TSA-120

The TSA-120 is a 120 mm apochromatic f/7.5 refractor with a focal length of 900 mm, featuring a retractable lens hood and a 2.7 inch rack and pinion focuser. This air-spaced ED triplet design places an ED glass lens between two lenses with air spacing in between, achieving a high level of apochromatic performance for both visual observation and imaging. This portable 15.4 lb. package delivers sharp images of lunar and planetary details with realistic and highly saturated color, free from chromatic aberration's violet haze of spurious color. The TSA-120 is a lightweight, compact and economical refractor whose performance is similar to that of the TOA series, Takahashi's flagship models.
