Internet connection
After installation and setup are complete the core functions of Night Sky do not require a wi-fi or cellular data connection.
The Stargazing Conditions, Night Sky Tonight and Night Sky News features require an Internet connection to function. Satellite data is occasionally updated in the background and this also requires an internet connection but Night Sky will continue to function even if this is not possible.

Installing Night Sky
1. Tap the App Store app on your Home screen.
2. Browse or search for Night Sky then tap the icon for the app.
3. Tap Get. You might need to sign in with your Apple ID. You will be offered the option to select the Premium version.
Night Sky is ready for use when it finishes downloading.

Tap on this icon on your device’s home screen to start Night Sky. Once the app has launched hold your device toward the sky and watch as the stars and celestial bodies appear on your screen!

Permissions
Geolocation permissions are needed to create an accurate Sky View and provide local push notifications.
Push notifications are needed to update you about the stargazing conditions, rising times of objects, International Space Station (ISS) flyovers, breaking news stores and other events. Notifications can be customised.
Access to the Calendar is required so that the app can suggest Night Sky Tours for upcoming vacations and trips in your Calendar and to remind you about planetary positions, meteor showers, space launches and other upcoming events.

Sky View
Sky View is the heart of Night Sky.
Sky View presents you with a real-time simulation of the sky as currently seen from your own location or other location of your choice. Over 60 million stars are included. It is a 360° view and you can move it around with your finger or by moving your device. You can zoom in on an object by “pulling apart” with two fingers.

Sky Appearance
The sky appears a deep blue in Sky View at all times, but in the Preferences menu there is an option to give the daytime sky a lighter blue hue.
In default view, the horizon is shown as a purple line. There are cardinal point indicators (N, NE, E etc) located on the horizon to show the direction you are facing.

You can add a simulated environment to the horizon (above) in the Preferences menu. These include simulations of the skyline visible from New York City, London, Paris and other major cities.
The stars are grouped into areas of the sky called constellations which are defined by some of the star patterns described by ancient civilisations or created by astronomers in historical times. Modern astronomers use 88 constellations. You can make these constellations more apparent in Sky View by selecting “Show constellation lines” in the preferences section. This will highlight the constellation’s shape by adding lines joining the brightest stars in the constellation.
For a historic perspective on the sky, you can add “Glass Mythology” figures to Sky View. These appear as transparent artistic impressions of the people, creatures and objects which inspired the constellations.
Both the constellation lines and glass mythology figures can be made to fade away if you prefer. You can do this in the Preferences menu.
You can select alternative views with the buttons in the upper right of Sky View.

Press this button to turn on Night Sky Blending to merge the Sky View graphics with the real sky as seen by the camera on your device. The graphics and text help you to identify objects in the sky.
Touching this symbol again returns to the simulated view.

Use this button to shift to Night Sky Compass mode. This is a quick guide to what you will see in the sky through the night. You can move the time back and forward with the slider control along the bottom. How many hours (plus or minus) you are offset from current time is displayed in a pink box at upper left. The stars and planets around the compass move as the time is adjusted, so that you can see which bright stars are visible at specified times and in specific directions.

Use this button to shift to Dark Adaptation View. This makes Night Sky appear with a dim red backlight. Using this mode when you are observing the sky helps to maintain your eyes’ dark adaptation.

An estimated percentage of the light pollution at the Sky View location appears in the lower right corner. Touching this will take you to the Light Pollution tab on the Menu Interface (Premium feature).

Light Pollution Simulator
Place two fingers anywhere in Sky View and move them up or down to increase or decrease star density. This will simulate different types of sky based on light pollution, from inner city skies to an excellent dark sky sites.

Sky Objects
Touching many objects, such as planets and bright stars, in Sky View will display a link which will take you to a screen of additional information on the object (based on data from wikipedia.org). Buttons at the bottom allow you to access addition features. There are:

Find Object

Add object to your Notifications

Go to 3D Model (Moons, planets and satellites only)

This the Planetary Landing button. Use it to switch Sky View location to a point on object’s surface (Moon and planets only)

3D Models

Many constellations, stars, planets and moons allow you to zoom into an Augmented Reality (AR) 3D model of the object.

This button allows you close the model.

This button allows you to view additional information on the modelled object.

This button allows you to share the model via iMessage with USDZ.

This button will add the rising time of the object over the horizon to your notifications.

This is the Planetary Landing button. Use it to switch your Sky View location to a point on the object’s surface (Moon and planets only)

Use these buttons to toggle between exterior and internal views of planets and moon. This reveals the details of the internal structure of the object.

This button will open a tutorial on how to explore objects in AR.

With a double tap you can pull planets, stars, constellations and satellites out of the sky to examine in AR. Object exploration creates a 3D object centre for you to explore in more detail. You can add a Siri shortcut and share planets via iMessage with USDZ. When you finish you can throw the object back into the Night Sky.
Tapping on a planet, dwarf planet or moon will also switch your Sky View location to a point on its surface.
