It is designed for eyepiece projection photography of the Moon and planets.\u003c\/p\u003e\n\u003cp\u003eThe principle consists of photographing the image formed by an eyepiece with a CCD camera or a DSLR without lens. The advantage of this technique is that very high magnification ratios can be obtained, ideal for objects such as planets or the Moon. However, the image will appear less constrasted, due to the large eyepiece-to-sensor distance required. Finally, the use of an excellent quality eyepiece is strongly recommended to avoid degrading the image obtained.\u003c\/p\u003e\n\u003cp\u003eThe Takahashi TCA-4 Camera Adapter is composed of 2 removable elements: an eyepiece holder and a variable extension tube.\u003c\/p\u003e\n\u003cp\u003eThe eyepiece holder is designed to hold the projection eyepiece. The input side is M43x0.75 threaded. The output side is an eyepiece adapter with a 31.75 mm female barrel. The variable extension tube is attached to the eyepiece holder by means of a 50.8 mm female barrel. The output side is a male T thread (M42x0.75) which accepts standard T rings. It has a sliding device that allows the draw of the mount to be varied and therefore the magnification ratio on the sensor to be varied.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eCHARACTERISTIC\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eTAKAHASHI TCA-4 CAMERA ADAPTER\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eItem number\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eTKA00210\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eMechanical interface (input)\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eM43x0.75 thread, male\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eMechanical interface (output)\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eM42x0.75 thread, male\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eLength\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003e110 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"text-align: center;\" data-mce-style=\"text-align: center;\"\u003e320 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eHalf-section schematic view\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cfigure\u003e\u003cimg src=\"https:\/\/takahashi-europe.com\/assets\/uploads\/AUTRE\/TKA00210_schema.png\" title=\"TKA00210_schema_EN.png\" data-pagespeed-url-hash=\"866020493\" data-mce-src=\"https:\/\/takahashi-europe.com\/assets\/uploads\/AUTRE\/TKA00210_schema.png?width=700\" onload=\"pagespeed.CriticalImages.checkImageForCriticality(this);\"\u003e\u003c\/figure\u003e\n\u003cp\u003eMechanical input, mechanical output and metal back distance of the Takahashi TCA-4 Camera Adapter\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTakahashi Camera adapter TCA-4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eManual \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003eTakahashi 5-Years Warranty\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Takahashi","offers":[{"title":"Default Title","offer_id":46987419058374,"sku":"wse1787937842303","price":172.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/4048\/3270\/files\/takahashi-camera-adapter-tca-4-tka00210_1.jpg?v=1787937847","url":"https:\/\/www.seaspraynest.shop\/products\/takahashi-camera-adapter-tca-4-tka00210","provider":"My Store","version":"1.0","type":"link"}
