FC/FS マルチフラットナー CAリング 76

Took a chance on this adapter ring for my FC-76 and it fits perfectly—the threads are clean and the flattener locks on without any wobble. Starfield sharpness is noticeably improved at the edges now, exactly what I hoped for.

The threads on this ring are machined perfectly smooth, so my flattener screwed on without any wobble or fuss. I'm getting sharp stars across the whole frame now with my FC-76, exactly what I needed for my wide-field shots.

Installing this ring was surprisingly simple — it threaded onto my FC-76 without any fuss and locked the flattener at the exact spacing needed. First test shots show stars looking round all the way across the frame, which is exactly what I was hoping for.
