One of the first items you'll need to use a telescope or spotting scope to take photos is a T-Ring. The Celestron EOS M-Mount T-Ring is the best option if you own a Canon EOS mirrorless camera body.

How to Use

Put the M-Mount T-Ring on your Canon mirrorless camera to use this T-Ring. Align the T-Ring with your camera's lens mount, much like you would when replacing a lens. Turn it until you hear a click, then push it in. A strong bayonet flange on the T-Ring locks for a tight fit. You can connect your telescope once the T-Ring has been connected to your camera. The threads on the telescope side of the T-Ring are compatible with a number of camera adapters, including the Celestron T-Adapter. The type of photography you want to do will determine the adapter you select.


The 42mm T-ring for the Canon M-Mount is made of black anodized machined aluminium. For the maximum contrast, the inside surfaces are blackened and glare-threaded. A ribbed surface on the T-Ring provides a firm grip for threading or unthreading. M42 x 0.75 (T-Thread) camera adapters are compatible with the Canon M-Mount 42mm T-Ring.

Terrestrial and Celestial imaging

To transform your telescope or spotting scope into a powerful telephoto lens, combine your T-Ring with a Celestron T-Adapter. Use these adapters with your M-Mount T-Ring, depending on the optics you have:
