Sophia F. ★★★★★

I was worried about sensor distance calculations, but this spacer slipped right onto the reducer threads with zero play, making collimation much easier than I expected.

Sebastian F. ★★★★★

The fit between the TCD0021 and my SBIG ST camera is absolutely precise, threads engage smoothly without any cross-threading. I’ve been using it with the TOA reducer and the whole setup stays perfectly collimated even after swapping filters.

Miles J. ★★★★★

Finally a spacer that lets me connect my SBIG camera and filter wheel to the TOA reducer without any guesswork. The machining is precise enough that I didn't have to shim anything to get perfect back focus.
