CCD轉接環，SBIG STL至PlaneWave SecureFit

The threads on this adapter matched perfectly with my SecureFit spacer, making assembly straightforward. It feels solid and well-machined, giving me confidence it won't introduce tilt in my imaging train.

Machined surfaces are perfectly flat, so the camera sits square to the optical axis without any fuss. The threads engage smoothly, and the whole assembly feels rock solid once tightened down.

The anodized finish matches the rest of my setup perfectly and the bolts lined up without any fuss. I was worried about achieving the right back focus, but this adapter got me spot on with the SecureFit spacer.
