{"product_id":"t2-extension-tube-set-5-extensions","title":"M42 Extension Ring Set (5 Extensions)","description":"Set of 5 extension tubes with T2 thread on both sides for exact distances and a secure hold of cameras used for astrophotography. This set also comes with a SC to T2 thread adapter.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eIn astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75), which is the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not the correct focus distance. This is especially important when using correctors, reducers or flatteners in the image train. This extension tube set, which consists of 5mm, 7.5mm, 10mm, 15mm and 30mm tubes, will allow you to obtain almost any distance using various combinations. Each tube has a T2 interior thread on one side and a T2 exterior thread on the other side.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eMost telescopes either include a T2 thread adapter, or the eyepiece can be used with a simple T2 thread adapter with a 2\" plug-in.\u003cbr data-mce-fragment=\"1\"\u003eHowever, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or Ritchey Chrétien telescopes may use a so-called SC thread. To allow you to use this extension tube set with these telescopes, the set also includes an SC to T2 thread adapter.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003cul\u003e\n\u003cli\u003e5 T2 tubes with lengths from 5 mm to 30 mm\u003c\/li\u003e\n\u003cli\u003eCombination of tubes allows you to obtain distances of 5 mm to 67.5 mm\u003c\/li\u003e\n\u003cli\u003eFor exact camera distances in astrophotography\u003c\/li\u003e\n\u003c\/ul\u003e\nWhats included:\u003cbr data-mce-fragment=\"1\"\u003e\n\u003col\u003e\n\u003cli\u003e5 x T2 extension tubes (5\/7.5\/10\/15\/30 mm)\u003c\/li\u003e\n\u003cli\u003e1 x SC to T2 thread adapter\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bresser","offers":[{"title":"Default Title","offer_id":40682012868803,"sku":"4940160","price":30.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/BresserT2AstrocamExtensionSet.jpg?v=1631708469","url":"https:\/\/www.horizonastronomy.ie\/en-dk\/products\/t2-extension-tube-set-5-extensions","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
