We are pleased to introduce the new EVOSTAR-80EDX model,  which is the result of several very useful mechanical improvements. Presented in its stunning new white and green livery, the EVOSTAR-80EDX is a superb instrument for both imaging and visual use, with the necessary accessories.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe new EVOSTAR-80EDX model now includes an enlarged 2.8” indexed focuser drawtube with a built-in 360° rotatable adaptor, a retractable dew shield and a convenient carrying handle.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFeaturing the same great proprietary f\/7.5 matched optics as the previous model, including one premium Japanese Ohara FPL-53 ED glass lens element which virtually eliminates chromatic aberration.

Due to less glass in their construction, they are also usually much lighter weight and more convenient to handle than an equivalent aperture triplet or other multi-element ED refractor designs.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePlease note: Supplied without eyepiece, star diagonal \u0026amp; finderscope.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e\u003cimg\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOptics\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eObjective Lens Diameter\u003c\/td\u003e\n\u003ctd\u003e80 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTelescope Focal Length\u003c\/td\u003e\n\u003ctd\u003e600 mm (f\/7.5)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eObjective Design\u003c\/td\u003e\n\u003ctd\u003eMulti-Coated Objective Lens (MHTC coatings)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHighest Practical Power\u003c\/td\u003e\n\u003ctd\u003ex240\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImage Height\u003c\/td\u003e\n\u003ctd\u003e30 mm (with optional reducer\/flattener)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFocuser\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser Type\u003c\/td\u003e\n\u003ctd\u003eDual-Speed 11:1 2\" Crayford (backlash-free)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrawtube Size\u003c\/td\u003e\n\u003ctd\u003e2.8\" Indexed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotation\u003c\/td\u003e\n\u003ctd\u003e360º rotatable adaptor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMechanical Features\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDew Shield\u003c\/td\u003e\n\u003ctd\u003eRetractable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Material\u003c\/td\u003e\n\u003ctd\u003eAluminium OTA with internal baffling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Rings\u003c\/td\u003e\n\u003ctd\u003eTube rings with carrying handle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDovetail Bar\u003c\/td\u003e\n\u003ctd\u003e45 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinderscope Mount\u003c\/td\u003e\n\u003ctd\u003eCompatible with all Sky-Watcher finderscopes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiagonal Compatibility\u003c\/td\u003e\n\u003ctd\u003eAccepts 2\" star diagonal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions \u0026amp; Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOTA Length (Retracted)\u003c\/td\u003e\n\u003ctd\u003e475 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOTA Length (Extended)\u003c\/td\u003e\n\u003ctd\u003e557 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (OTA)\u003c\/td\u003e\n\u003ctd\u003e4 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIncluded Accessories\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCarrying Case\u003c\/td\u003e\n\u003ctd\u003eAluminium carrying case\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTelescope tube\u003c\/li\u003e\n\u003cli\u003eLosmandy-D type Dovetail\u003c\/li\u003e\n\u003cli\u003eMounting Case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cp\u003eSky-Watcher 2-Year Warranty\u003c\/p\u003e","brand":"Sky-Watcher","offers":[{"title":"Default Title","offer_id":48759256088805,"sku":"SW-S11135","price":1040.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/1_f4691c53-2e4b-4190-8abe-5ccc91078741.webp?v=1775934552","url":"https:\/\/astronomyplus.com\/products\/sky-watcher-edx-80mm-apo","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
