Many ready made filters do stretch the filter material like a drumhead in order to make it look like a piece of glass – this absolutely destroys the image quality, rendering the film useless for high magnification work. AstroSolar must be mounted entirely stress free in order to perform like a high precision flat window. It sounds like a contradiction with traditional perception of quality, but AstroSolar must show slight ripples! With this specially designed mounting, the Baader AstroSolar Telescope Filter with Optical Density of 5.0 provides exceptional optical imagery.  In fact, a\u003c\/span\u003efter 15 years of offering AstroSolar film sheets as a DIY-product, this system of Baader Solar Filters™ is designed to retain the true optical quality of the diffraction-limited AstroSolar Safety Film, even used at high magnifications.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ccolgroup\u003e \u003ccol span=\"1\" width=\"250\"\u003e \u003c\/colgroup\u003e\n\u003ccaption\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFILTER SIZE\u003c\/td\u003e\n\u003ctd\u003e80 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMANUFACTURER\u003c\/td\u003e\n\u003ctd\u003eBaader Planetarium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU (#)\u003c\/td\u003e\n\u003ctd\u003e2459310\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUSAGE\u003c\/td\u003e\n\u003ctd\u003eVisual solar observation and imaging at high magnification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eASTROSOLAR FILM\u003c\/td\u003e\n\u003ctd\u003eAstroSolar Safety Film\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOPTICAL DENSITY\u003c\/td\u003e\n\u003ctd\u003e5.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eINNER DIAMETER \/ CLEAR APERTURE (MM)\u003c\/td\u003e\n\u003ctd\u003e80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOUTER DIAMETER\u003c\/td\u003e\n\u003ctd\u003e170\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFILTER MOUNTED?\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOUTER CLAMPINGRANGE (10MM BOLTS)\u003c\/td\u003e\n\u003ctd\u003e110 – 140\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eINNER CLAMPINGRANGE (10MM BOLTS)\u003c\/td\u003e\n\u003ctd\u003e130 – 160\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOUTER CLAMPINGRANGE (20MM BOLTS)\u003c\/td\u003e\n\u003ctd\u003e100 – 130\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eINNER CLAMPINGRANGE (20MM BOLTS)\u003c\/td\u003e\n\u003ctd\u003e140 – 170\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSOLAR WAVELENGHT\u003c\/td\u003e\n\u003ctd\u003eWhite light\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":33160539841,"sku":"BAA-ASTF-80","price":83.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/1_0d9680f3-369d-46a2-a164-4d89f719aa06.png?v=1776459027","url":"https:\/\/khanscope.com\/en-fr\/products\/baader-astrosolar-telescope-filter-80mm-od-5-0-astf-80","provider":"Khan Scope Centre","version":"1.0","type":"link"}
