M68M to M48F Adapter – 1.4mm Back Focus

This precision-machined M68M to M48F adapter is designed for astrophotography imaging trains where precise back focus spacing is essential. With an ultra-thin mechanical thickness of just 1.4mm, it enables accurate spacing without exceeding reducer or flattener back focus requirements.

Ideal for connecting M48 male accessories to M68-based imaging systems, this adapter is commonly used with cameras, filter wheels, off-axis guiders, field flatteners, and focal reducers.

CNC-machined to tight tolerances and finished in matte black to minimise internal reflections, it provides a clean, secure, and professional-grade connection within advanced imaging setups.
