Stellarium Mobile is a planetarium app that shows exactly what you see when you look up at the stars.
This award-winning astronomy application will let you explore the sky and identify stars, constellations, planets, comets, satellites such as the ISS, and other deep sky objects in real time in the sky above you in just a few seconds, just by pointing the phone at the sky!
Stellarium Mobile has an easy to use and minimalist user interface that makes it one of the best astronomical applications for children and adults who want to discover the night sky.
• a catalog of over 600,000 stars displayed as a real time zoomable sky map
• a catalog of many nebulas, galaxies, star clusters and other deep sky objects
• asterisms and illustrations of the constellations for several sky cultures: discover how people see the stars in other parts of the planet
• artificial satellites, including the International Space Station
• realistic Milky Way and Deep Sky Objects images
• realistic landscape and atmosphere with sunrise, sunset and light pollution simulation
• accurate simulation of stars extinction, and atmosphere refraction
• 3D rendering of the major solar system planets and their satellites
• night mode (red) protecting your eyes when doing sky observation at night time
• view a night sky map of stars and planets for any date, time and location
Stellarium Mobile is created by two of the original developers of Stellarium, one of the best astronomy applications on Desktop PC.

This app has been incredible, and I’ve been using it for years. However, the latest version of stellarium doesn’t seem to be working well with the current iOS. The coordinate box for the currently selected object has a tendency of displaying garbled information. The same is true for the date and time inputs. The problem seems to be intermittent, and simply relaunching the app fixes the bug temporarily. Unfortunately, it will re-occur after a while.
One additional issue I have with this app is that it will not display the same coordinates as the desktop version for the sun & moon. The discrepancy is usually only a couple of arc minutes, but it is curious that there’s any difference at all. It may be due to the lack of elevation inputs, or the iPad version may be using fewer periodic & secular terms to model the sun & moon, but the two platforms ought to be in agreement for the same date, time, and location.
I set this up on my iPad and mounted it to my dobsonian telescope to use as a star chart and it has been pretty amazing so far. I don't have it set to motion so I just scroll on the screen to where I'm looking and star hop using stellarium to show me where I'm at by comparing it to my field of view. It's not flawless, but it's better than acceptable for finding deep sky objects, tracking the planets, and even satellites.
One thing I wish was offered was a telrad reticle overlay. That would make this app 100 times easier to use than it already is. The ability to see the size relation on screen and compare it through my telrad would enable me to speed up my star hopping faster than using a goto mount I'd bet.
I only gave four stars instead of five because in motion it seems to be off quite a bit although still useful, and because I feel that adding a telrad reticle overlay would then make it perfect. At least for me.
OK but a couple MAJOR problems.
I used the app a couple nights ago and everything seemed as it should be. But tonight I was trying to look back at that night on the app and it's not the same as what it showed then. In fact it was way off. I started setting the date back one day at a time until the moonset was at the right time and the date was 3 days off.
Second problem is finding a city. THERE IS NO WAY TO SEARCH FOR A CITY. If you are trying to find a city, first you have to scroll through a list of every country in the world. So the US takes a while to get to. THEN it shows a scroll list of every city it has in that country. So scroll, scroll, scroll (looking for Sedona - the city list doesn't list a state). First time I got half way there and touched just off the list and it went away. But it didn't start where I left off. Oh no. I had to start over again only to find Sedona is not on the list. Can someone tell me in what universe does this make sense???
With Family Sharing set up, up to six family members can use this app.
