• One of the characteristics of Dobsonian and Newtonian telescope designs 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 the highest quality ABS-grade polymers for maximum durability, ease of care and appearance.
• Heavy duty straps  with Velcro® brand fasteners.
