M68M to M54M Adapter – 1.5mm Back Focus | Dark Clear Skies Observatory Controller All published readout noise measurementsM68M to M54M Adapter 1. 5mm Back Focus This precision machined M68M to M54M adapter is designed for astrophotography imaging trains where exact back focus spacing is critical. With an ultra thin mechanical thickness of just 1. 5mm, it allows fine spacing adjustment without exceeding reducer or flattener back focus requirements. Ideal for converting between M68 and M54 threaded components, this adapter is commonly used in advanced imaging setups
