Celestron T-Adapter SCT camera adapter

Celestron T-Adapter SCT camera adapter

This metal-bodied T-adapter attaches a film or digital SLR camera to the rear mount threads of a Schmidt-Cassegrain telescope for primary focus photography. The telescope acts as a long telephoto lens for the camera, allowing you to photograph, for example, the Moon or distant terrestrial subjects. See also our other accessories for astronomical telescopes.

How to attach a camera to a telescope

Remove the lens from the camera and attach a T-ring suitable for your camera brand in its place; it will click into place just like the lens. Remove the diagonal mirror and the visual erker from the rear of the telescope, screw the T-adapter onto the rear socket’s threads and finally screw the T-ring, with the camera attached, onto the adapter. For longer deep-sky exposures, a separate guide telescope or off-axis guide, as well as an equatorial mount, are recommended.

Main features

• Screw directly onto the rear mount of the Schmidt-Cassegrain telescope.
• The focal length of a telescope determines the magnification; for example, an 8-inch SCT is equivalent to a lens with a focal length of approximately 2,000 mm.
• On the camera side, there is a T-thread to which a T-ring specific to the camera brand is attached (sold separately).
• Suitable for short-exposure photographs of the Moon and terrestrial subjects.
