BSA CATEYE3-10x44IRw/ILL RTCL Scope BSA CATEYE3-10x44IRw/ILL RTCL ScopeBSA made the catseye as bright as they possibly could. They started with extra large objective lenses to gather in as much light as possible. Camera quality glass was used to give a clear, undistorted, flat image. The objective and ocular lenses were fully coated to provide the brightest view without glare and reflections.
