محول Ceravolo CDK إلى OPTEC-4300 (19840)

This adapter fit perfectly on my Ceravolo CDK astrograph, and the 6-inch outside diameter matched the existing hardware exactly. The installation was straightforward and the threads engaged smoothly without any cross-threading. I'm glad to have the limited back-focus option working now.

The adapter threaded onto my TCF-S3 without any wobble, which was my main worry with a third-party part. The 6-inch diameter mated perfectly to the back of my CDK, saving me from having to machine a custom spacer.

The 6-inch outside diameter fit perfectly onto my Ceravolo CDK's back plate—no shims needed. Threaded on smoothly and locked down solid, exactly what I needed for precise focuser alignment.
