High-Performance Japanese Hoya Glass FCD100 Glass
Saxon's latest apochromatic triplet astrograph refractors are one to be envied. Featuring Japanese Hoya glass, the FCD100 series offers little to no chromatic aberration for almost fluorite level imaging quality, For the best of the best imaging quality for the astronomer, the FCD100 range's high refractive index coupled with propriety EMD 'enhanced multi-layer deposition' means that high contrast and definition from the lunar surface, Saturn's rings, or deep sky objects will be within your telescope's capabilities.
The FCD100 range also features a dual speed (10:1) 2.5" Hexagonal focuser for extra smooth and precise focusing, a step up from standard crayford focusers found in cheaper makes. The saxon FCD100 127mm Apochromatic ED Refractor Telescope weighs 7.75kg without accessories, which is suitable as a primary lunar, planetary or deep sky astrophotography. You can also use it as a high-powered guide scope. The telescope includes a 2" dielectronic diagonal with 1.25" adapter which accepts both 2" and 1.25" sized eyepieces and accessories. The diagonal measures at 99% reflectivity to maximise light transmission, and is engineered to accept 2" filters on the telescope side and a brass compression ring on the eyepiece size.
