Does such an adapter exist?

I want to set up a widefield rig with an EFW2, a Nikon 180mm F2.8 lens and a QHY9 CCD.

The back focus of the camera is 16.3mm, and the EFW2 is 22mm thick.  AFAIK the back focus of the Nikon D800 is 46.5mm, so I am aiming to replicate this distance to use my lens with the QHY9.

46.5mm - (16.3mm + 22mm) = spacing available = 8.2mm

 

Is it physically possible to get an 8mm adapter for this purpose?

 

TIA

CS

Adam.
