T Mount Adapter Ring Canon FD

A T-Ring couples your 35mm camera body to a T-Adapter, off Axis 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 CCTS offers a full line of T-Rings.

To use a T-Ring, remove the diagonal and/or eyepiece from your 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 telescope or spotting scope with a Camera T-Adapter.
