Assuming this is an early FSQ.
There is 120mm of Backfocus from the back of the CAA to the image plane.
Where you run into problems is putting in OAGs and electronic focussers in between.
I think you should be OK but not sure what adapters you have between the CAA and the nosepiece adapter.
Be careful - that rear element is very close to the adapters so make sure the nose piece doesnt somehow protude inwards too close !
