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:

 1. look at Jupiter with 25mm eyepiece in telescope: clear and focused image
 2. look at Jupiter with 6mm eyepiece in telescope: clear and focused zoomed image
 3. look at Jupiter with camera and no eyepiece inside the t-adaptor, in telescope: clear and focused image but small.
 4. 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?

The focal length may be too short.  The T-mount does not guarantee everything will work.  It only allows you to mate them together.

The set up I have REPLACES the eyepiece rather than attaches to it. It was originally bought in an FD mount but I was able to buy an EF adapter for it but I just have a cheap telescope.

I just visited a popular online photo/video store, B&H.  I assume that you are using the Celestron NexStar 5 SE.  I am not certain if you have the correct camera adapter.  B&H currently lists a different model number, 93635-A, camera adapter.  The image of the adapter posted at B&H shows different marking on the barrel than yours.

 

" First, remove the eyepiece. Next, attach the SLR camera adapter where the eyepiece would normally be attached to the telescope, and screw in a t-mount adapter to the opposite end of the SLR camera adapter. Now you can attach your camera to the t-mount and you are ready to begin taking pictures! " 

 

The above quote is from the product description of the adapter.  The camera adapter is used in place of an eyepiece, not in conjunction with one.  I would advise consulting Celestron, or even B&H, for better advice and guidance.

That's how mine works. The camera replaces the eye piece.

That's good to know.  The OP has a generic camera adapter, which mounts onto an eyepiece, instead of the one made specifically for his telescope model.  Maybe an extension on the T-adapter could "fix" his generic one.  Who can say?  But, the model specific adapter costs nearly the same as an extension.
