Hi Luka,
I image with an ED80 and a DSLR.
I have T ring on the camera body, then attached an Orion field flattener on it (it will screw into the T ring)

The other end has a 2" filter thread (which I screwed on a Baader UHC-S filter

The whole kit then slides into the ED80 focuser unit (I upgraded to a Baader Click Lock like this

Hope that helps.
