Multi CA Ring 65D

The Takahashi Multi CA Ring 65D is a precision spacing ring specifically designed for the FCT-65D telescope when using the 1.04x multi-flattener optical system. This adapter ring mounts between the rear of the multi-flattener and the imaging camera, providing proper optical spacing to maintain the telescope's performance during wide-field astrophotography. Essential for FCT-65D users seeking to leverage the multi-flattener's field-flattening capabilities for deep-sky imaging with DSLR and cooled cameras.
