The \u003cstrong\u003eEdge HD\u003c\/strong\u003e optical system combines the proven compactness of classic Schmidt-Cassegrain telescopes with a newly engineered optical design that produces a \u003cstrong\u003efully flat focal plane\u003c\/strong\u003e across the entire field of view — critical for achieving pinpoint star images to the very edge of the sensor, with image quality on par with dedicated astrographs.\u003c\/p\u003e\n\n  \u003ch2\u003eVisual Observation: Pinpoint Stars to the Field Edge – Even with Wide-Angle Eyepieces\u003c\/h2\u003e\n  \u003cp\u003eDuring visual use, Edge HD optics deliver \u003cstrong\u003epinpoint star images to the edge of the field\u003c\/strong\u003e even when paired with ultra-wide-angle 2-inch eyepieces — a result rarely achievable with conventional Schmidt-Cassegrain telescopes. The \u003cstrong\u003eStarbright XLT\u003c\/strong\u003e multi-coating maximizes light transmission and ensures high contrast on both planetary targets and deep-sky objects, making the Edge HD 1100 a versatile instrument for extended observing sessions.\u003c\/p\u003e\n\n  \u003ch2\u003eAstrophotography: Flat Field and Aberration-Free Imaging on Full-Frame Sensors\u003c\/h2\u003e\n  \u003cp\u003eFor astrophotography, the Edge HD system produces \u003cstrong\u003eaberration-free images across the entire field\u003c\/strong\u003e of CCD and DSLR cameras, including full-frame format sensors. The flat focal plane eliminates the field curvature inherent in classic Schmidt-Cassegrains, allowing full use of the sensor surface with no coma, astigmatism or focus fall-off at the corners. The Edge HD 1100 is compatible with the \u003cstrong\u003eFastar\/Hyperstar system\u003c\/strong\u003e, which converts the telescope into a fast focal ratio instrument for wide-field imaging.\u003c\/p\u003e\n\n  \u003ch2\u003eModularity and Focal Length Range from 560 to 12,000 mm\u003c\/h2\u003e\n  \u003cp\u003eThe Edge HD 1100 is designed for \u003cstrong\u003emodular use with a wide range of accessories\u003c\/strong\u003e — including focal reducers, Barlow lenses and third-party cameras — enabling operation across a focal length range of 560 to 12,000 mm. This flexibility makes it suitable for a broad range of observing and imaging configurations, from high-magnification planetary work to long focal length imaging of nebulae and galaxies.\u003c\/p\u003e\n\n  \u003ch2\u003eThermal Equilibration, Mirror Lock and Primary Mirror Ventilation\u003c\/h2\u003e\n  \u003cp\u003eThe aluminum optical tube features \u003cstrong\u003emicrofiltered ventilation ports\u003c\/strong\u003e that accelerate thermal equilibration of the optics, reducing cool-down time in the field. The \u003cstrong\u003eprimary mirror locking system\u003c\/strong\u003e, operated by two knobs, eliminates mirror shift during focusing and long imaging sessions, ensuring stability and repeatability of the focal position throughout the night.\u003c\/p\u003e\n\n  \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n  \u003ctable\u003e\n    \u003cthead\u003e\n      \u003ctr\u003e\n        \u003cth\u003eFeature\u003c\/th\u003e\n        \u003cth\u003eDetail\u003c\/th\u003e\n      \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr\u003e\u003ctd\u003eOptical design\u003c\/td\u003e\u003ctd\u003eEdge HD aplanatic Schmidt-Cassegrain\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eAperture\u003c\/td\u003e\u003ctd\u003e280 mm\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eFocal length\u003c\/td\u003e\u003ctd\u003e2800 mm\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eFocal ratio\u003c\/td\u003e\u003ctd\u003ef\/10\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eObstruction\u003c\/td\u003e\u003ctd\u003e0.35\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eLight gain\u003c\/td\u003e\u003ctd\u003e1593x (naked eye = 1)\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eCoating\u003c\/td\u003e\u003ctd\u003eStarbright XLT\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eFocusing\u003c\/td\u003e\u003ctd\u003ePrimary mirror shift\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eFastar compatibility\u003c\/td\u003e\u003ctd\u003eYes\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eTube material\u003c\/td\u003e\u003ctd\u003eAluminum\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eMirror lock\u003c\/td\u003e\u003ctd\u003e2 knobs + primary mirror ventilation baffles\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eFocal range with accessories\u003c\/td\u003e\u003ctd\u003e560 – 12,000 mm\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eOTA length\u003c\/td\u003e\u003ctd\u003e610 mm\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eOTA weight\u003c\/td\u003e\u003ctd\u003e13 kg\u003c\/td\u003e\u003c\/tr\u003e\n    \u003c\/tbody\u003e\n  \u003c\/table\u003e\n\n  \u003ch2\u003eIncluded Accessories\u003c\/h2\u003e\n  \u003ctable\u003e\n    \u003cthead\u003e\n      \u003ctr\u003e\n        \u003cth\u003eAccessory\u003c\/th\u003e\n        \u003cth\u003eDetail\u003c\/th\u003e\n      \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr\u003e\u003ctd\u003eEyepiece\u003c\/td\u003e\u003ctd\u003eLuminos 23 mm (102x) – 2-inch barrel\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eFocuser\u003c\/td\u003e\u003ctd\u003e2″ \/ 1.25″ (31.8 mm)\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eDiagonal\u003c\/td\u003e\u003ctd\u003eMirror diagonal, 2-inch barrel\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eFinderscope\u003c\/td\u003e\u003ctd\u003e9×50 mm with quick-release bracket\u003c\/td\u003e\u003c\/tr\u003e\n      \u003ctr\u003e\u003ctd\u003eMounting bar\u003c\/td\u003e\u003ctd\u003eDovetail bar compatible with CGE \/ Losmandy \/ NEQ6\u003c\/td\u003e\u003c\/tr\u003e\n    \u003c\/tbody\u003e\n  \u003c\/table\u003e\n\n\u003c\/div\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":56922547716427,"sku":"CSCE91050-XLT","price":4907.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0886\/1981\/1147\/files\/telescopio_celestron_edge_hd_11_schmidt_cassegrain.jpg?v=1774948621","url":"https:\/\/adriasky.it\/en\/products\/celestron-edge-hd-11-cge-aplanatic-sct-280mm-ota","provider":"Adriasky","version":"1.0","type":"link"}
