Askar 80PHQ 80/600 f/7,5 APO quadruplet

The Askar 80PHQ is an exceptional astrograph designed to cater to both amateur astrophotographers taking their first steps into the field and seasoned professionals seeking a reliable optical tube. Serving as an alternative to the 107PHQ telescope, this model offers a convenient solution for mobile observation and photography setups, requiring minimal assembly.

At the core of this telescope lies a four-element apochromatic optics system with an air gap. To ensure optimal correction of chromatic aberrations, Askar's designers incorporated a technique employed in high-end apochromats, utilizing two lenses made of low-dispersion (ED) glass. Not only does this deliver excellent color reproduction, but it also results in negligible field curvature. As a result, even without the use of an additional flattener, images at the edges of the frame remain distortion-free.

The Askar 80PHQ is not limited to astrophotography alone. With the inclusion of an angular adapter or 1.25" eyepieces, this instrument enables engaging visual observations as well.

In addition to its impeccable optical performance, the Askar 80PHQ boasts top-notch mechanical components characterized by quality and precision. The sturdy focuser allows for the installation of even the heaviest astronomical cameras, while the CNC-machined mounting rings and Vixen foot guarantee utmost stability for the tube.
