M54(M)Canon 10mm adapter (020071)

The threads on this adapter are noticeably smoother than another one I tried, so attaching it to my camera feels precise. It’s a solid, well-machined piece that gives me confidence for long exposures. Exactly what I needed for my setup.

Fits my Canon body perfectly and locks on without any wobble, which is exactly what I needed for my imaging train. The 10mm spacing is spot on for my setup, so I didn't have to mess with extra spacers.

The threading is precise and smooth, locking onto my camera body with zero wobble. Finally, my telescope setup feels solid without any frustrating play.
