Need a T ring for telescope prime imaging.

Looking for the correct T ring for MFT for a telescope. The scope im ordering will have the T ring threads built into the visual adapter so i don't believe i will need the normal spacer T adapter to get proper focusing. AFAIK the only thing i need is the T ring that screws onto the built in threads but im not sure which ring is needed.

FYI im looking to order the Celestron C90 and will be using a GX7 now, EM1 later for imaging. If no help here i will ask in AP forums. FYI Here's a video explaining how the threads are built in but he's using a Canon with T ring. Will the MFT version be the same size? I assumed it would have to be longer as our mount/sensor distance is shorter.
