Its 120 mm objective lens consists of three air-spaced elements, one of which is made of ED S-FPL53 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>Prepare Your Equipment<\/h3>\n<p>The rack-and-pinion focus mechanism allows you to adjust the focus to match your observing accessories or camera mount. The 125-mm-diameter outer tube allows you to choose a mount that is compatible with this telescope.<\/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 part number refers to the optical tube, including its objective lens and focusing system.
