Use the 4.3X telecentric barlow by unscrewing the silver snout from the Combo Quark and screwing on the barlow.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFor refractors from F\/5 to F\/9 you have a choice of the 2.8X or 4.3X telecentric barlows. The 4.3X barlow will show full disk with approximately 480mm focal lengths or shorter. The filter performs better with a narrower bandpass with the 4.3X barlow, prioritizing surface contrast at the expense of a dimmer image as compared to the 2.8X barlow. We encourage experimentation to determine which setup best meets your goals.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003eTechnical Specifications\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003ctable cellspacing=\"0\" border=\"0\"\u003e\n\u003ccolgroup span=\"2\" width=\"193\"\u003e\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd height=\"17\" align=\"center\"\u003eMagnification\u003c\/td\u003e\n\u003ctd align=\"center\"\u003e4.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd height=\"17\" align=\"center\"\u003eFL where Sun Disk is Full\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eFrom 480mm and shorter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"text-align: center;\"\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eIn the Box\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e4.3X Telecentric Barlow\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDust caps\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/istronomyplus.com\/pages\/daystar-filters-warranty\" rel=\"noopener\" target=\"_blank\"\u003eDaystar 5-Years Warranty\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Daystar-Quark-Flyer.pdf?v=1668026525\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eDaystar Quark Flyer\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Daystar-Combo-Quark-Manual.pdf?v=1668028351\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eDaystar Combo Quark Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"Daystar","offers":[{"title":"Default Title","offer_id":46731402117349,"sku":"DAY-CC43B","price":419.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/DAYSTAR4_3XBarlow1.webp?v=1746038254","url":"https:\/\/istronomyplus.com\/products\/daystar-combo-quark-4-3x-telecentric-barlow-b4-3","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
