After a bit of encouragement from Mike S. I had a go at assembling the image train.

The total distance from the back plate of the RH200 to the focal plane of the camera is 109.1mm. The Atlas focuser is fully retracted. The focal plane of the RH200 is 115mm from the back plate. So focus is within the range of the Atlas focuser which is 9mm.

Once the Altlas focuser is extended the three screws that hold the zero tilt adapter can be loosened and the orientation of the camera and filter wheel can then be reset.

Looks like we are in business.
