Technical Specs

When The ED81S Refractor was introduced, it set a new standard for APO Refractors. 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 new Super Low Dispersion (SD) glass produces clear and high contrast viewing, virtually free of false color. Vixen's innovative design uses newly developed, environmentally friendly glass technology. SD lenses focus all visible rays of light at nearly the very same position. This ensures that the chromatic aberration is highly corrected over a wide spectrum of light. Of special note is stray light, which affects image contrast, is well suppressed. The optical tube is very stable yet light weight. Vixen's new Dual Speed Focus, now standard on the ED81 Refractor, provides fine focus adjustments for 1/7th speed focusing. The Japanese made ED81S is covered by Vixen's 5 year warranty. Instruction Manual here.
