Askar FMA180 PRO Features

 

To provide customers with more options, Askar has launched the new FMA180 pro.

 

Askar FMA180 PRO

 

FMA180pro 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 40mm, a focal ratio of f/4.5, and a focal length of 180mm.

 

Askar FMA180 PRO

 

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.

 

 Askar FMA180 PRO

 

The FMA180 pro comes with an M48 adapter at the rear end, and the back focus is the standard 55mm. 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.

 

Askar FMA180 PRO

 

In a word, FMA180 pro is a compact astrograph for astrophotography with more integrated functions and a more dedicated design.

  • กล้องดูดาว Askar 80PHQ 80mm f/7.5 Quadruplet Flat-Field Astrograph

    กล้องดูดาว Askar 80PHQ 80mm f/7.5 Quadruplet Flat-Field Astrograph

    กล้องดูดาว Askar 80PHQ 80mm f/7.5 Quadruplet Flat-Field Astrograph #80PHQ

    80PHQ inherits the optical design of the PHQ family, adopting a 3+1 quadruplet lens structure which contains two pieces of ED glass that can effectively reduce chromatic aberration and enhance clarity and sharpness. It’s worth mentioning that all astrographs from the PHQ family come with an integrated lens combination rather than simply placing three major lenses and a corrector together in a line. In other words, the whole optical system cannot solely perform without any piece of these lenses. This structure design leads to a more rational lens arrangement, better vignette control and superior image quality. The focal ratio of 80PHQ is f/7.5. It’s a “long” focal-ratio astrograph compared with other counterparts from Askar. It’s a little bit longer even compared with 107PHQ which is f/7 in focal ratio.
