Open Box Takahashi TSA120 Optical Tube
The TSA-120 Triplet APO Refractor Telescope 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 TSA-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 TSA-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.
