Hi,
You can use the tilt adapter which you can see it on the first attachment.
If you buy the cfw earlier than 2019 August and the model looks like the model on the second attachment, you should first open the cap of the cfw and unscrew the filter wheel, then unscrew the 6 screws to take off the adapter in the end. And than you should screw the tilt adater to replace the adapter in the end. Of course you should then install the filter wheel and cap.
After the process, you can use the tilt adaper to connect QHY600 directly with the 3 handscrews on the tilt adapter. The final is like the third attachment.
Best Regards!
