Product Details

  • The TSA-120 Triplet APO Refractor Telescope delivers superior quality optics and Takahashi performance, 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 premium 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 planets.

    The TSA-120's short tube makes transport easy. The system chart will guide you through the TSA-120's versatile accessories which all fulfill the requirements of rigidity and flexibility needed by the new imaging devices, including SLR/DSLR or CCD cameras.


    • Apochromatic Triplet ED Refractor Optics-120 mm aperture, 988 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.
    • 2.7-inch rack and pinion focuser
    • 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.
