Seamless Thread Conversion for Astrophotography Setups
The ZWO M54-M48 Adapter is a precision-machined connection ring designed specifically for astronomy imaging gear, enabling you to bridge two of the most common thread standards in astrophotography — M48x0.75 and M54x0.75.
Whether you’re integrating cameras, filter drawers, electronic filter wheels or other accessories, this adapter makes it easy to convert an M48 male thread to an M54 male thread without adding significant optical extension.
This compact yet essential accessory helps you achieve a perfectly integrated system, reducing the need for bulky extension tubes or complex adaptors.
