To provide customers with more options, Askar has launched the FMA180 pro.Similar to the FMA180 in optical design, the FMA180 pro adopts a sextuplet air-spaced APO design with three lenses in front and three in the rear, two of which are ED glass, providing excellent correction of chromatic aberration, which lays the foundation for high-quality astrophotography and observation. It has an aperture of 40 mm, a focal ratio of f/4.5, and a focal length of 180 mm.

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.The FMA180 pro comes with an M48 adapter at the rear end, and the back focus is the standard 55 mm. 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.In a word, FMA180 pro is a compact astrograph for astrophotography with more integrated functions and a more dedicated design.
Practical tip from APM - how to achieve good focusing for astrophotography:
The FMA180 pro is equipped with a helical focuser. Although this works, it is relatively coarse. Especially with very high-resolution astro cameras, very good focusing on the star soon becomes a game of patience. The TeleFokus75 solves the problem. It offers a very precise and, above all, reproducible fine adjustment.
