Celestron Skyportal (SkyQ Link 2) and Primaluce Lab EAGLE CORE for Celestron Mounts

With Celestron’s SkyPortal device (formerly known as SkyQ Link 2), connected to the Italian Primaluce Lab’s EAGLE CORE, you can control many Celestron mounts using the SkyPortal or SkySafary planetarium app, you can start autoguiding and capturing with a DSLR camera using EAGLE OS software, in order to easily perform astrophotography via WiFi from any iOS or Android smartphone or tablet! Usually SkyPortal device creates its own WiFi network that you connect to but in this article we’ll see how to connect it to EAGLE CORE: this way you can connect your iOS or Android device to EAGLE CORE WiFi and take full wireless control of the telescope that will be easier to use and transport, a perfect instrument for astrophotography.

In this example, we’ll see how to setup a SkyPortal device connected to a Celestron computerized mount with a NexStar handset.
