When you need a secure way to attach a CCD camera at the image plane of a CDK telescope, the Secure Fit Spacers get you the optimal back focus spacing. These spacers attach via four screws to the PlaneWave Hedrick and IRF90 Focusers. When coupled with a PlaneWave SecureFit CCD Adapter, they practically eliminate slippage, movement, and equipment drops. The spacers come in eight different lengths: 2.1″, 3.8″, 4.5″, 5.2″, 5.9″, 6.75″, 7.5″, and 8.25″.
These spacers are made for the CDK14, 17, 20, and 24 and do not work with the CDK12.5. The CDK12.5 Secure Fit Spacers have a different bore size.
