48mm Wide T-Adapter EdgeHD 925, 11, 14

• Attaches directly to the rear cell of the larger Edge optical tubes
• Produces better illumination for today's larger full-frame imaging sensors, all the way to the corners
• Reduces vignetting–darkening around the edges of the image sensor–by providing unobstructed light to the camera

The 48 mm T-Adapter is the accessory of choice if you’d like to attach your full frame DSLR or astronomical camera to a Celestron EdgeHD optical tube. With DSLR CCD chips getting larger, Celestron created the 48 mm T-Adapter to reduce vignetting and provide a larger light path to your camera’s sensor, producing exceptional astrophotos.

The standard T-Adapter for EdgeHD 9,25", 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 sensor’s 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.

Note: a 48mm T-ring is required to mount a DSLR camera with this adapter. A standard 42mm T-ring will not fit.
