Wanting to change your stock focuser because it isn’t sturdy enough and lacks precision? Do you want to improve the internal focuser of your SCT telescope? ESATTO is the next generation robotic focuser for telescopes, specifically designed for astrophotography but, thanks to specific technologies developed by PrimaLuceLab, also works extremely well for visual use. 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.
- Crayford style focuser with 18 ball bearings, specially designed for very high load capacity (up to 5 kgs) with no flexure
- Low profile design with only 67mm thickness.
- 15mm focuser travel with an incredible resolution of 0.04 microns per step!
- Special adapters to easily connect to many different telescopes.

- USB-C connector offering greater reliability and can be connected to any USB type port thanks to the included cable.
- Remote control with WiFi from any smartphone, tablet or computer and ESATTO Virtual HandPad app also for visual use!
- Many camera threaded adapters with stop ring on the camera side to rotate and keep the camera in the optical axis.
- ARCO port to easily connect the ARCO camera rotator to the ESATTO without the need for additional data or power cables.
- Weight: 835 gr.
The new ESATTO robotic microfocuser was born from our extensive experience in astrophotography and engineered with the uncompromising quality of PrimaLuceLab. We wanted to create the best motorized focuser in the world, with all the latest technical features, resulting in a compact and beautiful design only 67mm of thick.
The special Crayford design with 18 ball bearings allows ESATTO 2” to have an impressive 5 kgs (11 lb) payload capacity with the focusing smoothness that is required by modern astrophotography techniques (eg. autofocusing with V-curve). ESATTO 2” has a draw tube with 51mm of free aperture, and 15mm of travel, offering to an incredible read resolution of 0.04 microns per step!
You don’t need to worry on how to connect ESATTO to your telescope - You can choose among the many models and adapters available! You can easily connect ESATTO 2” to telescopes like Schmidt-Cassegrains, Aplanatic Schmidt-Cassegrains, refractors, Cassegrains, Newtonians, and more! ESATTO truly is the universal focuser and if you can’t find an adapter for your telescope, just contact us!
ESATTO has been specifically designed for easy remote operation in order to let your telescope take advantage of all the latest technology in astrophotography. ESATTO comes with a sturdy USB-C port (which you can connect to any USB type port thanks to the cable included in the box) to connect to EAGLE or any Windows computer (tested with Windows 10 computers), and control it via the provided FOCUSER Manager software or ASCOM driver. When connected to one of the USB 3.0 ports on the EAGLE (or any USB ports of Windows computers capable of at least 1A), the ESATTO can be powered and controlled via the one cable!
ESATTO has built-in WiFi remote control capability so you can control it from any smartphone, tablet or computer! Just connect your device to the WiFi network of ESATTO and start the app - You will be able to control the focuser by using the dedicated ESATTO Virtual HandPad app. Thanks to convenient preset settings, you can easily record and move the focuser to specific predetermined positions - Great for visual use! WiFi control works even if ESATTO is also connected to a computer so you can control it simultaneously from 2 devices.
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 2" offers a M56x1 male thread (to let you attach SkyWatcher/Orion reducers for ED 80, 100 and 120 refractors) 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.
ESATTO includes a special port allowing ARCO, the robotic 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!

Esatto 2 moves quickly, quantifies the focuser position, has programmable presets that you can use for instance to narrow down to optimal focus, and eliminates focuser shift and the vibration from touching your focuser - and thus the telescope.
Together these qualities makes it very fast to assess overall seeing conditions, find sub-seeing focus - where the clear image will appear once those brief moments of still seeing occur - and to refocus for your camera, particularly with the help of your device’s own focuser helpers, like FWHM and the brightest pixel. Very helpful on filter change and to check focus over the course of the night.
Finalmente ho potuto installarlo sul mio nuovo RC8. Con l'adattatore PL3600235 è stato un gioco da ragazzi. Devo dire che mi ha soddisfatto pienamente sia per la robustezza che per la stabilità (ho ruota portafiltri a 7 posizioni e una camera CCD QHY9). La sua interfaccia software è semplice ed intuitiva e non ho avuto il minimo problema nella configurazione e poi nell'uso...non posso dire altro di essere pienamente soddisfatto.
