Each tube has an M48x0.75 internal and external thread. The M48x0.75 thread is also known as a large T2 photographic thread or a 2.0-inch filter thread. It allows the use of both camera-specific bayonet adapters and color and nebula filters. Includes 5 different tubes measuring 30, 20, 15, 10, and 5 mm. The large clear inner diameter of 45.0 mm effectively prevents unwanted vignetting of the camera sensor. The outer diameter of the tubes measures exactly 50.65 mm, and therefore can also be attached directly to any eyepiece holder with a 2-inch diameter.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFEATURES\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eM48x0.75 extension tube set\u003c\/li\u003e\n\u003cli\u003eFive extension tubes: 30, 20, 15, 10, 5 mm\u003c\/li\u003e\n\u003cli\u003eUse with correctors and field flatteners\u003c\/li\u003e\n\u003cli\u003eAdjustment of camera-to-focal plane distance\u003c\/li\u003e\n\u003cli\u003eSuitable for camera-specific bayonet adapters\u003c\/li\u003e\n\u003cli\u003eAlso suitable for 2.0-inch color and nebula filters\u003c\/li\u003e\n\u003cli\u003eM48x0.75 mm internal and external thread (large T2 thread)\u003c\/li\u003e\n\u003cli\u003eLarge clear inner diameter of 45.0 mm\u003c\/li\u003e\n\u003cli\u003eOuter diameter measures 50.65 mm (2 inches)\u003c\/li\u003e\n\u003cli\u003eMatte black anodized aluminum\u003c\/li\u003e\n\u003cli\u003eTotal weight 85 grams\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cb\u003eINCLUDES\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eM48x0.75 extension tube, 30 mm long\u003c\/li\u003e\n\u003cli\u003eM48x0.75 extension tube, 20 mm long\u003c\/li\u003e\n\u003cli\u003eM48x0.75 extension tube, 15 mm long\u003c\/li\u003e\n\u003cli\u003eM48x0.75 extension tube, 10 mm long\u003c\/li\u003e\n\u003cli\u003eM48x0.75 extension tube, 5 mm long\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":52791598809431,"sku":"510381","price":71.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/0510381_M_1.jpg?v=1770989696","url":"https:\/\/astrotelescopios.com\/en-us\/products\/kit-de-casquillos-de-prolongacion-explore-scientific-m48x0-75-5-piezas-30-20-15-10-y-5-mm","provider":"Astro Telescopios","version":"1.0","type":"link"}
