one focal length of the objective lens which is insensitive to pivot-point mounting, and other than unity magnification which is stabilized by selected pivot-point mountings.
