SecureFit Spacers For CDK 14, 17, 20, & 24

PlaneWave Secure Fit Spacers – Precision Backfocus for CDK14–24 Systems

Engineered for secure, precision imaging setups, PlaneWave Secure Fit Spacers provide optimal backfocus spacing when attaching CCD cameras to CDK14, CDK17, CDK20, and CDK24 telescopes. These robust spacers bolt directly to the PlaneWave Hedrick and IRF90 Focusers via four screws, ensuring a tight, slip-free connection for heavy imaging payloads.

When paired with a PlaneWave Secure Fit CCD Adapter, these spacers virtually eliminate movement, sag, or accidental detachment—making them ideal for observatories and remote imaging systems.
