How to connect Canon 5d SLR camera and 80eq astronomical telescope together?

The so-called extension tube is actually not for "extension", but to serve as a false eyepiece. Insert into the telescope eyepiece hole. The adapter ring is used when the lens is connected to a SLR. Then just screw the threads on the "tube" and "ring" together. So as long as the extension tube is 1.25 inches and the adapter ring is Canon EF mount, it will be OK. This doesn't matter what model it is.
