With DSLR CCD chips getting larger, Celestron created the 48mm T-Adapter to reduce vignetting and provide a larger light path to your camera’s sensor, producing exceptional astrophotos.\u003c\/p\u003e \u003cp\u003eThe standard T-Adapter for EdgeHD 9.25\", 11\", and 14\" comes with a 42mm T-Thread for a 42mm T-Ring. This smaller 42mm T-Adapter truncates the light cone coming from the back of the EdgeHD optical tubes, which creates vignetting in the corners of full frame imaging sensors. The 48mm T-Adapter has a larger T-Thread opening, allowing the unhindered light to illuminate the entire sensor, optimizing your full-frame sensor’s capabilities.\u003c\/p\u003e \u003cp\u003eBelow, you will find the difference between the 42mm and the 48mm T-Rings to give you an idea of the space the 42mm and 48mm T-Threads on the T-Adapter will provide.\u003c\/p\u003e \u003cp style=\"text-align: left;\"\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1935\/4371\/files\/T-Ring_Comparison_grande.jpg?v=1520643428\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e \u003cp\u003eNote: The 48mm T-Adapter will not offer any advantage to imagers with smaller APS-C sensors.  For this, Celestron still recommends the 42mm T-Adapter (#93646) and 42mm T-Rings for your specific model of camera. T-Rings are sold separately. See our 42mm Nikon T-Ring or Canon eos T-Ring.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCelestron does not offer 48mm T-Rings,\u003c\/strong\u003e however, we do recommend the ones sold by Sky-Watcher USA.  They offer the most popular models for Canon, Nikon, and Sony cameras.\u003c\/p\u003e \u003cp\u003eThe chart below shows the relative illumination of the sensor in a 42mm and a 48mm T-Adapter. The X-axis is the distance from the center of the camera sensor.  The Y-Axis is the amount of light being received. As you can see, the 48mm receives more light than the 42mm T-Adapter and will reduce vignetting in your images.\u003c\/p\u003e \u003cp\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1935\/4371\/files\/Charts_Combined_grande.jpg?v=1520894693\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":44926736040015,"sku":"93622","price":74.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/2406\/7407\/files\/93622_48mm_T-Adapter_1.jpg?v=1776998909","url":"https:\/\/hobbytechsupply.com\/products\/48mm-t-adapter-for-edge-9-25-11-and-14","provider":"Hobby Tech Supply","version":"1.0","type":"link"}
