Askar新推出的FMA180 pro是一款功能更加一体化的小型摄星镜，口径40mm，焦比f/4.5，焦距180mm。在光学设计与结构上采用前三后三的六片式全分离 APO 设计，其中两片为ED玻璃，色差控制非常优异。与FMA180相比，其增加了寻星镜基座与360°旋转器，并将调焦器设计为内调焦型，增加了调焦器的稳定性，更保障其作为小巧、高品质的小型摄星镜的使用性能。多功能支架使其既能作拍摄使用，也能在卸下Vixen窄型鸠尾板后直接作为导星镜安装到其他望远镜的寻星镜基座上。

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.
