The ED S apochromatic refractor features Extra-Low Dispersion (ED) glass in its objective lens to suppress chromatic aberration to a virtually invisible level. Coupled with a medium f/7.7 focal ratio, the ED S series provide a sharp, color-free image of high contrast for both visual and photographic applications. For ease of target location and precise tracking, the OTA comes on Vixen's state-of-the-art SPHINX (SX) mount with computer database and visual goto. Includes SX HAL130 tripod (adjustable from 70cm to 110cm). The SX Half Pillar accessory is recommended. The SPHINX equatorial mount and STAR BOOK controller have been intelligently engineered for high-speed automatic location of celestial objects. It is now possible to explore the beauty of the night sky with greater ease and stability. The SPHINX comes standard with built in motors and the world's first star chart go-to controller, STAR BOOK, with a large full color LCD display. The SPHINX's design is exceptional and the exterior styling is equally attractive.
