Celestron and Meade Schmidt-Cassegrain scopes have a short, flanged tube
which screws onto the back of the scope with a threaded locking ring.
On the other end of the tube is a male T2 thread for a standard T2
adapter ring. They look like this:

For a Newtonian scope with 1-1/4" or 2" focusing tube you need one of
these <http://www.telescopeadapters.com/> But note the warning on use
of T-rings with 2" focusing tubes. The ID of the T-ring is smaller than
the 2" tube so may serve as a vignetter.
