FC/FS 멀티 플래트너 CA 링 FS-128, FS-152

Perfect fit for my FS-128—the threads engaged smoothly and the ring’s inner diameter matched the telescope’s rear cell precisely. It’s noticeably lighter than I expected, which helps balance the whole imaging train.

Machining is flawless—the ring threads onto my flattener without any play at all. Hooked it up to the FS-152 and the field correction is noticeably cleaner across the whole frame.

I was worried the CA ring wouldn't mate smoothly, but it threads on perfectly and the multi-flattener now locks in solid. No more star elongation at the edges of my FS-152 frames.
