Celestron Canon M-Mount T-Ring and T-Adapter Bundle

Celestron Canon M-Mount T-RingA 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.Celestron T-Adapter with SCT 5, 6, 8 with 9.25, 11, 14, Black (93633-A)This sturdy metal T-Adapter is the accessory of choice if you’d like to attach an SLR or DSLR camera to the rear cell threads of a Schmidt-Cassegrain telescope for prime focus photography. To get started, you’ll need the appropriate T-Ring for your camera body (#93402 for Nikon & #93419 for Canon EOS). Remove the lens from your camera and attach the T-ring in its place. Since the T-ring is camera-brand specific, it will snap right on just like a lens. Next, remove the diagonal and visual back from the rear cell of your telescope. Screw the Celestron T-Adapter onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adapter. That’s all there is to it. The camera is now using your telescope as a giant telephoto lens. The magnification will depend on the telescope’s focal length. For instance, a 300mm camera lens is considered to be pretty powerful, right? Well, if you are using an 8” SCT at prime focus, you’ve got yourself a 2000mm lens with a lot of light-gathering capability! Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. If you want to do longer exposures of deep sky objects with this method, we suggest using a separate guidescope or off-axis guider and an equatorial mount.
