Constructed from black aluminum, this adapter adds only 50g to your optical train and offers a variable extension of up to 30mm (1.18 inches) to achieve precise focus with different camera sensors. With a total length of 50mm (1.97 inches), it also features a female 2''24TPI thread, allowing for additional accessory configurations.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDirect SCT to T-Ring Adaptation at Just 50g\u003c\/h3\u003e\n\u003cp\u003eThis adapter is engineered for one primary purpose: to create a rigid, secure link between your SCT and your imaging camera. The male SCT threads attach directly to your telescope's rear cell, while the female M42x0.75 threads accept a standard T-ring for your DSLR or a nosepiece on your dedicated astronomy camera. Made of aluminum, the entire unit weighs only 50g, minimizing any balance or focuser strain issues on your setup.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e30mm of Variable Extension for Precise Focus\u003c\/h3\u003e\n\u003cp\u003eAchieving perfect focus is critical, and the SV167's variable length is its key feature. It provides 30mm of extension travel, allowing you to precisely set the distance between the telescope and your camera's sensor. This adjustability is essential for accommodating the different back-focus requirements of various DSLRs, mirrorless cameras, and dedicated CMOS\/CCD imagers, ensuring you can reach a sharp, stable focus without needing a collection of fixed-length extension tubes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I use the SVBONY SV167 adapter with my DSLR?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eFirst, you need a T-ring specific to your camera brand (e.g., Canon EOS, Nikon F). Screw the T-ring onto the M42x0.75 female threads of the SV167 adapter. Then, screw the adapter's larger SCT-threaded end onto the rear cell of your Schmidt-Cassegrain telescope. Finally, attach your camera body to the T-ring.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat does the 30mm extension travel on the SV167 adapter allow me to do?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe \u003cstrong\u003e30mm of travel\u003c\/strong\u003e allows you to finely adjust the camera-to-telescope distance. This is crucial for reaching sharp focus, as different cameras have sensors at different depths. It eliminates the need for stacking multiple fixed extension tubes, giving you a single, adjustable solution for focusing your camera.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the SVBONY SV167 help my mirrorless camera reach focus on a Celestron 8\" SCT for imaging the Orion Nebula (M42)?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this is an ideal application. SCTs often require significant back focus, especially with mirrorless cameras that have short flange distances. The SV167's 30mm of adjustable extension provides the range needed to push the camera sensor out to the SCT's focal plane, allowing you to capture deep-sky objects like the Orion Nebula (M42).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat are the different threads on the SVBONY SV167 adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe SVBONY SV167 has three distinct threads:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale SCT Thread:\u003c\/strong\u003e This is the larger thread that connects to the back of your Schmidt-Cassegrain telescope.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale M42x0.75 Thread:\u003c\/strong\u003e This is the standard \"T-thread\" for connecting camera T-rings and other astronomy accessories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale 2\" 24TPI Thread:\u003c\/strong\u003e This internal thread can be used to attach 2\" filters or other specialized accessories inside the light path.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs the SVBONY SV167 strong enough for a heavy camera setup?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe adapter is made of aluminum and weighs only 50g. It is perfectly suitable for DSLRs, mirrorless cameras, and most small-to-medium format dedicated astronomy cameras. For extremely heavy imaging trains (e.g., a large format camera plus a heavy filter wheel and off-axis guider), you may want to consider a more heavy-duty, threaded connection system to prevent any potential flexure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eI'm trying to image Jupiter with my ZWO camera and an 11\" SCT.

If you cannot achieve focus because the sensor is too close to the telescope, the SVBONY SV167's 30mm extension will help push the camera outward to the correct focal point. This is a common issue when using Barlow lenses or ADC units in a planetary imaging train, and this adapter provides the necessary spacing to solve it.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSVBONY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTelescope Connection\u003c\/td\u003e\n\u003ctd\u003eMale SCT Thread\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccessory Connection\u003c\/td\u003e\n\u003ctd\u003eFemale 2''24TPI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCamera Connection\u003c\/td\u003e\n\u003ctd\u003eFemale M42x0.75 T-Thread\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExtension Travel\u003c\/td\u003e\n\u003ctd\u003e1.18inch \/ 30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall Length\u003c\/td\u003e\n\u003ctd\u003e1.97inch \/ 50mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e50g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBright Black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eSVBONY SV167 Camera Adapter\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/svbony-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eSVBONY Warranty Policy\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SVBONY","offers":[{"title":"Default Title","offer_id":52861245423901,"sku":"SV-W9127A","price":19.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/SVBONY-SV167-camera-adapter-for-SCT-prime-focus-photography-1_e7e1698c-959a-4fc6-ba72-7c9ce6ebfad2.jpg?v=1788660550","url":"https:\/\/davidastro.com\/fr-us\/products\/svbony-sv167-camera-adapter-for-sct-prime-focus-photography","provider":"David Astro","version":"1.0","type":"link"}
