The Takahashi TSA 120 APO Triplet Refractor Telescope is innovation at its finest. With superior quality in optics incorporated in a portable package, the TSA 120 APO is versatility at its best. There are three elements in the Triplet design, two extreme quality crown and flint glass with an FPL-53 Extra-Low Dispersion glass sandwiched in between. Refractor designs typically use oil in between elements but the TSA 120 APO by Takahashi does not!

The Takahashi TSA 120 APO is Super Apochromatic. Being Super Apochromatic means being free from those strange violet glows which often accompany planets or bright stars. The construction of the lens cells was made to withstand transport and if so desired, can be fully collimated to make adjustments. The optics of on the TSA 120 APO by Takahashi are near perfection. Producing color free images amaze almost every planetary, lunar and deep sky observer with very high contract images with pinpoint stars.
