Takahashi TS-120 120 APO Refractor with 3-inch FeatherTouch Focuser from SI
The TSA-120 Triplet APO Refractor Telescope with a 3-inch FeatherTouch focuser from Starlight Instruments delivers superior quality optics, all in a portable package! This air-spaced triplet design achieves a high level of apochromatic performance for lunar, planetary and deep sky observing and imaging, delivering very high contrast images with pinpoint stars. Inside the precision-crafted lens cell, you'll find three elements, an FPL-53 Extra-low Dispersion (ED) glass lens placed between two air-spaced extreme quality crown lenses. This Telescope’s ED triplet optics yield excellent high-contrast images, free of chromatic aberration’s violet glow, which often accompany bright stars and planet. The TTK-120's short tube make transport and versatile accessory assemblies possible, especially for those using important length. The system chart will guide you through the TTK-120's versatile assemblies which all fulfill the requirements of rigidity and flexibility needed by the new imaging devices, including SLR/DSLR or CCD cameras. KEY FEATURES Apochromatic Triplet ED Refractor Optics- 120 mm aperture, 900 mm focal length, f/7.5 refractor- Multicoated Optics- coated with broadband anti-reflection materials for optimal light transmission and contrast. Retractable Lens Hoods- reduces dew formation on the lens and improves contrast by shielding the lens from off-axis ambient light. 3-inch FeatherTouch focuser from Starlight Instruments. Compatibility and Versatility- compatible with several flatteners, reducers, and extenders, including the TOA-35 Reducer, which converts the telescope to a f/5.3 imaging platform with a 44 mm image circle. (Note: Image shows this scope with the Takahashi focuser for sample only, you can purchase that set-up under #TK-TTK12010.)
