Whoa there. That seems to be a Hyperion Projection EP and thus should be suitable for imaging provided you have the infocus or outfocus necessary for the eyepiece to reach the focal point. The important question is does the Hyperion EP reach focus ok if you use it visually. If it does then the only issue should be the spacing to the camera sensor from the top of the Hyperion. Baader has a paper on their website on how to set up Hyperions. I used to have that EP and i know it works. The Canon requires 55mm of spacing between the top of the Hyperion to the sensor.
Now if the Hyperion does not work visually you may have a focal point problem.
You could do the "paper test" to establish where the scope focal point is (basically hold a piece of paper above the focuser tube, with the scope aimed at the Moon, move the paper in and out to see if you can find a focal point where the Moon's image appears sharp on the paper - that is your native focal point). If you cannot achieve that, then it is likely that the focal point is too far inward for the use of any T-Adaptor and extension tube. A projection eyepiece (like the Hyperion) might still be able to pick it up further down the focuser tube but if you see nothing racked fully inward then I would suggest you can't reach focus with either technique.
If your determined to do it, you could try moving the primary mirror up the tube towards the focuser (this will move the focal point further up the focuser tube) ; this can be done somewhat by simply letting out the mirror springs so that they push the mirror more towards the focuser, but there are limits to this travel of course. If you let the springs out to max travel and redo the test, it may allow you to achieve focus. Do not let the springs out so much that the mirror comes loose because you lose adjustment screw range. There are ways to move further, longer screws, longer springs, but you need to ask yourself is it worth the effort, as any visual use is likely to require constant extension tube use in the future if setup that way.
