Adapter 48mm auf M54

The adapter has an M54x0.75 external thread, such as is used in filter wheels or astro cameras, and a D = 48 internal thread.

Attention, the internal thread is not an M48x0.75 internal thread, it is cut a little too small and the pitch is also imprecise. A hobbyist or precision mechanic can make the thread suitable for M48x0.75 connection adapters.
