QuadTCC 間隔環

My imaging train is now perfectly dialed in thanks to this exact spacer length. The threads are smooth and consistent, making it easy to swap between scopes.

These spacers are machined so precisely that my QuadTCC achieved perfect backfocus on the first try, which rarely happens for me. The threaded rings engage smoothly without any binding, and the anodized finish matches my other gear.

I was worried about getting the exact backfocus distance right, but these spacers are precisely machined and the threads are butter smooth. Locked everything down perfectly with no tilt issues.
