Primaluce Lab EAGLE & The ZWO ASIAIR - A Comparison

Advancements over the past couple of decades in wireless technology have changed the way astrophotographers control their cameras and telescope mounts. As systems become more streamlined, a wireless hub has become a crucial component in a great imaging setup. These lightweight, compact hubs allow for hands-free control via the wireless device of your choice, better power management, improved alignment, among other features, making your astrophotography system smart.

The PrimaluceLab EAGLE and ZWO ASIAIR are both popular choices and come in a variety of models to fit your system's needs. In April 2023, both ZWO and PrimaluceLab introduced new versions of their hubs.  Need help making a choice?  We're here to help!  Open Monday through Saturday.  Give us a call 818.347.2270 or email us at [email protected]
