Celestron T-Rings 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
Celestron T-Ring For 35mm Cameras, remove the diagonal and/or eyepiece from your
Celestron Telescope (some models require use of an eyepiece ¿ see your instruction manual). 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
Celestron Telescope or
Celestron 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. Check your camera¿s instruction manual for more detailed information.
