A T-Ring couples your 35mm camera body to a T-Adapter, Radial Guider or Tele-Extender. This accessory is required if you want to do any type of photography through a telescope or spotting scope. Each camera manufacturer has a different mount, which requires a specific T-Ring, so Celestron offers a full line of T-Rings.
To use a T-Ring, remove the diagonal and/or eyepiece from your telescope. Then you need only remove your normal camera lens, attach the proper T-Ring for your camera, and mount the combination to the rear cell of your telescope or spotting scope with a Celestron T-Adapter.
If you own an older SLR camera with a thread mount, it will probably accept the Pentax Universal Thread Mount T-Ring. If you have a new camera with a bayonet mount not listed above (Ricoh, Cosina, etc.), it most likely accepts the Pentax K-Universal Bayonet Mount T-Ring.
