Explore Scientific 8x50 Illuminated Erect Image Silver Finder Scope

8x50 Illuminated Erect Image Silver Finder Scope The Explore Scientific 8x50 produces a wide 6° field of view and allows precision focus of both main objective and eyepiece illuminated reticle. This finder now includes the NEW long battery life Illuminator II. A precision polished roof prism produces images that are right-side-up, left-to-right correct. In other words, things are not upside-down and backward like most viewfinders. This illuminated reticle is truly designed for finding objects with its open center (so you don't mask the object you are centering with crosshairs) and scale markings for 1.5°, 3°, and 4.5° (the edge of the field of view is the 6° boundary). The 55° apparent field, 16mm long eye-relief eyepiece produces a bright 7mm exit pupil and will allow you to find faint galaxies, comets, and nebulae. All optics are EMD Coated to ensure maximum contrast. The illuminated reticle of the 8x50 Viewfinder with its scale markings and open center not only helps you center obje
