M42 Camera Adapter (OAG)

The threads are buttery smooth and catch perfectly with my spacers. No wobble at all in the imaging train now, and it locks down tight without any play.

I paired this with the matching spacer ring and the whole train clicked together perfectly, no wobble at all. The M42 threading is smooth and tight, exactly what you need for precise camera alignment in astrophotography.

The threads are machined precisely—my camera sits perfectly flush with zero tilt or wobble. Screwed right onto my existing spacers without any frustrating cross-threading issues.
