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 crown lenses. The telescope’s ED triplet optics yield excellent high-contrast images, free of chromatic aberration’s violet glow, which often accompany viewing brighter objects like the Moon, planets and bright stars.
The TSA-120's short tube make transport and versatile accessory combinations possible. Takahashi's system chart will guide you through the TSA-120's vast array of various accessories for both visual observing and digital imaging including DSLR's, Mirrorless 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 Hood - reduces dew formation on the lens and improves contrast by shielding the lens from off-axis ambient light.
- 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.
