The premium four element optical set is finished with multiple layers of high transmission coatings for clear, sharp images. The edges of the optics are blackened for increased contrast. The Omni eyepiece body is made of aluminum.
A two step anodizing process results in a beautiful matte finish that resists reflections and glare. Each eyepiece in the Omni Series includes a black rubber eyecup. It can be left up or folded down for better observations while wearing eyeglasses.
Models with a longer barrel (15 mm, 32 mm, 40 mm) include a rubberized grip for non slip handling during observing sessions. The insert barrel is threaded to accept 1.25 inch filters. The eye relief for this 4mm model is 6mm.
