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.

App is simplistic perfection

I was introduced to sky portal when I got a celestron go to telescope a short time ago and it’s become my primary astronomy app since it easy to use, contains a through library of visible objects in the night sky of the northern hemisphere and with the compass mode gives you a rough view of the sky you are looking at in real time, my only recommendations for anyone using this app would be to use it on a iPad or tablet over a smartphone as the arrow keys used to slew a telescope and the crosshairs used to target an object can be tricky to use on the smaller screen. It would be nice if there were more satellites and objects listed maybe that’s what Sky Safari Pro is for and I may upgrade one day but at the moment Sky Portal meets the means for my backyard astronomical observations. App is 4 stars

Great App

I use this app with my Celestron 11” Edge HD and the CGX mount. I also utilize the Star Sense camera with it for alignment and it works beautifully. The only issues I have are the Celestron focus control is very sensitive and very confusing and almost impossible to use and updates to the app to include data for new comets are very slow to occur for example the latest new comet Neowise has been visible for a while now and it is not listed in SKy Portal but has been in the Sky Safari app for quite some time now.

Great app for learning and controlling telescope. One improvement.

I love this app however I have one suggestion for improvement: When using the audio guides in the Info section, let the audio playback continue to work when the screen locks or auto locks. Many people have their phones set to auto lock after as little as 30 seconds and when this happens any audio playback currently in progress instantly shuts off when the phone locks. Only unlocking the phone will instantly resume playback. Seems like that improvement should be possible based on many other apps out there being able to play audio while the phone is locked. Thank you!
