Besides, it can improve the star shapes. The diameter of stars in the center of the field can be limited within 10um.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"pdp-content-description rte active\" data-pdp-tab-content=\"description\"\u003e\n\u003ch3\u003eTechnical Specifications\u003cbr\u003e\n\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pdp-content-description rte active\" data-pdp-tab-content=\"description\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"pdp-content-description rte active\" data-pdp-tab-content=\"description\"\u003e\n\u003ctable align=\"center\" cellspacing=\"0\" width=\"84.20%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"3\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e150-600mm, f\/3-3\/6 parabolic reflectors\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eReduction factor\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e0.95×\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eImage circle\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e44mm(maximum), 28mm(optimal)\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eLens\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003etriplet structure\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eOuter diameter\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e50.8mm(2\")\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eBack focus\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e56mm(starting from the field-stop-ring to the focal plane)\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eLength\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e79.7mm\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eCoating\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003efull-surface multi-layer coatings\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cstrong\u003e0.22kg\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSharpStar 2\" 0.95× Coma Corrector \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\u003c\/ul\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eSharpStar Warranty\u003c\/p\u003e\n\u003c\/div\u003e","brand":"SharpStar","offers":[{"title":"Default Title","offer_id":46310309953765,"sku":"SS-095x-COMA","price":427.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Sharpstar-2-095x-Coma-Corrector.webp?v=1730930812","url":"https:\/\/istronomyplus.com\/products\/sharpstar-2-0-95-coma-corrector-095x-coma","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
