Celestron T-Adapter, EdgeHD 925/11/14)

48mm T-Adapter for EdgeHD 9.25”, 11”, and 14” Telescopes

Overview:
The 48mm 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 48mm 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 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.

Below, 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.

Features:
• 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
