Celestron EdgeHD 8 T-adapter

Celestron EdgeHD 8 T-adapter

A sturdy metal T-adapter attaches an SLR or DSLR camera to the rear mount threads of a Schmidt-Cassegrain telescope for primary focus photography. The camera then functions as a large telephoto lens, with the magnification determined by the telescope’s focal length. For example, an 8-inch SCT telescope has a focal length of approximately 2000 mm, which is considerably greater than that of a standard 300 mm telephoto lens.

Mounting the camera on a telescope

Remove the lens from the camera and attach a T-ring specific to your camera brand in its place. Remove the diagonal mirror and the visual finder from the rear housing of the telescope, screw the T-adapter onto the threads of the rear housing, and finally screw the T-ring and the camera onto the adapter. For longer deep-sky exposures, a separate guide telescope or off-axis guider, as well as an equatorial mount, are recommended.
