It extends beyond the telescope's aperture, slowing heat loss and shielding the optics from moisture, stray light, and glare. Attaching the Dew Shield to your optical tube is easy thanks to the Velcro attachment points.\u003c\/p\u003e\n\u003cp\u003eThe furthest interior section of the shield is flocked with felt, a material chosen for its excellent light-absorbing properties. This dark, non-reflective felt lining minimizes internal reflections, improving contrast and preserving image quality. In addition to enhancing optical performance, the felt also helps absorb excess moisture, further reducing the risk of dew formation on the telescope’s lens or corrector plate. \u003c\/p\u003e\n\u003cp\u003eA strip of added faux-leather padding is incorporated into the design to protect the telescope tube’s finish, preventing scratches and ensuring a secure, non-abrasive fit.\u003c\/p\u003e\n\u003cp\u003eA properly designed dew shield is a simple yet effective way to optimize viewing and imaging conditions, particularly in humid or light-polluted environments.\u003c\/p\u003e\n\u003cp\u003eFits standard 5'' tubes (130mm), MAK (127mm) and SCT Telescopes.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable cellspacing=\"0\" border=\"0\"\u003e\n\u003ccolgroup width=\"85\" span=\"2\"\u003e\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd height=\"17\" align=\"center\"\u003eHeight\u003c\/td\u003e\n\u003ctd align=\"center\"\u003e570 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"17\" align=\"center\"\u003eLength\u003c\/td\u003e\n\u003ctd align=\"center\"\u003e230 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"17\" align=\"center\"\u003eFits\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eStandard 5” SCT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e5'' Felt-Lined Dew Shield\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Astronomy Plus","offers":[{"title":"Default Title","offer_id":51079445053687,"sku":"any1787937828026","price":13.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/0577\/9447\/files\/astronomy-plus-5-felt-lined-dew-shield-ta589_1.jpg?v=1787937838","url":"https:\/\/www.thegracefulroom.shop\/products\/astronomy-plus-5-felt-lined-dew-shield-ta589","provider":"My Store","version":"1.0","type":"link"}
