Vixen ED100Sf 100mm ED Apochromatic Refractor with Sphinx


The ED 100Sf is now available with Vixen's Dual Speed Focuser. Vixen's apochromatic refractor has an extra-low dispersion (ED) lens which depresses residual aberration to ahcieve a high level of performance. Coupled with a medium f/9.0 focal ratio, the ED "S" series provides sharp, high contrast color-free images. For the astronomer that wants the best value for the dollar in a 4” APO, this is the one to get.

PLUS: While the outsides might look similar to the standard Sphinx Mount, the changes that have happened under the hood are huge! Incorporating one piece hardened steel RA and DEC shafts with needle bearings throughout, the new Sphinx D can handle a load capacity up to 50 lbs. The Sphinx D comes complete with PEC, backlash compensation, and the incredibly accurate SX Polar Finder Scope.

Astronomers with larger optical tubes and all level of astrophotographers are sure to feel right at home with the intuitive controls that so many have become accustomed to with the standard Sphinx Mount. Its 4.7" Color LCD Display gives an exact position against its scrolling star chart, any object is a point and look away!

  • Built In Bearings: RA and DEC axis bearings reduce the load on the motors and ensure smooth tracking
  • Precision Worm Gears: Manufactured with high precision, they deliver smooth movement throughout the full circle of the worm screw and gears.


The innovative STAR BOOK hand controller offers astronomical navigation with a large full-color LCD screen! The color screen is a detailed star chart that acts as a navigational and GOTO guide for the mount. The database contains over 22,000 objects and others can be added. Zoom-In/Out buttons for the color star chart display also control the motor speed. As you zoom in closer to an object on the display screen, the motor speed automatically becomes finer and as you zoom out the motor speed increases to cover larger distances.
