Compatible with any astrophotography device: built in computer with Windows 10 Enterprise.

By including a powerful Windows 10 Enterprise computer (that is 100% compatible with any software and driver created for Windows 10 64 bit), the EAGLE will work with all devices (that come with Windows 10 64 bit drivers) and Windows 10 software. The Windows 10 Enterprise operating system is lighter-weight and more stable than traditional PCs with Windows 10 Home or other OEM versions that come preinstalled with useless bloatware. EAGLE 4 uses a 2.0 GHz Celeron processor (J4005 dual-core with Burst Mode up to 2.7 GHz and 4MB cache) and 4 GB of fast DDR4 RAM memory - both designed for low power consumption. This way you have the power you need to run any DSO astrophotography software with a device that’s easy on your battery, improving overall portability. The included high capacity SSD drive (faster and more durable over time than traditional spinning disks) allow you to save your data on the SSD drive in the EAGLE (or you can connect a 3.0 USB flash drive to one of the high speed USB 3.0 ports).

Compatible with any telescope: connect it to your telescope, any type.

Thanks to the special PLUS case, you can connect the EAGLE to any type of telescope: refractors, Schmidt-Cassegrains, Ritchey-Chretiens, Newtonians, and others. Thanks to the many threaded holes on the EAGLE’s chassis and the availability of various PLUS systems accessories (support rings, dovetail bars, dovetail clamps), connecting the EAGLE to your telescope is easy. By using EAGLE instead of a laptop or desktop computer, your telescope will have less cables and shorter runs that will move in unison with your telescope (this drastically reduces the potential for cable snagging or detaching while your telescope tracks the stars across the sky). The EAGLE also has lower power consumption, reducing the battery capacity needed to power your complete telescope all night long. The electronic internal components were designed for field use in extended temperature ranges. This way you can rely on it all night long including in higher humidity conditions as the small amount of internal heat generated by the processor slightly warms the chassis of the EAGLE, helping to prevent dew from forming on the body or EYE lens.

8 USB ports - four fast USB 3.0 ports and four USB 2.0 ports that can be remotely turned ON/OFF.

EAGLE allows you to connect and control many devices and should the need arise, you can also remotely turn on/off the USB 2.0 ports, instead of having to manually unplug or plug a cable! This can be a great feature to save power (you can also turn off the port you do not use) but you can also reset the port it in case of a device connection failure. Thanks to the EAGLE’s four USB 3.0 ports, you can connect and use the latest fast USB 3.0 cameras - With the faster processors of the EAGLE S and PRO models, they are a great choice for the high demands of planetary imaging, allowing high-speed video capture of the Moon, planets, and Sun at high resolution to the fast internal SSD drive.

Advanced power bridge with 7 power out ports - power devices directly through the EAGLE.

The EAGLE has a separate 12V power input that can run on up to 16 amps. From there, using a special internal board, power is distributed to seven power out ports - four 12V power out ports are designed to power your camera, mount, focuser, or other 12v devices. These ports are equipped with safety screw-type connections to prevent unwanted detachment of the cables and we have made special power cables (optional) for different devices. The three 0-12V variable power out ports are designed to power dew heaters without the need for an external controller. Control of these ports can be easily automated by adding the optional ECCO environmental module for EAGLE. A dedicated chip on EAGLE’s power board protects the electronics (both on the EAGLE and connected devices) from any overcurrents by temporarily disconnecting power in no more than 1ms in case of electrical problems - a lot faster than traditional fuses. Power is automatically re-activated once the problem has been resolved. Additionally, a special microcontroller allows you to adjust (+- 1A) the maximum current limit of the 12V ports. This way, if you want to connect a device to a 3A max port and that device has a maximum power consumption of 4A, you can increase the port limit to 4A.

GPS sensor with high gain antenna - to automatically detect latitude, longitude, elevation, date and time.

In order to control your telescope with maximum precision, it’s very important you provide your geographical position and local time in a very precise way. Thanks to the integrated GPS sensor the EAGLE now automatically detects your telescope elevation, latitude, longitude and local time by connecting to the satellites of the Global Positioning System. The external high gain antenna allows the EAGLE to detect GPS data in a very fast and precise way, even if you see only part of the sky (and even if you install the EAGLE in an observatory within a dome!). EAGLE automatically syncs the date, time and position data captured from GPS with Windows settings: this way the software you use for astrophotography will control your telescope with greater precision!

EAGLE EYE to monitor sky quality only where the telescope is pointed.

Did you ever want to check the sky quality of your telescope’s field of view? Have you ever dreamed of being able to monitor the sky all night long, even when your telescope is moving and while you’re asleep? The new EYE sensor automatically measures the sky brightness for you (in magnitude per square arc second - mag/sq arcsec) with a 5 degree field of view, only where your telescope is pointed! The EYE value is shown in real time in the EAGLE Manager interface where you can easily monitor sky quality measurements. EAGLE4 has two EYE sensors, one on each end of the EAGLE. Based on how you orient your EAGLE on your telescope, you can simply unthread and move the lens to the other sensor that is pointing to the sky, select the proper position of the lens in the EAGLE Manager interface, and you are ready to read the sky brightness in any installation.

Thanks to the special lens, the EAGLE EYE has a narrow field of view, so it measures darkness of the night sky only in the part of the sky where your telescope is pointed. This way the EAGLE EYE won’t be influenced, for example, by clouds that may be present in other parts of the sky. For the same reason, the proximity of your telescope or other accessories (like dew shield) won’t interfere with the measurements, also if you install the EAGLE close to your telescope and you have a long tube. The small amount of internal heat generated by the processor reduces the possibility of dew formation on the small lens.

