And it’s the second longest-focal-ratio astrograph from the PHQ- family.\u003c\/p\u003e\n\u003cp\u003eA pair of clamshell-style CNC-manufactured black tube rings tightly hold the OTA. So you can just turn two locking screws to loosen or tighten the tube rings, simplifying the setup by avoiding the frequent use of small tools like Allen wrenches or socket head screws.\u003cbr\u003eThe bright green dust cap, handle, locking screws, focusing knob and decorative rings add more energy and vitality to the otherwise deep and profound astrograph. White and green is the classic combination for PHQ series.\u003c\/p\u003e\n\u003cp\u003eThere is a 3\" rack-and-pinion rigorous focuser on the rear end of the telescope. It’s a smooth focusing unit with dual-speed adjustment. 80PHQ’s rotator is marked with precise graduation which makes your previous subjective adjustment more accurate.\u003c\/p\u003e\n\u003cp\u003e80PHQ 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.\u003c\/p\u003e\n\u003cp\u003eSome users may be frustrated that it’s hard to make a trade-off between 107PHQ and 80PHQ, since there seems to be so much in common. And especially for those who are new to astrophotography, the complicated designations and confusing numbers are really a major obstacle when they hopefully try to pick out just the proper one from oceans of dazzling products.\u003cbr\u003e\u003cbr\u003eIndeed, 170PHQ and 80PHQ are similar in many aspects partially because they are both the newly-developed refractive astrographs from the same family. However even if they all have excellent mechanical design and sophisticated optical system, there are noticeable differences between these two.\u003c\/p\u003e\n\u003cp\u003eAt the first glance, Askar 80PHQ is much more compact. 107PHQ is 603mm in length and weighs 5.7kg whereas 80PHQ is 448mm in length and weighs 3.9kg. So if your equatorial mount is not capable of holding heavy telescopes, or if you are quite tired of carrying a bulky long focal-ratio telescope travelling all around, then 80PHQ may be a great option.\u003c\/p\u003e\n\u003cp\u003eLike 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAperture size：80mm\u003c\/li\u003e\n\u003cli\u003eFocal length：600mm\u003c\/li\u003e\n\u003cli\u003eFocal ratio：f\/7.5\u003c\/li\u003e\n\u003cli\u003eObjective lens：Quadruplet air-spaced APO (including two ED glass)\u003c\/li\u003e\n\u003cli\u003eImage circle：44mm\u003c\/li\u003e\n\u003cli\u003eMaximum accessory connection (with the focuser fully retreated)：\n\u003cul\u003e\n\u003cli\u003e1.
