Simple remote control

The ESATTO has been specifically designed for easy remote operation via a USB-C port of the EAGLE or from any Windows computer with a standard USB port. This allows your telescope to 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, and control it via the provided ESATTO software or ASCOM driver. When connected to one of the USB 3.0 ports on the EAGLE (or any USB port of Windows computers capabley of at least 1 A), the ESATTO can be operated and controlled via only 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 the convenient preset settings, you can easily record and move the focuser to specific predeterminated 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.

Focuser draw tube with M56x1 thread and stop ring for a perfect camera connection

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 and M56x0.75 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 to 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.
