A T-Ring is one of the first accessories you will need to take pictures through a telescope or spotting scope. If you have a Canon EOS mirrorless camera body, the Celestron EOS M-Mount T-Ring is the one for you.
How to Use
To use this T-Ring, place the M-Mount T-Ring on your Canon mirrorless camera. Just like changing a lens, line up the T-Ring to your camera’s lens mount. Push it in and turn until you hear a click. The T-Ring has a sturdy bayonet flange that locks for a secure fit.
Once you attach the T-Ring to your camera, you’re ready to connect your telescope. The telescope side of the T-Ring has threads that accept a variety of camera adapters, including the Celestron T-Adapter. The adapter you choose depends on the type of photography you wish to do.
Body
The Canon M-Mount 42mm T-ring is machined aluminum black anodized. The internal surfaces are blackened and glare-threaded to provide the highest contrast. The T-Ring has a ribbed surface for a secure grip while threading/unthreading. The Canon M-Mount 42mm T-Ring is compatible with M42 x 0.75 (T-Thread) camera adapters.
Terrestrial and Celestial Imaging
Pair your T-Ring with a Celestron T-Adapter to turn your telescope or spotting scope into a large telephoto lens.
Depending on the optics you own, you may need to pair your M-Mount T-Ring with one of the following
- Universal T-adapter 1.25"
- Universal Barlow and T-Adapter - 1.25"
- T-Adapter for Schmidt-Cassegrain Telescopes
This T-Ring fits EOS M-mount mirrorless cameras only. It will not work with other Canon camera bodies like the EOS RF-mount or EOS EF-mount model cameras without adding a Canon adapter to convert those cameras to M-mount.
