M54M to M48M Adapter
This M54 male to M48 male adapter joins a component with a M54 × 0.75 female thread to one with an M48 × 0.75 female thread. Both ends of the adapter have external threads.

Commonly used to adapt cameras, filter wheels, off-axis guiders, spacers, reducers, and other M48-threaded components within M54-based imaging systems, this adapter allows clean reconfiguration without unnecessary bulk.
CNC-machined to tight tolerances and finished in matte black to minimise internal reflections, it provides a secure, professional-grade connection for demanding astrophotography setups.
