This corrector produces improved sharpness and a 1\/3rd reduction in the size of the spot equaling the spot size of the E-180 at the edge producing a 44 mm diameter circle. The offset secondary insures better illumination of the image formed by the primary.\u003c\/p\u003e\n\u003cp\u003eThe ε-130D has a 5.9° field of view which is perfect for imaging wide field objects like comets and objects with extended nebulosity. With a speed of f\/3.3 and a focal length of 430mm the ε-130D will shorten exposure times, increase color saturation and will produce wide field high performance images.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAperture\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e130mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFocal Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e430mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFocal Ratio\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ef\/3.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOptical Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eModified Hyperbolic Newtonian\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTBD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLimiting Magnitude\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTBD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLight Gathering Power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTBD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTube Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e166mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTube Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e460mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTube Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.9kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMetal Back Distance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e56.2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eImage Circle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e44mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eEpsilon ε-130D OTA (mount, tripod, tube holder and finder sold separately)\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\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Takahashi-Telescope-Specifications.pdf?v=1669843819\" style=\"font-size: 0.875rem;\" target=\"_blank\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Takahashi-Telescope-Specifications.pdf?v=1669843819\" style=\"font-size: 0.875rem;\" target=\"_blank\"\u003eTakahashi Telescope Specifications\u003c\/a\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Takahashi-Adapter-Specifications.pdf?v=1669843817\" target=\"_blank\"\u003eTakahashi Adapter Specifications\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eSystem Charts\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/Takahashi-Epsilon-_-130D-System-Chart.pdf?v=1669845114\" target=\"_blank\"\u003eTakahashi Epsilon ε-130D System Chart\u003c\/a\u003e\u003c\/p\u003e","brand":"Takahashi","offers":[{"title":"Default Title","offer_id":43125800763621,"sku":"TAK-TEK13010","price":3598.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/takahashi-epsilon-e-130d-astrograph-f3-3-tek13010-astronomy-plus-1.jpg?v=1690486285","url":"https:\/\/istronomyplus.com\/products\/takahashi-epsilon-%ce%b5-130d-astrograph-f-3-3-tek13010","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
