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". The Vixen Telescope ED115S comes complete with 125mm tube rings and Vixen'''s New Dual Speed Focuser. Covered by a 5 Year Warranty. Manufactured in Japan.

The Vixen Sphinx SXP Equatorial Mount builds on leading edge innovations developed through decades of experience designing German Equatorial Vixen Telescope Mounts. The Vixen SPHINX SXP mount and optional STAR BOOK TEN hand controller display the best in portable GoTo technology. This new generation of hand held controllers features a high definition LCD screen and the technology to show you the sky before your Vixen Telescope takes you there.

Motors: The Vixen Sphinx SXP Equatorial Mount features pulse motors designed to react smoothly and accurately. The micro slow motion control assures you of smooth Vixen Telescope Mount operation.

R.A and DEC: The R.A. and DEC wheels have 180 teeth. They are high precision machined wheels and worm gears made of brass for the most accurate tracking possible. The R.A. and DEC shafts on the Vixen Sphinx SXP Equatorial Mount are comprised of strong carbon steel. The Vixen Telescope Mount rotational parts have 15 bearings. All this to provides smooth tracking and slewing.

Unique Mount Design: The Vixen Sphinx SXP Equatorial Mount is designed so that the Vixen Telescope Mount body acts as part of the counterweight system.

Periodic Error Correction: Data from you input is saved for your next Vixen Telescope observing session.

Polar Axis Scope: The Vixen Sphinx SXP Equatorial Mount includes a built in 6x20 polar axis scope. It features a bubble level, illuminated reticle, and Vixen Telescope Mount setting accuracy within 3 minutes.

Star Book Ten Functions: High Definition LCD Screen, Night Vision Mode, VPEC and PPEC, Built-in 270,000 Object Star Charts, Varied Tracking Rates, Object Locator, Auto Guider Port and Extension Slot for Vixen Telescope Advanced Unit

Don'''t forget... We also carry many fine Vixen Accessories including Vixen Eyepieces, and Vixen Reducers and Adapters. There'''s a complete line of Vixen Telescope Mounts and Vixen Camera Mounts, too!
