Askar 80PHQ f/7 Quadruplet APO

The Askar 80PHQ f/7 Quadruplet APO is a premium apochromatic refractor telescope designed for both astrophotography and visual observation. With its 80mm aperture and f/7 focal ratio, this telescope offers an excellent balance of light-gathering power and field of view, making it ideal for capturing wide-field deep-sky objects and for high-contrast planetary viewing.

Additional accessories may be required for optimal use in astrophotography. Check compatibility with your existing equipment.

Optical Design

---

The 80PHQ features a sophisticated quadruplet lens design, incorporating four precisely aligned elements to deliver superior color correction and sharp, high-contrast images. This apochromatic design effectively eliminates chromatic aberration, ensuring true-to-life colors in both visual and photographic applications.

Imaging Performance

---

With its 80mm aperture and 560mm focal length (f/7), the 80PHQ excels in wide-field astrophotography. It's particularly well-suited for capturing large nebulae, star clusters, and expansive galaxy fields. The fast f/7 focal ratio allows for shorter exposure times, making it easier to gather data even under less-than-ideal sky conditions.

Build Quality

Constructed with high-quality materials, including a precision-machined aluminum tube and dew shield. The robust build ensures stability and minimizes flexure, critical for long-exposure astrophotography and precise visual observations.

Focuser

Equipped with a high-precision dual-speed focuser, allowing for fine adjustments necessary for achieving perfect focus in both visual and photographic applications. The focuser is designed to handle heavy imaging payloads without slipping.

Versatility

While optimized for astrophotography, the Askar 80PHQ also excels in visual observations. It offers breathtaking wide-field views of star fields, nebulae, and larger deep-sky objects, as well as detailed views of the Moon and planets.

Portability

With its compact size and lightweight design, the 80PHQ is highly portable, making it an excellent choice for astronomers who frequently travel to dark-sky sites or engage in mobile astrophotography.

Accessories and Compatibility

The telescope is typically equipped with standard connections for attaching various accessories. It's compatible with a wide range of astrophotography equipment, including field flatteners, focal reducers, and camera adapters.
