One of the characteristics of the Newtonian telescope design is the location of the eyepiece near the open end of the optical tube. Frequently, stray light travels over the opposite side of the optical tube and prevents optimal viewing. Astrozap's Light Shields block stray light from interfering with dark adaption and concentration, thereby enabling a more enjoyable observing experience. Astrozap Light Shields are proudly made in the USA of ABS plastic for maximum durability, ease of care and appearance.
