How do I get focussed images with my T-adaptor and 6mm eyepeice? I have a Celestron 5se + canon 650d. They are mated with the celestron t-ring and the 93625 t-adaptor. 
I want to take magnified photos of planets with the camera. But if I add an eyepiece to the t-adaptor, everything gets blur.
Here are some scenarios that highlight the problem:

look at Jupiter with 25mm eyepiece in telescope: clear and focused image
look at Jupiter with 6mm eyepiece in telescope: clear and focused zoomed image
look at Jupiter with camera and no eyepiece inside the t-adaptor, in telescope: clear and focused image but small.
look at Jupiter with camera and 6mm eyepiece inside the t-adaptor, in telescope: large unfocused ball

I dont know how to solve this.
Clearly, the 93625 t-adaptor was made to accept an eyepiece and lock it with the thumbscrew, but why does it not result in focused images?
Using the eyepiece, and no camera lens, is a very different configuration to the camera+tube+scope (case 3).  The configuration you're after is "Eyepiece projection".

I don't know exactly what you have available, but I believe you will need to fit a T-threaded extension tube to the external thread on your T-adapter. Then fit the camera onto that.

Note - before you go out and buy a new extension you can probably do a hand-held test of this by the following:


Attach the adapter to the scope, with a low-power eyepiece in the adapter (low power makes the test easier to see.)
Point the scope at anything distant (you can do this in daylight, but NOT at the sun of course!)
Now hold the camera, by hand, a few inches behind the
eyepiece+adapter. Perhaps you can use a cardboard tube to keep the stray light out.
See if you can adjust the scope's focus, and the camera position, to get a sharp image.


If this worked, then you can get a T-threaded extension tube to go on the back of your current adapter, to hold the camera in position.
