Primaluce Lab ESATTO 3" Robotic MicroFocuser
ESATTO (EXACT) 3" robotic micro focuser!
ESATTO robotic microfocuser is also available in a larger 3" version: 76mm free aperture, 25mm of draw tube travel, 8kg of payload capacity and an incredible resolution of 0,04 micron per step! The perfect solution for apochromatic refractors and Ritchey-Chretien or Cassegrain telescopes, and heavy imaging trains with large cameras and accessories like off axis guiders, filter wheels and adaptive optics. And you can also expand ESATTO features by adding the ARCO robotic camera rotator!
The ESATTO 3" is the robotic microfocuser that is the perfect choice for many telescopes like large refractors, Ritchey-Chretiens or Cassegrains! ESATTO is specifically designed for astrophotography but, thanks to specific technologies developed by PrimaLuceLab, it also has the Virtual HandPad with WiFi control from smartphone or tablet. Forget about external controllers and cumbersome hand pads - ESATTO is the ALL-IN-ONE focuser that has all the features you’ve dreamed of in a compact, sturdy focuser design.

Large diameter for more free aperture and weight load capacity
Compared to the 2" model, ESATTO 3" offers a greater free aperture (76mm against 51mm of ESATTO 2") so it is perfect for astrophotography with telescopes such as large apochromatic refractors, Ritchey-Chretien or Cassegrain and heavy cameras with accessories like off-axis guiders, filter wheels and adaptive optics. The large free aperture also allows the use of special focal reducers or correctors. A special design with 28 bearings allows to increase the load capacity to 8 kg.
The best performance in a micrometric focuser
ESATTO 3" has all the advanced features included in the ESATTO focusers: connection to Windows control computer (or EAGLE) with a robust USB-C port (you can connect ESATTO to any USB port thanks to the cable included in the package), control and setting software with ASCOM driver to use also with any astrophotography software, remote control via WiFi using the dedicated ESATTO Virtual HandPad app (to control it even without a computer
Many adapters available to connect to many telescopes and cameras
We know that a perfect focuser is nothing without a solid connection to the camera. That's why, instead of using a normal 2" visual back, ESATTO 3" offers a M81x0.75 male thread and, through a complete series of optional camera adapters with stop ring, it allows you to directly connect the most common DSLR, mirrorless and CCD or CMOS cooled cameras directly at the focuser. The stop ring allows you to lock the camera at a precise angle to better frame the object to be photographed. The stop ring adapters are available in many different sizes: this way you can connect, with maximum rigidity and comfort, any camera or accessory. We have also prepared several adapters to connect ESATTO 3" to many telescopes!
Connect with a single cable to ARCO to remotely control also your robotic camera rotator
ESATTO includes a special port allowing ARCO, the robotic camera rotator, to be directly connected. With ARCO, you can remotely control the rotation angle of your camera in order to achieve perfect framing of the object you want to record. ESATTO and ARCO are designed to work together - You will need only one short interconnect between the two
