Takahashi TSA-120 Triplet APO Refractor

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.

Top-notch optics, light OTA, reasonable price for premium scope

After much analysis I chose the Tak TSA 120 because it has the following attributes: 1. Premium Optics by a manufacturer with a rock solid reputation 2. Light weight (very important - many benefits here) 3. In the 120mm - 130mm aperture range 4. Reasonable price for premium scope There were other scopes that came close, but the TSA 120 seemed to be the only scope that had all these attributes, especially the light weight! I use this for visual and AP and it does not disappoint. I love the views and the photos are always beautiful, pinpoint clear, perfect color, and a flat wide field. I can use the f/5.6 reducer @ 672mm for wider field and shorter exposures or sue the native 900mm f7.7. The results are always satisfying. I was hard-pressed to find a scope with similar aperture, equivalent premium optics, and weighing only 12 lbs! For my needs, the TSA 120 is perfect, I love it, and will probably keep it for life.
