The Celestron Large SCT/EdgeHD Adapter pairs with the Off-Axis Guider (sold separately) allowing you to use the full image circle created by a 9.25",11" or 14" SCT or EdgeHD telescope. It's made specifically for those with a larger camera such as the Canon 5D or 6D as the area of illumination is increased resulting in brighter imagery
The Celestron Large SCT/EdgeHD Adapter is machined out of black anodized aluminium for increased durability and precision. This lightweight adapter weighs only 132 grams and attaches to the large baffle lock nut thread on the rear of the telescope. The OAG adapter has a clear aperture of 62.7mm (2.47 inches) and consumes 16mm of back focus.
