Askar新推出的FMA180 pro是一款功能更加一體化的小型攝星鏡,口徑40mm,焦比f/4.5,焦距180mm。在光學設計與結構上採用前三後三的六片式全分離 APO 設計,其中兩片為ED玻璃,色差控制非常優異。與FMA180相比,其增加了尋星鏡基座與360°旋轉器,並將調焦器設計為內調焦型,增加了調焦器的穩定性,更保障其作為小巧、高品質的小型攝星鏡的使用性能。多功能支架使其既能作拍攝使用,也能在卸下Vixen窄型鳩尾板後直接作為導星鏡安裝到其他望遠鏡的尋星鏡基座上。

Askar's new FMA180 pro is an all-in-one compact stargazer with a 40mm aperture, focal ratio of f/4.5 and a focal length of 180mm, featuring a six-piece fully discrete APO design with two pieces of ED glass for excellent chromatic aberration control. Compared to the FMA180, it has an additional finders base and 360° rotator. 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. The multifunctional base can not only be used for astrophotography but also be mounted onto other telescopes' finder bases as a finder scope after the Vixen dovetail plate is detached.
