Hey Chris, Mine reaches focus at 228.5mm from the back of the scope. The ONAG fills in quite a bit of distance unfortunately. I have put some pics up with some measurements.
The QHY9 filter wheel is the main problem in the system. But I have eliminated all the bits marked with a green spot, the ONAG will now thread straight into the Moonlite draw tube, shaving off 24mm. The ONAG will connect to the filter wheel with a new adaptor, eliminating 7mm. And the final adaptor will allow the camera to connect to the filter wheel with a piece only 1mm thick, removing a further 14mm. There is still about 2mm to remove, but I have 6.5 mm of in travel in the moonlite. It will be a close fit but I'm sure it will work
