The TSA series is a member of Takahashi’s line of triplet refractors. In the TSA design, an ED glass lens is placed between two lenses, with air spacing in between. The resulting system achieves a high level of apochromatic performance for both visual observation and imaging.

TSA-120

The TSA-120 is a 120 mm apochromatic f/7.5 refractor with a focal length of 900 mm. It features a retractable lens hood and a 2.7 inch rack and pinion focuser. The TSA is 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.

Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).

Second TSA triplet apochromat
Very high order of color correction
Compact design only 28” long collapsed
Long back focus 227mm [8.93”] to accommodate bino viewers and any 2” diagonal

The TSA-120 is the second triplet apochromat in the TSA Series. Its superb color correction will provide high contrast images with pin point stars across the field.

The compact size of 28” allows the TSA-120 to be easily transported to remote sites.

The TSA-120 is a great scope for imaging. The TOA 35 flattener converts the 120 into an f/7.3 882mm flat field 2.6º instrument and the reducer changes it to an f/5.6 672mm
