I use one on a qhy9 mono with starlight wheel and I have the long extension plus the short extension tube in between the QHY5 and the OAG, I removed that thin top bit and I have the middle sized extension tube between the wheel and the OAG. What guide camera do you have?

If you have the OAG in front of the flattener then add the length of the flattener minus the middle sized tube to the distance between the guide camera and the OAG. However, I think that would make that stalk too long to be stable, you'll probably get flex in there.

I'll get a photo tomorrow.
