Explore Scientific 8x50 Erect Image Illuminated Viewfinder, Wide 6° Field of View
The illuminated reticle of the 8x50 Viewfinder with its scale markings and open center not only helps you center objects precisely, but gives a reference of the exact field of view in degrees. The deep red illumination is continuously variable to provide the desired brightness. The Explore Scientific 8 x 50 produces a wide 6 field of view and allows precision focus of both main objective and eyepiece illuminated reticle. 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 cross hairs) and scale markings for 1.5, 3, and 4.5 (the edge of the field of view is the 6 boundary). All Explore Scientific telescope accessories are covered under the standard U.S.A. One Year Limited Warranty against defects with proof of purchase, but you can extend this limited warranty to five years by simply filling out the product registration and submit it to Explore Scientific within 60 days. This program is also available to the person who receives your gift of an Explore Scientific telescope. You don't need to give them the purchase receipt, just remind them to fill out the registration and submit it to Explore Scientific and they will take care of the rest.
