Celestron’s newest planetarium app is an astronomy suite that redefines how you experience the night sky. Explore the Solar System, 120,000 stars, over 200 star clusters, nebulae, galaxies, and dozens of asteroids, comets, and satellites—including the ISS. SkyPortal includes everything you need to experience the night sky in an exciting new way. When connected to a compatible Celestron WiFi telescope, you can automatically point the telescope to any object in the database and view it with great detail.

Planetarium Features

No Deep Sky Objects

Just downloaded this app to reinstall for the 4th time because no deep sky objects show up. Come on guys, this is a deal breaker and very sloppy product maintenance. Fix this problem now. It is imperitive in order to be able to properly control my EDGE HD8. There is no excuse for this error!!!! No more stars until this fixed!

Love this app

Love this app, makes star gazing a lot more interesting, would like to know if there will be an update in the future that will include tracking starlink satellites ? Not sure if it’s relevant because they apparently will be positioning them so they are invisible to the naked eye but figured it would still be interesting to know where they are in the night sky even if they do ‘darken’ them or not
