Explore Scientific 8×50 Correct Image Finder Scope
The Explore Scientific 8×50 finderscope will show you a wide 6° field of view to help you easily find your favorite celestial objects. The finderscope enables precise focus of both main objective and eyepiece-illuminated reticle. With its scale markings and open center, the illuminated reticle of the silver 8×50 Viewfinder not only helps you center objects precisely but gives a reference of the exact field of view in degrees as well.
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 backwards like most viewfinders. The 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 degrees, 3 degrees, and 4.5 degrees (the edge of the field of view is the 6-degree boundary).
