PrimaLuceLab ESATTO Focuser

The ultra-slim 32mm profile is designed to solve backfocus issues common in astrophotography. By taking up less space, it allows you to add other accessories like filter wheels or off-axis guiders without exceeding the limited backfocus distance of many telescopes.

Yes, the ESATTO is built to support a payload of up to 5kg. This is more than sufficient for most dedicated cooled astronomy cameras paired with heavy filter wheels and complex imaging trains.

This level of precision allows for extremely fine adjustments, ensuring your stars remain pinpoint sharp throughout long exposure sessions. It effectively eliminates the 'soft' focus issues that can occur with coarser focusing mechanisms.

The ESATTO is highly adaptable and compatible with a wide range of telescopes, including the Celestron EdgeHD 8". You will need to ensure you have the correct adapter for your specific telescope model to securely attach the unit.

Yes, the unit features built-in WiFi, allowing for remote control of your focus without needing a physical USB cable tethered to your computer. It also includes a USB-C port if you prefer a hardwired connection.

The dedicated ARCO port allows you to seamlessly connect and control PrimaLuceLab's ARCO camera rotators and field de-rotators directly through the focuser. This simplifies your cable management and integrates rotation control into your primary astrophotography software.
