Hi Carl ,
If you start from scratch with a low profile SCT female to male T thread adapter ,then off axis guider to female T -Thread ,to canon eos ring you should have plenty of room.The off axis guider comes with several T -thread extensions if needed.If my nex5 to T-thread adapter was not 40mm long and only about 10mm like your eos adapter I would have to use an extension tube to get the focal reducer at an adequate distance.I'm sure with the bits I have I could put my 350d in place of the nex5. Looking at your picture you seem to have a extension tube of similar dimensions to the off axis guider without its extension tubes.look at the off axis guider in my picture , it has none of the extension tubes in the image train.hope this helps .
Regards philip
