The saxon FCD100 102mm Apochromatic ED Triplet Refractor Telescope is a serious instrument for those who want to see the universe without optical compromises. By using high-grade Japanese Hoya FCD100 glass in a triplet lens design, this optical tube assembly (OTA) virtually eliminates the purple fringing often seen in standard achromatic scopes. With a 102mm aperture and 714mm focal length, the saxon 102/714 APO collects enough light to reveal faint deep-sky treasures while maintaining the sharpness needed to resolve intricate details on the Moon and planets. The proprietary EMD coatings further enhance contrast, ensuring that the view through the eyepiece is as distinct and vibrant as possible.
Beyond the glass, the build quality is designed to support a smooth observational experience. The telescope features a heavy-duty 2.5" Hexagonal dual-speed focuser, which handles heavy eyepieces or cameras with ease and allows for ultra-fine focus adjustments. Weighing in at 5.1kg, the saxon FCD100 102mm Refractor Telescope is substantial enough to remain stable during imaging sessions yet manageable for transport to dark sky sites. The included 2" dielectric diagonal boasts 99% reflectivity, maximising light transmission to your eye, while the comprehensive accessory kit ensures you have everything needed to start observing right away.
