M68M to M48M Adapter – 1.5mm Back Focus
This precision-machined M68M to M48M adapter is designed for astrophotography imaging trains where exact back focus spacing is required. With an ultra-thin mechanical thickness of just 1.5mm, it allows fine spacing adjustment without exceeding reducer or flattener back focus limits.
Ideal for adapting M48-threaded cameras, filter wheels, and accessories to M68-based imaging systems, this adapter is commonly used in advanced astrophotography setups involving reducers, flatteners, off-axis guiders, and spacers.
CNC-machined to tight tolerances and finished in matte black to minimise internal reflections, it provides a clean, secure, and professional-grade connection within complex imaging trains.
