Askar FMA180 PRO APO Professional Deep Space Astronomical Telescope with Two Extra-low Dispersion Glasses
Description:
- The optical design structure of FMA180 PRO is similar to that of FMA180. The main lens adopts a six piece fully separated APO design, with two of them being ED (Extra-low dispersion) glasses, which has excellent color difference control and lays the foundation for high-quality photography and observation. Its caliber is 40mm, focal ratio is f/4.5, and focal length is 180mm.
- In addition to being used for visual observation, the FMA180 PRO has been optimized for astronomical photography. Compared with the FMA180, it adds a finder-scope base and a 360 degree rotator, and upgrades the focusing device to a new integrated internal focusing system, which increases the stability of the focusing device and ensures its performance as a compact, high-quality small star lens.
- The rear end of the telescope is equipped with an M48 connector, and the rear intercept is still the standard 55mm. The multifunctional support enables it to be used for shooting, and can also be directly installed as a star guide lens on the base of other telescopes' finder-scope after the Vixen narrow dovetail plate is removed.
