ESATTO 2" robotic focuser (PrimaLuceLab, SKU: PLLEST2-B ) is a precise, remote-controlled focuser designed for refractors and compact astrophotography telescopes. The Crayford mechanism supported by bearings ensures play-free operation, and the resolution of 0.04 µm per step allows for perfect focusing even with full-frame cameras.

Key Features of ESATTO 2"

• 51 mm free aperture – no vignetting for full-frame matrices
• working travel 25 mm with a resolution of 0.04 µm/step
• axial load capacity 5 kg – stable operation with filter wheel and corrector
• USB-C interface for controlling PLAY, ASCOM or INDI software
• built-in Wi-Fi (Virtual HandPad) – remote control via browser
• dedicated ARCO port – power supply and control of the ARCO 2″/3″ rotator with one cable
• status LEDs with the option to dim – no interference with visual adaptation
