Aurora K. ★★★★★

Screwed into my imaging train with zero wobble — the threads are precise enough that I didn't even need to use thread lock. It's a simple piece, but having the right adapter makes a huge difference for back focus calculations.

Ava ★★★★★

The M54 to M48 adapter fit perfectly into my imaging train and the threads are buttery smooth, no binding at all. My camera now sits exactly at the right backfocus distance, which was a huge relief.

Scarlett W. ★★★★★

This adapter tightened up my imaging train perfectly, the threads are smooth and engage without any wobble. It solved the connection issue between my reducer and filter wheel in one simple piece.
