ASKAR FMA F180 PRO f/4.5 Astrograph Camera Lens - Triplet APO Refractor Telescope with f/4.5 reducer/flattener

To provide customers with more options, Askar has launched the new FMA180 pro. FMA180 pro is similar to the FMA180 in optical design. The objective lens features a sextuplet air-spaced APO design and includes two pieces of ED glass, providing excellent correction of chromatic aberration. In addition to visual observations, the FMA180 pro is specially optimized for astrophotography. Compared to FMA180, FMA180 pro adds a finder base and a 360° rotator. What' s more, the focuser is designed as internal focusing which promotes its stability and ensures its performance in use as a delicate, high-quality, and compact astrograph.
