The high definition ED lens on Vixen's ED115S Refractor gives excellent optical performance with its Super Extra Low Dispersion (SD) glass. Chromatic aberration is virtually eliminated. The Sky at Night Magazine states: "Vixen's optics were excellent. The scope corrected false colors almost perfectly when in focus...Pointing the scope at the stars showed the optics to be pretty much perfectly corrected".
The SD lenses on the Vixen ED115S feature brighter images from the shorter f/7.7 focal ratio to capture crisp, pinpoint star images for your enjoyment. The ED115S Refractor's lenses are made with environmentally friendly technologies, free of hazardous lead that helps to support a cleaner global environment. The astro-photographer will be especially pleased with the 4.5” diameter and the high contrast images. The 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. It is of special note that the g-ray light, which affects image contrast, is well suppressed. The ED115S comes complete with 125mm tube rings and Vixen's Dual Speed Focuser.
