Unleash the full potential of your full-frame DSLR on large EdgeHD optical tubes with the Celestron 48mm T-Adapter. Designed to replace the smaller standard 42mm adapters, the larger diameter provides a larger light path to the camera to maximize the available amount of light while reducing or eliminating vignetting around the corners of the sensors, which can occur when using the smaller adapter with full-frame sensor cameras. This larger adapter is ideal for 9.25", 11" and 4" EdgeHD OTAs, and requires the use of an optional 48mm camera-specific T-ring to work correctly. It will not offer any advantage to cameras and imagers with smaller APS-C sensors.

I bought this T-adapter to connect my Celestron .7x Reducer and ZWO ASI2600MC DUO camera & spacers to achieve a secure connection & back focus. It's wide enough inside that I can put a 2 filter drawer in there to avoid vignetting while doing Deep Space Imaging and taking advantage of all the great imaging features offered by the 11 EdgeHD OTA.

Is there a way to magnify like a Barlow attachment to this?
The Celestron 48mm T-Adapter for 9.25"/11"/14" EdgeHD OTAs (BH # CETA9251114) will not accommodate an adapter with a Barlow lens.
