Boasting a swift f\/4 focal ratio, this astrograph is can produce an exposure 6x faster than the average 8-inch f\/10 Schmidt Cassegrain telescope. Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy. \u003cbr\u003e\u003cbr\u003eLike all Sky-Watcher reflectors, the Quattro imaging Newtonian features borosilicate mirrors coated with Sky-Watcher’s proprietary Radiant™ Aluminum Quartz (RAQ™), producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watcher’s signature glossy metal-flake Black Diamond finish. The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an optional coma corrector is available for those who want to take their imaging to the next level.\u003cbr\u003e\u003cbr\u003eIncluded with the Quattro imaging Newtonian is a 10:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapter, a 9x50 finderscope, tube rings, and a D-style dovetail plate.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e305mm aperture, 1200mm focal length\u003c\/li\u003e\n\u003cli\u003eFast f\/4 focal ratio\u003c\/li\u003e\n\u003cli\u003eParabolic mirror designed for imaging with 94% reflectivity\u003c\/li\u003e\n\u003cli\u003e10:1, dual-speed, 2-inch Crayford-style focuser\u003c\/li\u003e\n\u003cli\u003eOversized secondary mirror produces greater illumination for full-frame DSLR and CCD cameras\u003c\/li\u003e\n\u003cli\u003eTube rings, mounting plate, eyepiece adapters, and 9x50 finderscope included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"spec-table\" style=\"box-sizing: inherit;

The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an optional coma corrector is available for those who want to take their imaging to the next level.\u003cbr\u003e\u003cbr\u003eIncluded with the Quattro imaging Newtonian is a 10:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapters, a 9x50 finderscope, tube rings, and a V-style dovetail plate.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e254mm aperture, 1000mm focal length \u003c\/li\u003e\n\u003cli\u003eFast f\/4 focal ratio\u003c\/li\u003e\n\u003cli\u003eParabolic mirror designed for imaging with 94% reflectivity\u003c\/li\u003e\n\u003cli\u003e10:1, dual-speed, 2-inch Crayford-style focuser\u003c\/li\u003e\n\u003cli\u003eOversized secondary mirror produces greater illumination for full-frame DSLR and CCD cameras\u003c\/li\u003e\n\u003cli\u003eTube rings, mounting plate, eyepiece adapters, and 9x50 finderscope included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"spec-table\" style=\"box-sizing: inherit;

Boasting a swift f\/4 focal ratio, this astrograph can produce an exposure 6x faster than the average 8-inch f\/10 Schmidt Cassegrain telescope. Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy. \u003cbr\u003e\u003cbr\u003eLike all Sky-Watcher reflectors, the Quattro imaging Newtonian features borosilicate mirrors coated with Sky-Watcher’s proprietary Radiant ™ Aluminum Quartz (RAQ™), producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watcher’s signature glossy metal-flake Black Diamond finish. The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an optional coma corrector is available for those who want to take their imaging to the next level.\u003cbr\u003e\u003cbr\u003eIncluded with the Quattro Newtonian is a 10:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapters, a 9x50 finderscope, tube rings, and a V-style dovetail plate.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e205mm aperture, 800mm focal length\u003c\/li\u003e\n\u003cli\u003eFast f\/4 focal ratio\u003c\/li\u003e\n\u003cli\u003eParabolic mirror designed for imaging with 94% reflectivity\u003c\/li\u003e\n\u003cli\u003e10:1, dual-speed, 2-inch Crayford-style focuser\u003c\/li\u003e\n\u003cli\u003eOversized secondary mirror produces greater illumination for full-frame DSLR and CCD cameras\u003c\/li\u003e\n\u003cli\u003eTube rings, mounting plate, eyepiece adapters, and 9x50 finderscope included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"spec-table\" style=\"box-sizing: inherit;

fast-focal-ratio aspherical Cassegrain astrograph SCA260, Sharpstar has been tried again and again to optimize it.\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003eThe optimized SCA260 is still designed with aspherical mirror which entails much more sophisticated research and development. The process of producing, manufacturing and testing is more complicated compared with that of an ordinary reflective mirror,and the Pyrex-like material used is more stable than those traditionally used. The telescope is wrapped with durable carbon fiber material,which is lightweight, durable, and beautiful.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr\u003e\n\u003cdiv\u003eBoth the primary and secondary mirrors of SCA260 wear enhanced aluminum coatings, which ensure they can achieve a high reflectivity of more than 95%. We further simplify the optical axis mechanical structure.\u003cbr\u003eA 3\" large corrector, featuring a three-element lens structure, is laid in the optical path, enabling the whole optical system to better achieve full-frame imaging and control the vignette.\u003cbr\u003e\u003cbr\u003eThe delicately pierced handle bar is completely made from CNC-manufactured aluminum, which can be used as a base for the attachment of other accessories, optimizing the supporting mechanical construction and decreasing its weight.\u003cbr\u003e \u003cbr\u003eBased on the original, we have upgraded the travel length of the 3.35\" dedicated focuser to 50mm for greater practicability. We have also upgraded the load of the focuser to allow you to add the accessories as you like, ensuring no slippage and smooth operation when shooting with accessories.\u003cbr\u003e \u003cbr\u003eWe also added a 360 ° rotator at the rear back of the focusing device, so we don't have to worry about the EAF data line getting entangled in the process.
