حلقة CA لمسطح متعدد FC/FS FC-100DL، FS-102، FC-125

Finally, a way to use my flattener with my 100DL without weird adapter stacking. The CA ring threads on cleanly and holds everything perfectly square, no tilt issues at all. My stars are round edge to edge now, exactly what I needed.

I was worried about getting the spacing right, but the CA ring threads on smoothly and holds the flattener perfectly centered on my FC-100DL.

This ring mates perfectly with my FS-102, locking everything solidly in place. The threads are smooth and precise, and the edge of the glass is clean with no vignetting. My flats now process much more consistently.
