Celestron 93407 Canon M Mount T Ring with 42mm Diameter Thread For Terrestrial and Celestial Imaging, Compatible EOS Mirrorless Cameras Adpaters, Black

ESSENTIAL ACCESSORY: A T-Ring is one of the first accessories you will need to take pictures through a telescope or spotting scope. 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. CAMERA COMPATIBILITY: T-Ring attaches to EOS M-mount Canon mirrorless camera bodies only. BODY: 42mm female diameter thread. 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. ATTACHMENT INSTRUCTIONS: 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 Sturdy bayonet flange locks for a secure fit.
