Robin - it's easy.

I used a Sky90 50.8mm adapter (TKP35110) which screws onto the FS60-C focuser draw tube directly, or via the CAA which I use.

I then removed about a centimetre off the end of a standard Bintel 2" Quartz Dielectric diagonal so that it had enough in-focus with the CAA fitted. Works a treat, and clear 2" aperture right the way through. The two collar screws on the adapter secure the short diagonal tube very snugly, and the CAA lets you observe with the EP at the optimal angle.
