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

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.

No search feature anymore?

I cannot seem to find the search feature any more.

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)

A software failure due to limited scope. Has drop out connection to my Celestron 1100 CPC.

I ordered the module and assumed it was a problem with it. Sent it back for repair. In the meantime I purchased the Sky Safari module package and also the Sky Safari Pro app from apple App Store. Man did it ever work great!! Just received the repaired Sky Portal module. Still did not work. After reading other similar problems with the Sky Portal app., I must conclude that the app is overpriced at ‘free’.

It appears that Celestron’s Sky Portal app is lacking the required software to fit the job required. Do not waste your valuable time on this app folks!!!
