ECCO2 is the Environmental Computerized COntroller for EAGLE that automates the management of dew heaters during long exposure astrophotography. By adding the ECCO module to your EAGLE, it will automatically and continuously monitor the temperature, humidity and pressure around your telescope and the temperature of your lenses by calculating the dew point (the temperature below which dew condenses). This way it will automatically vary the heating of dew heaters connected to the dew heater ports of the EAGLE avoiding condensation on your optics.

The second generation ECCO now comes with USB-C type port, added pressure sensor, SMART control of temperature probes and DARK mode. ECCO2 is also provided with an ASCOM driver so can be controlled with any third party software and standard Windows 10 computers.

Valuable piece of kit and a must have for the Eagle 3 Pro

Having the knowledge of not only the temp and humidity, but also air pressure is proving to be quite valuable with my rig in suburban Sydney.
Just a quick and easy update of the Eagle Manager and I can confidently rely on the ECCO 2 to effectively control my dew heaters and allow me to enjoy lengthy and uninterrupted imaging sessions.
