SBIG CFW-10/ST TOA 減焦鏡用墊片 (TCD0021L)

I’ve been using this spacer for a few nights now, and the machined edges fit perfectly with my setup—no play at all. The threading is smooth, which made attachment straightforward even in the dark. For the price, it’s exactly what I needed for proper back focus.

Finally, no more guessing about spacing — this spacer threaded onto my TOA reducer without any wobble. The black anodizing looks great against the rest of the setup, and my CFW-10 sits perfectly square now.

Machined perfectly — the threads on this spacer mate with the TOA reducer without any wobble. Focus came out sharp on my first test exposure.
