EAGLE4, our best control unit for remote control and power of telescopes and astrophotography, is available in 3 versions. In fact, also if the EAGLE4 basic version has enough computing power to run any deep-sky astrophotography software and device, when we designed the EAGLE4 we wanted to provide also faster processors option and added storage space, in order to offer the best match for everyone's needs based on different applications that every astronomer have with his telescope. Then, all the EAGLE4 units shares the same advanced features, but they differ for computing power, power consumption, ports configuration and prices. Let's see differences and find out which version is the best for you.
