Adapter TS-Optics with male M63x1 thread and male M54x0.75 thread

The Adapter TS M63x1 to M54x0.75 is the perfect solution for those who are looking for a solid, stable and vignetting-free connection between their focuser and the optical chain. Thanks to its two precision male threads, it allows mounting cameras, filter wheels, filter boxes or off-axis guiders with M54x0.75 female thread on focusers equipped with M63x1 female thread.

Unlike adapters based on M48 thread, this model eliminates the usual "bottleneck", ensuring optimum illumination even with full-frame sensors, which is essential in modern astrophotography.

In addition, the adapter can be separated into two pieces, offering an intermediate M63x1 male thread, very useful for adapting spacers or additional accessories. This makes it an extremely versatile component for advanced setups.

Teleskop-Service Tip

If the 6 mm M54 thread is too long for certain accessories (such as filter wheels with short female threads), you can adjust the length using M54 tuning rings. They are simply placed over the external thread, avoiding blockages or mechanical interference.
