PrimaLuceLab ESATTO 2 Focuser

Yes, it is designed for substantial imaging trains. It features a 5kg payload capacity, which is robust enough to handle most cooled CCD or CMOS cameras paired with filter wheels and off-axis guiders without experiencing flexure.

Absolutely. The ESATTO 2 includes built-in WiFi, allowing you to manage focus remotely from your computer, tablet, or smartphone, in addition to the standard USB-C wired connection.

The system offers extremely high precision with a resolution of 0.04 microns per step. This level of detail allows for the minute adjustments necessary to achieve critical focus for sharp, high-resolution astrophotography.

The ESATTO 2 is highly versatile and compatible with a wide range of telescope designs, including Schmidt-Cassegrain, Refractor, Newtonian, and Cassegrain systems. You will need to ensure you have the correct adapter for your specific telescope model.

The dedicated ARCO port allows you to directly connect and control a PrimaLuceLab ARCO camera rotator. This creates an integrated, all-in-one system for managing both focus and camera orientation through a single interface.

With a thickness of only 67mm, the ESATTO 2 is designed to be compact, which helps minimize back-focus consumption. This makes it easier to fit into imaging trains that have tight spacing requirements, though you should always verify your specific optical train's back-focus needs.
