I've used digital calipers to get the distance down the tube to the center of the focuser and transfered that measurement to the other side of the tube. However, that measurement would change when the focuser is moved.
Moonlight focusers have collimination screws, no shims.

You sticky tape a couple of A4 sheets together so you can make a ring around your tube (tight fit). Then you mark the center of the hole where you're going to fit your focuser in. Then remove the paper, fold it over the dot you did and on the other fold you make another dot. Then place the paper ring over your tube again and center the first dot into your focuser hole again. The second dot marks the intersection of the tube and the focuser axis. Drill a small hole in the tube so you can see it.
