This change is a real challenge for conventional refractors, most of whose lenses have been designed to best cover the APS-C format. Although the Takahashi FSQ-85EDX is designed as a Petzval quadruplet, the full-format sensor coverage was not perfect and the edge of the field suffered from a slight astigmatism typical of this optical system. Takahashi offers a dedicated corrector to correct this defect and thus offer results close to those of the FSQ-106ED. The field is perfectly corrected on a diameter of 44 mm. The flattener causes the focal length of the FSQ-85EDX to be slightly increased (by a factor of 1.01x) from 450 mm (F\/5.3) to 455 mm (F\/5.4).\u003cbr\u003e\u003cbr\u003eThe flattener has a M72x1 male thread on the telescope side and a M54x0.75 female thread on the camera side. The required backfocus behind the corrector is 56.2 mm. A female thread at the front accepts filters with an M58 thread.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eTakahashi FL1.01X (FSQ-85EDX) field corrector\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eCHARACTERISTIC\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eTAKAHASHI FL1.01X (FSQ-85EDX) FIELD CORRECTOR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eImage circle diameter\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e44 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eMetal back distance\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e56.2 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eInput mechanical interface\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eM72x1 thread, male\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eOutput mechanical interface\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003eM54x075 thread, female\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eBackfocus\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e36 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eDiameter\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e80 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eTotal length\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e41 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\"\u003e200 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/takahashi-europe.com\/assets\/uploads\/AUTRE\/TKA37582_schema_EN.png\"\u003e\u003c\/p\u003e\n\u003cp\u003eDiagram of the focal point position and threads of the Takahashi FL1.01X field corrector\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/takahashi-europe.com\/assets\/uploads\/SPOT-DIAGRAMS\/FSQ-85EDX_FL101X_spots.png\"\u003e\u003c\/p\u003e\n\u003cp\u003eSpot-diagram of Takahashi FSQ-85EDX refractor with FL1.01X field corrector\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTakahashi 1.01x Flattener for FSQ-85ED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eManual \u0026amp; Warranty \u003c\/h3\u003e\n\u003cdiv id=\"shopify-section-template--16185084641509__description\" class=\"shopify-section\"\u003e\n\u003csection data-section-id=\"template--16185084641509__description\" data-section-type=\"tabbed\" data-url=\"\/\/takahashiamerica.com\/cdn\/shop\/t\/3\/assets\/script.tabbed.js?v=83467205078527531921656105673\" data-carousel-type=\"section\" class=\"container clearfix loaded ignore\"\u003e\n\u003cdiv class=\"nine center text-left bottompad clearfix\"\u003e\n\u003cdiv id=\"description\" class=\"product-desc tab-body tab-body-content tab-body-id-template--16185084641509__description\" role=\"tabpanel\" aria-labelledby=\"tab-description\" tabindex=\"0\" data-mce-tabindex=\"0\"\u003e\n\u003cp class=\"tabindex\"\u003e\u003ca href=\"https:\/\/takahashiamerica.com\/pages\/warranty-service?_pos=1\u0026amp;_psq=warranty\u0026amp;_ss=e\u0026amp;_v=1.0\" data-mce-href=\"https:\/\/takahashiamerica.com\/pages\/warranty-service?_pos=1\u0026amp;_psq=warranty\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003eTakahashi 5-Years Warranty\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Takahashi","offers":[{"title":"Default Title","offer_id":44154309279973,"sku":"TAK-TKA37582","price":369.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/takahashi-1-01x-flattener-for-fsq-85ed-tka37582-astronomy-plus-1.jpg?v=1690492276","url":"https:\/\/istronomyplus.com\/products\/takahashi-1-01x-flattener-for-fsq-85ed-tka37582","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
