Instead of buying extra flatteners, calculating the backfocus of flattener or making tedious connection to match the distance, astrophotographers can simply equip it with any possible imaging devices, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e130PHQ has a larger size than 107PHQ, with an aperture 23mm larger than 107PHQ. 130PHQ has a focal ratio of f\/7.7 which is longer than 107PHQ’ s f\/7, and a focal length of 1000mm. The quadruplet lens with two ED glasses offers excellent control of chromatic and other aberrations. With its self-flattening design, 130PHQ offers strong advantages in astronomical shooting. It supports a medium frame 60mm image circle, has a fine spot diagram with tiny distortion of the peripheral stars, and its central RMS radius is less than 2 microns.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e130PHQ comes with a telescopic lens hood, a high quality CNC machined and painted tube and attractive decorative parts. The 3.4\" rigid focuser comes with M68, M54, and M48 adapters and a finder base. When used with the 3\" 0.7 x flat field reducer, the telescope can reach a focal ratio of f\/5.4 and a focal length of 700mm, effectively reducing exposure time. The multifunctional handle comes with a central slot for attaching an M6 screw with an M6 screw hole. Standard Losmandy dovetail plate, together with sturdy double tube ring, is perfectly suited for viewing and shooting.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e\u003cspan style=\"color: #444444;

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.
