Askar 65PHQ

The Askar 65PHQ is a flatfield astrograph which joins the Askar lineup of the 80PHQ, 107PHQ, and 130PHQ. Available in the company’s traditional green and white color combo, the company is also offering a limited quantity 2023 pink version.

Askar 65PHQAs the company notes about the PHQ telescopes, “Instead of buying extra flatteners, calculating the back focus of the flattener, or making a tedious connection to match the correct distance, astrophotographers can simply equip the telescope with any possible imaging accessories, make the target stay at the focus, and then the whole optical system is perfect for imaging.”

The Askar 65PHQ has been designed to perform in a smaller format than the other PHQ astrographs. The 65PHQ has a focal ratio of f/6.4 and a focal length of 416mm. Instead of the quadruplet structure of other PHQs, the 65PHQ is a quintuplet with two ED glasses which offers excellent control of chromatic and other aberrations. With its self-flattening design, 65PHQ offers strong advantages in astronomical imaging as it supports a full-frame image circle and has a fine spot diagram with tiny distortions of the peripheral stars. And as with Askar’s other PHQ telescopes, there is no need to calculate the back focus or buy a separate flattener.

The OTA weighs just 2kg and the full package with tube rings, etc. weighs in at 2.8kg. The 2.5” rigid focuser comes with a newly designed 360° rotator with scales and a finder base. M68, M54, and M48 camera adapters are also included and the M48 adapter has a 2” female thread for installing filters.

The Askar 65PHQ is also a nice choice for visual observation. With different diagonals and various eyepieces it can achieve perfect focus. It can even be used to observe planets with a super-high magnification eyepiece.
