Askar 80PHQ Astrograph

Discover the Askar 80PHQ astrograph, a state-of-the-art instrument in the PHQ family, designed for demanding astrophotographers looking for quality, performance and ease of use. With its advanced optical concept and refined design, the Askar 80PHQ is the ideal tool for capturing the wonders of the deep sky with unrivalled precision.

High Quality Optical Design

The Askar 80PHQ astrograph adopts a unique quadruplet (3+1) structure with two ED (Extra-low Dispersion) glass elements, which effectively reduces chromatic aberrations and guarantees images of exceptional clarity and sharpness. Unlike many other models, the 80PHQ's optics are an integrated combination of lenses, offering a more rational arrangement, better control of vignetting, and superior image quality. With a focal ratio of f/7.5, this astrograph offers a flat field without the need for back focus calculation, making installation and use extremely simple.

Unbeatable technical specifications
