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 (extra-low dispersion) glass, providing excellent correction of chromatic aberration. In addition to visual observations, the FMA180 pro is specially optimized for strophotography. 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.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003e\u003cimg
