Celestron Canon M-Mount T-Ring (#93407)

Connect your Canon M-series mirrorless camera to your telescope for prime-focus astrophotography.

If you’re using a Canon EOS M-mount mirrorless camera, this Celestron T-Ring is your essential first step into the world of astroimaging. Designed specifically for Canon’s compact mirrorless M-series bodies, this adapter lets you attach your camera securely to any T-thread-compatible telescope adapter—perfect for capturing high-quality images of the Moon, planets, and deep sky wonders.

Purpose-Built for Canon M-Series Mirrorless Cameras

Mounting the T-ring is quick and intuitive. Simply align the ring with your Canon M-mount camera body, twist to lock, and you're ready to connect to your telescope or spotting scope. The back of the ring provides standard M42 x 0.75 (T-thread) compatibility, allowing it to pair seamlessly with popular Celestron T-adapters and other industry-standard accessories.

Compatibility Note: This ring fits Canon EOS M-mount mirrorless cameras only. It does not work with Canon EF, EF-S, or RF-mount DSLRs and mirrorless bodies unless a separate Canon adapter is used to convert those mounts to M-mount.

Built to Last in the Field

Celestron's Canon M-Mount T-Ring is machined from durable aluminum and finished with a sleek black anodizing that resists wear in outdoor environments. The glare-threaded interior minimizes stray light for better contrast in long exposures, while the ribbed exterior provides a secure grip for attaching and detaching the ring, even when wearing gloves.

Whether you’re imaging wide nebula fields or dialing in crisp lunar detail, this T-ring ensures your camera sits rock-steady on the optical axis—just where it needs to be.
