Brief Introduction
The 180 APO PRO astronomical telescope is adopted the classic triplet elements, air-spaced apochromatic design, which includes two pieces of specially customized super ED glass. The objective lens is made using the traditional slow polishing process and undergoes high-quality processing, as well as double-checking by artificial star dots and laser interferometers to ensure quality. The focal ratio of the 180 APO PRO is F/7, with excellent chromatic aberration control. In addition, a dedicated 0.8x reducer has been independently made for the 180 APO PRO to fully meet the needs of medium format photography.
