Contact Starizona for help choosing the right spacers for your setup.\u003c\/p\u003e\n\u003ch3\u003eStarizona C8 EdgeHD T-Adapter w\/Filter Holder Installation\u003c\/h3\u003e\n\u003cp\u003eCelestron's EdgeHD Schmidt-Cassegrain telescopes require a specific backfocus in order to give the best optical quality over a large field of view.\u003c\/p\u003e\n\u003cp\u003eA T-adapter is used to attach a DSLR or CCD camera to the telescope. This T-adapter offers the ability to mount a filter, such as a light pollution reduction filter. It can work for both f\/10 imaging, and imaging at f\/7 with Celestron's EdgeHD 0.7x Reducer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBackfocus\u003c\/strong\u003e Th:e nominal backfocus of the C8 EdgeHD at f\/10 is 133.35 mm. This is measured from the end of the male threads on the rear cell of the telescope to the imaging sensor in the camera.\u003c\/p\u003e\n\u003cp\u003eWith the f\/7 focal reducer in place, the nominal backfocus is 105 mm. The backfocus, or flange focal distance, of DSLR camera vary, but when a T-ring is used to adapt the bayonet to a female T-thread mount, the backfocus is standardized at 55 mm. So at f\/10, a T-adapter must be 133.35 – 55 = 78.35 mm long. At f\/7 it must be 105 – 55 = 50 mm long.\u003c\/p\u003e\n\u003cp\u003eIn the case of a CCD camera, the backfocus of the camera will generally be much shorter. In this case, and extra spacer is required between the T-adapter and camera, the length of which is equal to 55 mm minus the CCD backfocus. Normally this is simply a spacer with female T-threads on one end and male T-threads on the other, but could be different if the CCD camera has a different thread mount. Contact OPT if you need assistance choosing the correct spacer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsing the Starizona C8 EdgeHD T-Adapter w\/Filter Holder:\u003c\/strong\u003e There are two configurations for the T-adapter; one for f\/10 use and one for f\/7.\u003c\/p\u003e\n\u003cp\u003eFor use at f\/10, the T-adapter should be in the longer configuration with the spacer installed, as shown below. The T-ring should be threaded directly onto the filter holder. For use at f\/7, remove the spacer and thread the filter holder back on to the shorter configuration as shown below. The T-ring should be threaded directly onto the filter holder.\u003c\/p\u003e\n\u003cp\u003eIf using a CCD camera instead of a DSLR + T-ring, thread the required spacer onto the top of the filter holder, then thread the camera onto the spacer. The base ring can be loosened while the camera and T-adapter are installed on the telescope to allow rotation of the camera angle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstalling a Filter:\u003c\/strong\u003e The filter holder is split and the thinner top portion can be unthreaded. A standard 2-inch (48 mm) filter can then be threaded into the female threads on the inside of the top portion. Thread the top portion back onto the bottom part and the filter is now installed in the light path.\u003c\/p\u003e\n\u003cp\u003eCertain CCD cameras may be able to use 1.25-inch filters, and a step ring to convert the 2-inch filter thread to 1.25-inch is available made by Starizona. However, a 2-inch filter is recommended for DSLRs to avoid significant vignetting.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- split --\u003e\n\u003cul\u003e\n\u003cli\u003eT-Adapter with 2-inch (48 mm) Filter Holder\u003c\/li\u003e\n\u003cli\u003eConnect a DSLR with T-ring to your Celestron 8-inch EdgeHD telescope\u003c\/li\u003e\n\u003cli\u003eInstall a 2-inch filter into the optical path.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Starizona","offers":[{"title":"Default Title","offer_id":68343050993888,"sku":"xey1793397977355","price":69.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0811\/8334\/2816\/files\/starizona-t-adapter-with-filter-slider---edge-hd-8-inch_1.jpg?v=1793397990"},{"product_id":"zwo-m68-sensor-tilt-adapter-for-6200mcmm-pro-cameras-m68-oag","title":"ZWO M68 Sensor Tilt Adapter for 6200MC\/MM Pro Cameras \u0026 M68 OAG","description":"\u003cp\u003eThe 5 mm M68 sensor tilt adapter was independently developed by ZWO and specially made to match with the full-frame cooled ZWO ASI6200MM-Pro and ASI6200MC-Pro cameras.\u003c\/p\u003e\n\u003ch3\u003eUse it with a 2-inch EFW and M68 OAG\u003c\/h3\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1594\/4815\/files\/ZWO-M68-ADAPTER_ZWO-M68-Sensor-Tilt-Adapter-2.jpg?v=1588795624\u0026amp;width=700\" alt=\"ZWO M68 Sensor Tilt Adapter -for 6200MC and MM Pro Cameras-use\" style=\"float: left;\" width=\"219\" height=\"219\"\u003e\u003c\/p\u003e\n\u003cp\u003eYou are encouraged to use it with a ZWO 2-inch EFW and ZWO M68 OAG by mounting them on the M68-thread telescope side.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis new M68 sensor tilt adapter can be used to connect with the M68 thread telescope side.
