Adapters for ESATTO 4" robotic microfocuser

The fit on my ZWO camera is perfectly snug, with no play at all in the threads. I was worried about back focus, but the adapter pair I got let me dial it in exactly.

The brass threads on these adapters mesh really smoothly with my ESATTO focuser. Fits well and does the job, though the price felt a bit steep for just a couple of rings.

The threads on the camera adapter side are clean and engaged smoothly with my main imaging train. The only small gripe is that the included set screws felt a bit short for my thicker telescope drawtube, but a quick swap fixed that. Overall, it does exactly what it needs for precise focus control.
