Discover intricate details of the Moon’s cratered surface, trace the elegant structure of Saturn’s rings, and explore the brightest deep sky objects in stunning clarity with the Explore Scientific ED127 FCD100 Carbon Fiber Triplet APO Refractor.
This model combines the proven design of the original EDT-127075-CF with an optical upgrade: HOYA FCD100 ED glass, renowned for its exceptional chromatic correction and optical characteristics comparable to Ohara’s FPL-53. Paired with high-index glass elements in an air-spaced triplet configuration, this telescope delivers crisp, color-pure, diffraction-limited performance across a wide range of targets.
All optical surfaces are coated with Explore Scientific’s proprietary EMD multi-layer coatings, improving light transmission and contrast for both visual observing and imaging.
Built into a lightweight carbon fiber tube, the ED127 is designed for users who value stability, portability, and thermal control—qualities that benefit both field work and astrophotography. At the back end, it’s equipped with a 2.5" HEX focuser, a precision-machined component that supports up to 10 lbs of gear, providing rock-solid focusing for even demanding imaging setups.
