Supporting by Dr. Wei-Hao Wang, it is improved to passing more than 95% of the light from the main spectral lines from emission nebula, such as the predominant Hydrogen-Alpha line at 656.3nm, the Oxygen III line at 495.9 \u0026amp; 500.7nm, and the Hydrogen-Beta line at 486.1nm. It is coated by the use of the IBAD (Ion beam-assisted deposition) technology on Schott® B270 optical glass, working for higher durability and easily cleaning. Since light pollution and airglow are filtered out with the Astro filter, much more of the interesting wavelengths of the deep-sky object will be recorded in these longer exposures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"x-content-band-4\" class=\"x-content-band vc\"\u003e\n\u003cdiv class=\"x-column x-sm vc x-1-1\"\u003e\n\u003cdiv class=\"x-main full\"\u003e\n\u003carticle id=\"post-4602\" class=\"post-4602 page type-page status-publish hentry no-post-thumbnail\"\u003e\n\u003cdiv class=\"entry-content content\"\u003e\n\u003cdiv class=\"x-container max width wpb_row\"\u003e\n\u003cdiv class=\"x-column x-sm vc x-1-1\"\u003e\n\u003ch2 class=\"h-custom-headline h5\"\u003e\u003cspan\u003eSpecification\u003c\/span\u003e\u003c\/h2\u003e\n\u003chr class=\"x-hr\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable id=\"tablepress-37\" class=\"tablepress tablepress-id-37\"\u003e\n\u003ctbody class=\"row-hover\"\u003e\n\u003ctr class=\"row-1 odd\"\u003e\n\u003ctd class=\"column-1\"\u003eAvailable Size\u003c\/td\u003e\n\u003ctd class=\"column-2\"\u003e48mm Clip Filter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row-2 even\"\u003e\n\u003ctd class=\"column-1\"\u003eMaterial\u003c\/td\u003e\n\u003ctd class=\"column-2\"\u003eSCHOTT® B270 Optical Glass, Aluminum 6061 rim\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row-3 odd\"\u003e\n\u003ctd class=\"column-1\"\u003eThickness\u003c\/td\u003e\n\u003ctd class=\"column-2\"\u003e2mm Glass, 3.5mm Rim\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row-4 even\"\u003e\n\u003ctd class=\"column-1\"\u003eWater drop contact angle\u003c\/td\u003e\n\u003ctd class=\"column-2\"\u003e\u0026gt; 110°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row-5 odd\"\u003e\n\u003ctd class=\"column-1\"\u003eOrigin\u003c\/td\u003e\n\u003ctd class=\"column-2\"\u003eTaiwan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"row-6 even\"\u003e\n\u003ctd class=\"column-1\"\u003ePassed\u003c\/td\u003e\n\u003ctd class=\"column-2\"\u003eRoHS 2.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"x-content-band-8\" class=\"x-content-band vc\"\u003e\n\u003cdiv class=\"x-container max width wpb_row\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/article\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"William Optics","offers":[{"title":"Default Title","offer_id":32517159321680,"sku":"YF-STC-M48","price":312.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0224\/6770\/6960\/files\/william-optics-filter-william-optics-stc-ultra-layer-astro-multispectra-fiter-48mm-yf-stc-m48-42609475027163.webp?v=1726315863"},{"product_id":"yg-io-sg01h-rd","title":"William Optics High Latitude WO Vixen Style Base Mount -
