ZWO Adapter M54 to M48: Two Standards Connected
This adapter converts an M48 x 0.75 male thread to M54 x 0.75, the size of modern full-frame cameras and accessories. It is 5 mm thick but adds no optical length, so the backfocus of your setup is preserved exactly.
Two grooves on one side make loosening and tightening easy, even with gloves on or in tight setups. This allows you to connect filter wheels, OAGs, tilt adapters, and correctors with different mounts without improvised adapters.
Features
- Connect M48 to M54 thread
- No optical length: backfocus remains exact
- Grooves for easy assembly, even with gloves
- Anodized aluminum, light and strong
Compatibility
For coupling accessories with M48 and M54 mounts, such as filter wheels, off-axis guiders, tilt flanges, and correctors.
