Canon SLR to Celestron Ultima 100
There is only one approach. Celestron does not make a t-adapter (a tube threaded on the back for a t-ring) for the Ultima - no need for one since the eyepiece is already threaded for a t-ring. To attach your Canon, all you need is a t-ring for an EOS, such as the 93419.
To attach the t-ring, peel off the rubber eyeguard on the Ultima eyepiece until the threads are exposed. Do not remove the eyeguard by unthreading it from the eyepiece. The correct threads are directly under the rubber section and you must peel off the rubber to expose them. When the correct threads are exposed, thread on the t-ting, then attach the camera body.
