Celestron 48mm T-Adapter for EdgeHD 9.25in11in14in

Celestron 48mm T-Adapter for EdgeHD 9.25in11in14in. With DSLR CCD chips getting larger Celestron created the 48 mm T-Adapter to reduce vignetting and provide a larger light path to your cameras sensor producing exceptional astrophotos. The standard T-Adapter for EdgeHD 925" 11" and 14" comes with a 42 mm T-Thread for a 42 mm T-Ring. This smaller 42 mm 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 48 mm T-Adapter has a larger T-Thread opening allowing the unhindered light to illuminate the entire sensor optimizing your full-frame sensors capabilities. Below you will find the difference between the 42 mm and the 48 mm T-Rings to give you an idea of the space the 42 mm and 48 mm T-Threads on the T-Adapter will provide.
