We've tested it and found that it is compatible with the Skywatcher Skymax-127 127mm Maksutov that has a tube diameter of appr. 144.7mm, however we've heard it from a customer that his tube ring was slightly different and it was not compatible with his Skymax-127.
So, please make sure you actually measure the outer diameter of your telescope to make sure it is compatible before you commit to buy. If the tube rings are slightly larger than the tube, you might fill up the gap with two sided thick sticky tape (i.e. 3M).
Please note that you'll have to remove the dovetail bar to be able to attach the tube rings. We looked inside the tube and we cannot see nuts, but please check out your telescope just in case...If there are no nuts, then you'll have to worry about the two tiny holes the removed screws will leave behind...
