About the Vixen ED115S - 115mm Refractor Telescope w/ Sphinx SXP Mount & Starbook Ten...
The newly designed high definition Vixen Telescope ED lens on the Vixen ED115S Refractor Telescope gives excellent optical performance with its Extra Low Dispersion (ED) glass. Chromatic aberration is virtually eliminated. The Sky at Night Magazine states: "Vixen'''s optics were excellent. The scope corrected false colours almost perfectly when in focus...Pointing the Vixen Telescope at the stars showed the optics to be pretty much perfectly corrected".
The new ED lenses incorporated into the Vixen ED115S - 115mm Refractor Telescope feature brighter images from the shorter f/7.7 focal ratio to capture crisp, pinpoint star images for your enjoyment. The Vixen Telescope ED115S Refractor'''s lenses are made with environmently friendly technologies, free of hazardous lead that helps to support a cleaner global environment.
The astro-photographer will be especially pleased with the high contrast images through the Vixen ED115S - 115mm Refractor Telescope and the full objective diameter of 4".
