DESCRIPTION

Use Vixen ED103S Refractor w/Dual Speed Focuser & Tube Rings - SOLD

The newly designed high definition ED lens on the Vixen ED103S gives excellent optical performance with 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. The new ED glass produces clear and high contrast viewing, virtually free of false color. The design on the Vixen ED103S uses newly developed, environmentally friendly glass technology, free of hazardous lead that helps to support a cleaner global environment. The optical tube comes equipped with a metal carry handle for easy one-hand carrying.

Coupled with a medium f/7.7 focal ratio, the ED series new lenses focus the full visible spectrum of visible light to a critical point much more accurately than past ED product. The ED103S 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. Vixen finishing touches include carry handle, new Dual Speed Focuser - now standard on the ED103, provides fine focus adjustments for 1/7th speed focusing - and 90mm tube rings.
