PrimaLuceLab ESATTO Robotic Focuser

Yes, it is designed specifically for heavy imaging trains. With a 10 kg payload capacity, it provides the stability needed to prevent flexure or slippage, even when using large sensors, filter wheels, and off-axis guiders.

No, you don't need a physical hand controller. The unit features integrated WiFi and a USB-C port, allowing you to control focus directly from your computer or via the virtual handpad interface on your smartphone or tablet.

The ESATTO offers an extremely fine resolution of 0.04 microns per step. This level of precision is ideal for achieving critical focus on high-resolution sensors, ensuring your stars remain sharp across the entire field of view.

Yes, the focuser includes a dedicated port specifically for an optional electronic rotator. This allows you to integrate camera rotation into your automated workflow without needing extra cables or complex connections.

The large 102mm free aperture is designed to minimize vignetting, even with large-format sensors. However, you should ensure your telescope's draw tube or baffle system can support this clear aperture to fully realize the benefits.
