  • T-Ring attaches to M-mount Canon mirrorless camera bodies
  • Works with Celestron T-Adapters
  • 42mm female diameter thread
  • Sturdy bayonet flange locks for a secure fit


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.

Description

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 0.50 (T-Thread) camera adapters.

Christopher ★★★★★

The bayonet flange locks on with a reassuring click, and the fit inside my camera body is perfectly snug—no wobble at all. Finally got my mirrorless rig paired with the telescope for some clean moon shots.

Timothy H. ★★★★★

Finally got this attached to my mirrorless body and the bayonet flange locks on tight with no wobble at all. It paired perfectly with my Celestron adapter for some crisp moon shots last night.

Michael J. ★★★★★

The 42mm thread threaded smoothly onto my Celestron adapter without any play or wobble. It feels solidly built and I'm happy the bayonet flange gives me a nice secure lock to the camera body.
