ESATTO 2" robotic focuser

ESATTO 2" robotic focuser

NOTE: it is recommended to purchase as additional accessories the ADAPTOR TO CAMERA and also the ADAPTOR TO TELESCOPE

ESATTO is the new generation robotic focuser featuring advanced motor and electronics that you control with EAGLE or any Windows computer by connecting it to a USB port, or via WiFi using the Virtual HandPad on your smartphone or tablet! The 2" version of the ESATTO 2" has 50.9mm of free opening, 15mm of drag tube travel, 5kg of load capacity and an incredible resolution of 0.04 microns per step. And you can also expand ESATTO's functionality by adding the ARCO robotic camera rotator!

do you want to replace your standard focuser because it is not robust enough and lacks precision? Do you want to upgrade the internal focuser of your SCT telescope? ESATTO is the latest generation robotic focuser for telescopes, designed specifically for astrophotography but which, thanks to the specific technologies developed by PrimaLuceLab, also works very well for visual use. Forget about external controllers and uncomfortable hand pads: ESATTO is the ALL-IN-ONE focuser that has all the features you have dreamed of in a compact and robust focuser design.

The best focuser mechanics and electronics in a compact body
The ESATTO robotic focuser was born from our extensive experience in astrophotography and was designed 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 of only 67mm thickness and 50.9mm free aperture.

Designed to give your telescopes the best performance for astrophotography
Crayford's special 18 ball bearing design allows ESATTO 2" to have an impressive payload capacity of 5 kgs (11 lb) with the smooth focusing required by modern astrophotography techniques (e.g. V-curve autofocusing). the ESATTO 2" has a drive tube with 50.9mm of free aperture, and 15mm of travel, offering an incredible reading resolution of 0.04 microns per step!

Many adapters available to connect to many telescopes
You don't have to worry about how to connect ESATTO to your telescope - you can choose from the many models and adapters available! You can easily connect the ESATTO 2" to telescopes such as Schmidt-Cassegrains, Schmidt-Cassegrains Aplanatics, refractors, Cassegrains, Newtonians, and more. ESATTO is truly the universal focuser and if you can't find an adapter for your telescope, just contact us!

Designed for remote control via a USB-C port from the EAGLE or from any Windows computer with a standard USB port.
ESATTO has been specifically designed for easy remote operation in order for your telescope to benefit from all the latest technology in astrophotography. ESATTO comes with a robust USB-C port (which you can connect to any USB-type port thanks to the cable included in the box) to connect it to EAGLE or any Windows computer (tested with Windows 10 computers), and control it with PLAY astrophotography software or the ASCOM driver. When connected to a USB port with at least 1A capacity, the ESATTO can be powered and controlled through a single cable!

Designed for remote control via WiFi, from any smartphone, tablet or computer via the ESATTO Virtual HandPad app
ESATTO has WiFi remote control capability so you can control it from any smartphone, tablet or computer. Just connect your device to the ESATTO WiFi network and start the app - You will be able to control the focuser using the dedicated ESATTO Virtual HandPad app. Thanks to convenient presets, you can record and move the focuser to specific preset positions - Great for visual use! WiFi control works even if the ESATTO is also connected to a computer, so you can control it simultaneously from 2 devices.

Focuser drive tube with M56x1 thread and stop ring for a perfect connection to the camera
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 an M56x1 male thread (to allow you to attach SkyWatcher/Orion reducers for ED 80, 100 and 120 refractors) and, through a complete series of optional camera adapters with stop ring, allows you to directly connect the most common DSLR, mirrorless, CCD or CMOS cooled cameras directly to the focuser. The stop ring allows you to lock the camera at a precise angle to better frame the subject to be photographed. The stop ring adapters are available in many different sizes: in this way you can connect, with maximum rigidity and convenience, any camera or accessory.

Connect with a single cable to ARCO to remotely control also the camera rotator and field de-rotator
ESATTO includes a special port that allows you to directly connect ARCO, the camera rotator and the field de-rotator. With ARCO, you can remotely control the rotation angle of your camera to achieve perfect framing of the subject you want to record. If you have an alt-az mount, you can use ARCO to de-rotate the field without the need for an equatorial wedge. ESATTO and ARCO are designed to work together - you will only need a short interconnection between the two!
