93419 T-Ring for Canon EOS Camera by Celestron

A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. If you have a Canon EOS camera body, the Celestron EOS T-Ring is the one for you.

To use the Canon EOS 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 adapters, including the Celestron T-Adapter or Tele-Extender. The adapter you choose depends on the type of photography you wish to do.

You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adapter to turn your telescope or spotting scope into a large telephoto lens. The #93633-A T-Adapter is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads. If you have a refractor, the Universal T-Adapter (#93625), with its 1-1/4" barrel insert, is available. There are also special T-Adapters 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 is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

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.

• This Celestron T-Ring attaches to Canon EOS DSLR and SLR camera bodies.
• Sturdy bayonet flange locks in place just like a lens, providing secure contact.
• Attaches to a variety of camera adapters and accessories via standard T-threads.
• This T-ring fits EOS model cameras only. It will not work with other Canon camera bodies.
