- The overall finish of 80PHQ is evenly painted. The ivory and flawless coating of the main tube feels comfortably pimply, which can not only increase your grip, preventing the telescope from slipping off from your sweaty hands, but also improve its texture, avoiding the tedious monotony.
- 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 PHQ- family come with an integrated lens combination 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.
- 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.
- Like 107PHQ, you don't need to calculate the back focus distance within the connection limit. Besides, users don't need to add an extra 1× flattener due to its powerful flatfield optical design, which simplifies the operation.
