PREORDER Askar 65PHQ 0.75× Full-Frame Reducer

Askar 65PHQ 0.75× Full-Frame Reducer

Askar’ s new-launched 65PHQ 0.75× full-frame reducer has a quadruplet design. The 0.75× reduction gives 65PHQ a shortened focal ratio of f/4.8 and a shortened focal length of 312mm. This reducer, connected with the astrograph, can effectively shorten the exposure time and dramatically increase your field of view, bringing more convenience and possibilities for your deep-sky astrophotography. The backfocus is the standard 55mm. It comes with two thread adapters of M54, M48 with a built-in M48×0.75 2” filter thread, so it is convenient for connection.

PREORDER กล้องดูดาว Askar 65PHQ 65mm f/6.4 Quadruplet Flat-Field Astrograph

กล้องดูดาว Askar 65PHQ 65mm f/6.4 Quadruplet Flat-Field Astrograph #65PHQ

65PHQ is a flatfield astrograph newly launched after 80PHQ, 107PHQ, and 130PHQ. 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 it with any possible imaging accessories, make the target stay at the focus, and then the whole optical system is perfect for imaging.

65PHQ has a smaller size than other PHQ astrographs. 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 the astronomical shooting. It supports the full-frame image circle and has a fine spot diagram with tiny distortions of the peripheral stars.

กล้องดูดาว Askar 80PHQ 80mm f/7.5 Quadruplet Flat-Field Astrograph

กล้องดูดาว Askar 80PHQ 80mm f/7.5 Quadruplet Flat-Field Astrograph #80PHQ

80PHQ inherits the optical design of the PHQ family, adopting a 3+1 quadruplet lens structure which contains two pieces of ED glass that can effectively reduce chromatic aberration and enhance clarity and sharpness. It’s worth mentioning that all astrographs from the PHQ family come with an integrated lens combination rather than simply placing three major lenses and a corrector together in a line. In other words, the whole optical system cannot solely perform without any piece of these lenses. This structure design leads to a more rational lens arrangement, better vignette control and superior image quality. The focal ratio of 80PHQ is f/7.5. It’s a “long” focal-ratio astrograph compared with other counterparts from Askar. It’s a little bit longer even compared with 107PHQ which is f/7 in focal ratio.
