PrimaLuceLab ESATTO 2" Robotic Microfocuser - PLLEST2

The PrimaLuceLab ESATTO 2″ Robotic Microfocuser (PLLEST2) is a high-precision, compact focuser built for demanding astrophotography and visual applications. It combines advanced mechanical engineering with smart electronics to deliver reliable, ultra-fine focus control.

Key Features

• Crayford-Style Mechanism with 18 Ball Bearings
  Provides exceptionally smooth motion and a high load capacity — supports up to 5 kg (11 lb) without noticeable flexure. 

• Low-Profile Design
  The focuser has a slim body only 67 mm thick, keeping your imaging train compact and minimizing back-focus requirements. 

• High Resolution & Travel
  Offers 15 mm of travel with a remarkable 0.04 micron per step resolution — ideal for precise autofocus routines like V-curve focusing. 

• Generous Free Aperture
  Provides a 50.9 mm clear aperture, allowing unvignetted light paths for large cameras and accessories. 

• Remote Control Capability

  • USB-C Port: Reliable connection to a Windows computer or EAGLE control unit. 

  • Wi-Fi: Built-in Wi-Fi lets you operate the focuser from your smartphone or tablet using the ESATTO Virtual HandPad app, even while physically connected to a computer. 

  • ASCOM Drivers: Fully supports third-party astrophotography software for autofocus and preset position control. 

• Camera and Accessory Mounting
  The drawtube terminates in an M56 × 0.75 male thread, accommodating a variety of optional camera adapters. With included stop rings, you can securely lock in your camera at a precise rotation angle. 

• ARCO Port
  Includes a dedicated port for PrimaLuceLab’s ARCO 2″ robotic rotator, enabling seamless remote control of camera rotation (or field de-rotation) with just a single short cable. 

• Sturdy, Yet Light
  Despite its robust design, the ESATTO 2″ weighs about 835 g, making it practical for a wide range of telescope setups.
