I had seen 55mm mentioned for this reducer on an ED80 and greater spacing than that for the ED72 that I have, but at 55mm it seems to be almost spot on. I have to get rid of a compression fitting that is introducing some tilt before I can really fine tune it.
That 55mm assumes I am measuring from the same place as Skywatcher, I was measuring from the base of the sensor side threads but they might measure from the top of the threads, they don't specify.
