Its 120 mm objective lens consists of three air-spaced elements, one of which is made of S-FPL53 ED glass. This design reduces chromatic aberration to preserve sharp detail. At its native focal length, the 900 mm focal length corresponds to an F\/D ratio of 7.5.<\/p>\n<p>The three-group barrel is designed to maintain optomechanical stability during transport and in the face of temperature fluctuations during use.<\/p>\n<h3>Feather Touch Focus<\/h3>\n<p>This version comes with a 3-inch Starlight Instruments Feather Touch eyepiece holder, engraved with \u00abMade for Takahashi.\u00bb Its 1\/10 gear ratio facilitates fine adjustments. The mechanism is motorizable, and its oversized construction is suitable for photographic setups with a camera and filter wheel.<\/p>\n<p>The adaptation retains the accessory mounting configurations of the standard TSA-120, allowing the use of the connection diagrams provided for the instrument.<\/p>\n<h3>Adjusting the field of view<\/h3>\n<p>The optional TOA-35FL corrector offers a focal length of 882 mm and a corrected image circle of 40 mm. The TOA-35RD reducer is also among the photographic accessories available for the TSA-120. The choice of rings and the distance to the sensor depends on the corrector or reducer selected.<\/p>\n<h3>Content and Editing<\/h3>\n<p>This kit includes the optical tube with its objective lens, Feather Touch focusing mechanism, retractable dew shield, and adapter for the Takahashi finder mount.
