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
Simulate the night sky and plan your observing session with a custom list of tonight’s best objects based on your exact time and location. Look ahead to see when Jupiter’s Great Red Spot will be visible, animate transits, eclipses, and other celestial events. View hundreds of photos or listen to more than four hours of audio narration to enhance your stargazing experience.

•Simulate the night sky from anywhere on planet Earth, up to 100 years in the past or future.
•Compass Mode (with compatible devices): Hold your device up to the sky for a real-time synchronized display of celestial objects – from star names, constellations, planets, to nebulae and galaxies.

Computerized Telescope Control
Pair your device to your compatible Celestron WiFi telescope, align with Celestron’s patented SkyAlign™ technology, and you’re ready to explore! Identify objects instantly. Tap any object and your telescope automatically centers it in the eyepiece.

This is a terrible downsized version of a great app (sky safari). It will not consistently go-to, it won't keep the settings that you've put in the hand controller (max elevation,cordwrap!etc.) the cordwrap setting doesn’t work—if you try to use this with your scope remote it will wrap itself to a grinding standstill. The only reason I have this is that it is the only thing offered with Celestron's Wi-fi module. I'm junking both the module and the program and going back to the Orion setup that allows use of SkySafari

Newest view—-IF you have sky safari already you can use the Celstron wi-fi module by bypassing this junk and selecting “Celestron Wi-Fi “in the telescope drop down in the Telescope settings in SkySafari .It ties you in and works!! (Even though your scope is NOT a Wi-Fi scope)

Great app


I don’t know why this app has such a low rating I love it
its simple and easy to use. it doesn’t have all the features that sky safari offers but it’s easy of use more than makes up for that. I have a nexstar 5se and sky portal module and while I have never really gotten the sky align features I love the manual alignment with up to 10 stars

Wow, this is bad!

Something seems terribly wrong with this app. No deep space objects visible at all, despite the menu setting saying otherwise. The deep space objects are there, but you have to enter their names individually in the search menu. Seems to be missing half of the basic features in the free version of Sky Safari. I got this hoping to use it to control by CGX mount. But it’s unlikely this app will be any use for that.
