Starmap: Amateur stargazing with a GPS tour guide
But I am no expert, and to help me understand what I can see in the sky, both by eye and by telescope, I rely on my phone and its apps. One of my favourite astronomy apps is Starmap, $5 on iOS. The main feature of this app is its virtual sky display. This is a re-creation of the sky above you, calculated from your GPS coordinates. It shows you where the stars, moon, planets and other heavenly bodies are. This display rotates and pans as you move your phone, so you can hold it up in front of you and figure out what stars or galaxies you’re looking at. You can zoom in for more detail if you find something interesting, and tap on a planet or a star to see details about it. The display can be switched to a night mode, which turns the graphics red so as not to spoil your night vision.
It’s elegantly designed, and the display is easy to read. Starmap excels in its extra features, which are useful even if you’re an astronomy novice. Clicking on the “tonight”
