About this app

Celestron® SkyPortal™
------------------------------------
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.
Control compatible Celestron WiFi telescopes with sophisticated mount modeling for quick and accurate go-to alignment.
Animate transits, conjunctions, eclipses, and other events with SkyPortal's Time controls.
Explore the sky with Night Vision turned on, and preserve your eyesight after dark.
Learn the history, mythology, and science of the heavens with SkyPortal's hundreds of object descriptions.
Browse hundreds of astronomical photographs and NASA spacecraft images
Access over 4 hours of audio commentary to guide you through the best celestial objects.

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.

SkyPortal’s telescope alignment incorporates advanced mount modeling, providing better pointing accuracy than other telescope systems which rely on a dedicated computer.

Piece of Garbage. I thought Celestron was the right choice when I bought my Telescope, all change when I started using this app, it drops a lot, does not track correctly, I waste too much time aligning objects and trying to track them for astrophotography, do not use this app. Its useless waste of time I have spend so many nights frustrated with the lack of fixing the app and all the bugs on it.

I really love the app! It does everything well! It is a joy to do a search and then look through the eyepiece and see what it is showing, but the three stars only for one major reason; THE PLACEMENT OF THE DAMN DISCONNECT TAB. I use the app on my phone where everything is somewhat cramped, and if after aligning the scope I want to goto, or do a search, I might accidentally tap the disconnect tab, and have to go through alignment over again. This has happened sometimes three times in a night!

I love the concept of this, and it does make alignment easier. But, it drops the connection whenever the screen locks, requiring you to close and restart the app to reconnect. Because the alignment data is stored in the app instead of the telescope, this data is lost and you need to realign. The app either needs to manipulate the telescope's alignment process, and be able to pick that back up, or write the alignment data to persistent memory and ask to resume.
