Explore Scientific 8x50 Straight Through Illuminated Viewfinder with Bracket and NEW long battery life Illuminator II

The Explore Scientific 8x50 Straight Through Illuminated Viewfinder is a finderscope built for astronomers who need to precisely locate faint deep-sky targets from a telescope's mount. It now ships with the new long battery life Illuminator II for extended sessions under dark skies.

• 6° Field of View with Illuminated Reticle: An open-center reticle with 1.5°, 3°, and 4.5° scale markings avoids masking the object you're centering, with continuously variable deep red illumination.
• Right-Side-Up, Correct-Left-to-Right Image: A precision-polished roof prism produces a normal, non-inverted view unlike most finderscopes.
• 55° Apparent Field, 16mm Eye Relief: Produces a bright 7mm exit pupil suited to locating faint galaxies, comets, and nebulae.
• EMD-Coated Optics: All optical surfaces are coated for maximum contrast, and the new Illuminator II runs on two AAA batteries (not included).
