حلقة CA متعددة التسطيح FC/FS FC-60، FC-65

The machining on this adapter ring is so precise—it threaded on smoothly with zero play. Now my stars are pinpoint sharp across the whole frame. A simple but critical piece for anyone using a flattener with these scopes.

Finally got my flattener working perfectly with the FC-65—the CA ring threads on smoothly and snugly. This adapter makes the whole setup feel solid, and my stars are nice and round across the frame now.

Took a chance on this adapter to pair the flattener with my FC-65, and the fit is snug with no tilt that I can detect. The anodized finish matches the scope well enough, though I wish the ring came with a spare set of screws.
