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.
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.
The TSA-120 is the second in the new TSA line of Takahashi triplet apochromats. The color free performance will delight the lunar, planetary and deep sky observer with very high contrast images and pin point stars.
Not only is the TSA-120 a great visual instrument, it can be converted into a flat field f/7.3 or an f/5.3 wide field imaging platform for a CCD camera or digital SLR. The addition of the optional camera angle adjuster allows the image to be rotated 360° without loss of focus. The camera angle adjuster is also very handy for visual applications to position the ocular or bino viewer in the best most comfortable position.
The TSA-120 is a fairly compact, high quality, apochromatic, versatile Takahashi, made for the refractor enthusiast who wants a very high quality instrument in a relatively compact package.
Note: Takahashi optical tubes are sold without tube holder (rings), finderscope, star diagonal, eyepiece, reducer, flattener, extender, mount and tripod. These extra items are sold separately.
