Yes, I am using a T-adapter. Strange thing, though, that the image is sharp on the DSLR LCD display but less after capture. I am using a remote shutter controller to avoid shaking.

Hi all, What is the best way to hook up a DSLR (Canon Rebel T3i) with the Celestron Nexstar 4SE? I've tried some options (Celestron MAK extension, etc...) but my pictures are not sharp. Obviously, I have to deal with some backfocusing issues but so far I could not find the right combination of visual back, extension tubes, etc... to get sharp pictures. Any suggestion? Thanks in advance.
