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. 


As part of the Mars Opposition promotion, customers will receive the Extender ED 1.5X (TKA27595) and the 35 Flattener (TKA31582) with each TSA-120.  These items normally cost an additional $1,060 when purchased separately.




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).
