This adapter allows you to connect any camera or accessory with an M48 × 0.75 female thread to the draw-tube of the PrimaLuceLab ESATTO 2″ robotic focuser (which uses an M56 male thread at the draw-tube end). It also incorporates a stop‐ring feature so you can fix the rotational orientation of your camera or accessory for precise framing or cable/cable‐management alignment.
Key identifiers:
- Reference/SKU: PL3600216
- Optical thickness (when installed): ~4 mm (1.5 mm for the adapter body + 2.5 mm for the stop ring)
- Price: ~US $114 (varies by dealer)
Features & Benefits
- Thread conversion: Lets you go from the ESATTO 2″ focuser’s M56 draw‐tube thread to a more common M48 × 0.75 female interface — so you can mount any M48‐threaded camera or accessory.
- Stop-ring for rotational alignment: The adapter includes a stop‐ring so you can lock the rotational angle of your camera or accessory relative to the focuser. That’s especially useful when you care about sensor orientation, cable exit direction, or aligning guiding ports, filter wheels, OAGs, etc.
- Minimal added optical path: With only ~4 mm of optical thickness added, it helps keep your back‐focus requirements tight — important for fast optics or complex imaging trains.
- Build & compatibility: Designed specifically to match the ESATTO 2″ focuser, so it fits its draw‐tube thread and mechanical stack cleanly. This reduces potential misalignment or flex compared to aftermarket generic adapters.
