Thanks to the \u003cstrong\u003e40mm front-mounted Etalon\u003c\/strong\u003e with a \u003cstrong\u003ebandwidth of 0.6 Ångströms\u003c\/strong\u003e or better, it enables safe observation and photography of the most dynamic details of our star: \u003cstrong\u003esolar prominences\u003c\/strong\u003e, \u003cstrong\u003esolar flares\u003c\/strong\u003e, \u003cstrong\u003espicules\u003c\/strong\u003e, \u003cstrong\u003esurface granulation\u003c\/strong\u003e and \u003cstrong\u003esunspots\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eSwitching from \u003cstrong\u003eH-alpha\u003c\/strong\u003e to \u003cstrong\u003ewhite light\u003c\/strong\u003e mode is achieved with a simple movement of the \u003cstrong\u003eDual Switch diagonal\u003c\/strong\u003e, without dismounting or replacing any components. The \u003cstrong\u003e40mm ED doublet\u003c\/strong\u003e with anti-reflection coating guarantees sharp, high-contrast images with a \u003cstrong\u003efocal ratio of f\/6.25\u003c\/strong\u003e and a \u003cstrong\u003efocal length of 250mm\u003c\/strong\u003e. Due to the limited availability of this item, it is recommended to check availability before placing an order.\u003c\/p\u003e\n\n\u003ch2\u003eH-Alpha Solar Observation: Prominences, Flares and Chromospheric Details\u003c\/h2\u003e\n\u003cp\u003eIn \u003cstrong\u003eH-alpha mode\u003c\/strong\u003e, the Acuter Luma-X 40 ED allows observation of the \u003cstrong\u003esolar chromosphere\u003c\/strong\u003e with exceptional spectral resolution. The \u003cstrong\u003e0.6 Ångström bandwidth\u003c\/strong\u003e precisely isolates the H-alpha line at 656.28nm, revealing structures otherwise invisible in white light. It is an instrument suited both to the amateur astronomer approaching \u003cstrong\u003esolar astrophotography\u003c\/strong\u003e and to the experienced observer wishing to monitor solar activity in real time.\u003c\/p\u003e\n\n\u003ch2\u003eSmartphone Adapter and Educational Use\u003c\/h2\u003e\n\u003cp\u003eThe Luma-X 40 ED is supplied with a \u003cstrong\u003euniversal smartphone adapter\u003c\/strong\u003e that allows the Sun to be photographed directly through the eyepiece, creating a photographic record of observing sessions. Thanks to its inherent operational safety, the telescope is also \u003cstrong\u003esuitable for school educational use\u003c\/strong\u003e, enabling group solar observations without any risk to students.\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\n      \u003ctd\u003eType\u003c\/td\u003e\n      \u003ctd\u003eED refractor\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOptical design\u003c\/td\u003e\n      \u003ctd\u003eED doublet\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eObjective diameter\u003c\/td\u003e\n      \u003ctd\u003e40 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFocal length\u003c\/td\u003e\n      \u003ctd\u003e250 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFocal ratio\u003c\/td\u003e\n      \u003ctd\u003ef\/6.25\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eEtalon diameter\u003c\/td\u003e\n      \u003ctd\u003e40 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBandwidth\u003c\/td\u003e\n      \u003ctd\u003e0.6 Ångströms or better\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaximum magnification\u003c\/td\u003e\n      \u003ctd\u003e80x\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOptical coating\u003c\/td\u003e\n      \u003ctd\u003eAnti-reflection\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFocuser\u003c\/td\u003e\n      \u003ctd\u003eCrayford 31.8 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e1.9 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eIncluded Accessories\u003c\/h2\u003e\n\u003cp\u003eThe Acuter Luma-X 40 ED Solar Refractor is supplied complete with: \u003cstrong\u003eDual Switch solar diagonal\u003c\/strong\u003e for H-alpha and white light, \u003cstrong\u003eHeliofind finder\u003c\/strong\u003e, \u003cstrong\u003e5-16mm zoom eyepiece\u003c\/strong\u003e (15 to 50x), \u003cstrong\u003esmartphone photo adapter\u003c\/strong\u003e and \u003cstrong\u003ecarrying case\u003c\/strong\u003e.\u003c\/p\u003e","brand":"Acuter-Optics","offers":[{"title":"Default Title","offer_id":56753027449163,"sku":"ACACLX40","price":1359.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0886\/1981\/1147\/files\/acuter_lumax_40ed_rifrattore_solare_telescopio.jpg?v=1773419535","url":"https:\/\/adriasky.it\/en\/products\/solar-refractor-acuter-luma-x-40-ed-h-alpha","provider":"Adriasky","version":"1.0","type":"link"}
