  • Description

    The Vixen ED81S II is the SD Glass Scope that travels with you. This ED refractor features fully multi-coated ”Super Low Dispersion Glass" in the objective lens. The SD Glass in Vixen's ED81S Refractor Telescope suppresses residual chromatic aberration far under the threshold of visibility, producing sharp, high contrast images. The combination of better color correction from the new SD glass and brighter images from its fast f/7.7 focal ratio will satisfy the most demanding visual astronomer or astro-photographer.

    The ED glass for the Vixen ED81S II uses newly developed, environmentally friendly glass technology. The optical tube is very stable yet light weight. Vixen's new Dual Speed Focuser, now standard on the ED81 Refractor Telescope, provides fine focus adjustments for 1/7th speed focusing.
