A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. Celestron offer T-rings for Nikon DSLR or Canon EOS DSLR camera bodies. You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adaptor to turn your telescope or spotting scope into a large telephoto lens.

To use a T-Ring, remove the lens from your camera, and attach the T-Ring in its place, just as you would if you were mounting a lens. The telescope side of the T-Ring has threads that will accept a variety of camera adaptors, including the Celestron T-Adaptor or Tele-Extender. The adaptor you choose depends on the type of photography you wish to do.

  • The #93633-A T-Adaptor is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads.
  • If you have a refractor, the Universal T-Adaptor (#93625), with its 1-1/4” barrel insert, is available.
  • There are also special T-Adaptors for the EdgeHD optical system: one for the 8-inch EdgeHD (#93644) and one for the 9.25, 11, and 14-inch EdgeHD (#93646).

Prime focus photography without an additional adaptor is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. However if you need extra magnification beyond that which your Schmidt-Cassegrain telescope provides, a Tele-Extender (#93643) will allow you to insert an eyepiece inside the barrel before attaching it to the telescope. A Tele-Extender is used most often for high power images of the Moon and the planets.
