ADAPTER M54 x 1 MALE TO M48 MALE 5mm

This adapter consists of a male M54 x 1 thread on one end and a male M48 x 0.75 thread on the other. Optical thickness of the adapter is 5mm.

This is very useful for connecting accessories such as filter drawers or filter wheels with a female M54 x 1 thread to accessories with female M48 x 0.75 threads.

Note: This is not the standard M54 x 0.75 thread as found on most accessories! Instead, this features M54 x 1 threads which are found on some Sky-Watcher Newtonian focusers.