DARK mode to turn off all the LED lights.

Every astronomer knows artificial lights reduce telescope performance, both in visual use and astrophotography. That’s why we designed the EAGLE4 with a new DARK mode feature that allows you to instantly turn off all the LED lights on the EAGLE, when needed! Not only this will prevent any influence on your telescope but it is also a great feature for your astronomy friends that may be close to you while enjoying the night sky together. Thanks to the new DARK mode, the EAGLE is now a welcome guest at star parties where standard computers may be prohibited because of uncontrolled light emissions from LEDs and screens (the EAGLE doesn’t need a screen to operate).

EAGLE Manager interface to easily control all the EAGLE’s features.

EAGLE comes with special "EAGLE Manager" software that starts automatically and provides an easy and intuitive interface, allowing you to:

Enable/Disable every 12V power out port: this way you can keep all your devices connected (for example, mount, camera, filter wheel, etc.) and activate them remotely when you turn on the entire system. Each port shows the current consumption that can also be monitored over time.
Check for GPS data: elevation, latitude, longitude, date, time and number of connected satellites
Check for EYE sky quality: select the sensor facing toward the sky and check for sky quality value
Set the power out voltage of the 3 x 0-12V power out ports: increase or decrease the power to dew heaters connected to EAGLE. Each port shows the current consumption that can also be monitored over time.
Activate DARK mode: this turns off all the LED lights.
Connect or disconnect devices connected to the four USB 2.0 ports: this feature is convenient in case of temporary crash of an autoguider or planetary camera, which can then be reset without the need to go to the telescope and disconnect/reconnect a cable.
Check power consumption and battery lifetime: if you power your EAGLE with a battery, a dedicated menu allows you to set the Ampere capacity of your battery and charge percentage when EAGLE is powered on, enabling you to monitor its expected lifetime.
Set WiFi connectivity: to access EAGLE in Access Point mode for field use (use your smartphone, tablet or external computer by connecting directly to EAGLE without the need for a WiFi router) or HOST mode for connecting to your existing network such as your home WiFi.
Set your automatic power routines: you can define port status “After power on” and “Before shut down” for the devices connected to the EAGLE. This way, for example, you can automatically turn on all your devices after you start the EAGLE and turn them all off when you shut down the EAGLE.

Powerful and fast WiFi 802.11ac with dual band (2.4 and 5 GHz) connection to remotely control your telescope from any device.

To operate EAGLE, you don't need a keyboard and mouse - You can control the EAGLE through a free dedicated app, available on any smartphone, tablet or personal computer running Windows, MacOS, iOS or Android. Turn the EAGLE on, then enable your device's WiFi connection and select the WiFi network provided by the EAGLE. Launch the remote control app and you will have the EAGLE desktop on your screen with access to all your astrophotography software. If you like, you can also configure the EAGLE to connect to a pre-existing WiFi or wired/ethernet network allowing remote access via the internet - perfect for remote observatories! Since the EAGLE doesn't use VNC or other software for remote control, it's faster and more stable. For your safety each EAGLE device creates a unique WiFi network, from any other EAGLE that might be nearby. To avoid any other issues at a star party, every EAGLE also has a unique access password known only by you. And if you prefer a wired connection, the EAGLE has also a gigabit Ethernet port so you can also control it through a wired network, which can be very useful in large observatories!

Optional ECCO environmental computerised controller for automatic dew heater control based on dew point.

By adding ECCO, (Environmental Computerised COntroller) to your EAGLE, you can automatically and continuously monitor the dew point (the temperature below which moisture condenses) by sensing the temperature and humidity of the air around your telescope and the temperature of your lenses. ECCO will then automatically vary the voltage to the appropriate EAGLE’s ports where your dew heaters bands are connected, keeping dew from forming on your optics. All of this with an automatic and easy to use device that you just have to connect to one of the EAGLE USB ports. 

PLUS aluminium case, to allow easy integration with any telescope and to support demanding payloads without flexure.

We designed the EAGLE case to be incredibly rigid. It is rigid enough to a support even a compact telescope in parallel (up to 8 kg). This way you can also install the EAGLE below your main telescope! Precise FEM simulations allowed us to design the EAGLE’s case in order to have a maximum deformation of 0.002 millimeters if loaded with 10 kg of weight. The EAGLE case comes with M5 and M6 threaded holes to seamlessly attach PLUS accessories (support rings, guide rings, dovetail bars or dovetail clamps), on at least 2 points to maintain the system's rigidity. For example, the EAGLE can be installed between the PLUS support rings and guiding rings, without any flexure improving the portability of your telescope and allowing it to be moved to the field pre-assembled, greatly reducing your setup time.

Performance comparison with a miniPC.

EAGLE4 not only offers exclusive features for advanced astrophotography, but also all the power of a real computer (superior to a Mini PC) to allow you to use any astrophotography software. In order to test its performance, we used the PCMark benchmark and compared EAGLE4/ EAGLE4 S / EAGLE4 PRO with one of the many inexpensive Mini PCs on the market (where we installed the same EAGLE4 operating system for a precise results comparison). As you can see in the picture below, EAGLE4 offers 32% more performance than a common Mini PC with Intel Celeron N3160 processor, 4GB of RAM and SSD disk; EAGLE4 S raises the gap further by bringing this difference to 109%; EAGLE4 PRO boosts everything to a wonderful +153%!
