Vixen ED103S Refractor Optical Tube Assembly (OTA)

The newly designed high definition ED lens in Vixen's ED103S Refractor gives excellent optical performance in a short optical tube for easy handling. The new ED lenses feature brighter images from the shorter f/7.7 focal ratio and capture crisp, pinpoint star images for your eye’s enjoyment. Vixen's ED glass produces clear and high contrast viewing, virtually free of false color. The design uses environmentally friendly glass technology, free of hazardous lead that helps to support a cleaner global environment.

Vixen's new lenses focus the full visible spectrum of visible light to a critical point much more accurately than past ED products. The ED103S Refractor's lenses are almost free of chromatic aberration in all colors and are critically sharp edge to edge. The astro-photographer will be especially pleased with the high contrast images through this telescope. The ED103S Refractor comes complete with 90mm tube rings, compression ring, and Vixen Dual Speed Focuser. Manufactured in Japan; Dimensions: 115mm x 800mm/ 4.5 x 31.5 in; Weight: 3.6kg/ 7.9 lbs
