By using ED glass in the corrector, a spot image within 3 μm has been achieved at the periphery of a full frame imaging sensor. The E-160ED combines the ease of handling of the E-130D  with the high performance of the E-180ED.\u003c\/p\u003e\n\u003cp\u003eThe eccentric oblique mirror and the spider vane design are used to suppress the scatter of light similar to the current epsilon models. The method of holding the primary mirror uses the same system as E-180ED. The optical axis adjustment screw of the primary mirror has a structure in which push screws are arranged on both sides of the pull screw. The central cover can be removed to allow for rapid temperature acclimation.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"527\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"210\"\u003eOptical Design\u003c\/td\u003e\n\u003ctd width=\"317\"\u003eHyperbolic Newtonian\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEffective aperture\u003c\/td\u003e\n\u003ctd\u003e160 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOblique mirror minor diameter\u003c\/td\u003e\n\u003ctd\u003e63 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorrection lens\u003c\/td\u003e\n\u003ctd\u003e2 elements in 2 groups (1 of which is ED glass)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal length\u003c\/td\u003e\n\u003ctd\u003e530 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal ratio\u003c\/td\u003e\n\u003ctd\u003e3.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImage circle\u003c\/td\u003e\n\u003ctd\u003eφ44 mm (angle of view: 4.8°)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLens barrel diameter\u003c\/td\u003e\n\u003ctd\u003e204 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube length\u003c\/td\u003e\n\u003ctd\u003e580 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMass\u003c\/td\u003e\n\u003ctd\u003e6.9 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eViewfinder\u003c\/td\u003e\n\u003ctd\u003e6×30 or 7×50, Sold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eEpsilon E-160ED\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eManual \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\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","brand":"Takahashi","offers":[{"title":"Default Title","offer_id":43125836873957,"sku":"TAK-TEK16010","price":5530.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/takahashi-epilson-e-160ed-tek16010-astronomy-plus-1.jpg?v=1690487248","url":"https:\/\/istronomyplus.com\/products\/takahashi-epilson-e-160ed-tek16010","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
