60PHQ Astronomical Telescope Refracting Astronomical Telescope for Askar

Description 60PHQ Astronomical Telescope Professional High Definition Refracting Astronomical Telescope for Askar Description: – Askar introduces the brand-new 80PHQ refractive astronomical telescope. And it’s the second long-focal-ratio astronomical telescope from the PHQ family. – 80PHQ inherits the optical design of the PHQ series, 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 astronomical telescopes from PHQ series are integrated lens combination design rather than simply placing three major lenses and a corrector together in a line. In another word, 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. – As a great mixture, 80PHQ is equipped with a 4-section adapter, convenient for users to connect different types of accessories. So it’s a great helper in astronomical photography. Besides, its special lens deign and powerful flat-field capacity make a crucial contribution to the high-quality imaging results, greatly reducing the impact of spherical and chromatic aberrations. – 80PHQ is also a novice-friendly device. Keep in mind that the distance from the bottom of M68 × 1 external screw thread to the focal plane is 155mm, and you can literally attach any accessories within this limit. You don’t have to calculate the back focus distance, which effectively simplifies the operation. – Askar 80PHQ is a cost-effective refracting astronomical telescope. It boasts special and fantastic vantages in both mechanical and optical design. As an f/7.5 refractor, it can function well by virtue of its flat-field ability and rigorous optical performance.
