I finally got the right connection for my camera's 2" nosepiece, and the M81 threads fit perfectly on my ESATTO. The machining is clean enough that there's no play or tilt when I rack the focuser in and out. It solved a frustrating adapter hunt.

The threading is precise and smooth, it locked onto my ESATTO without any wobble. I used it last night to attach a 2" diagonal and the view was perfectly stable.
