Software
Night Sky 12 is designed for iOS/iPadOS 17 and watchOS 10.
It is compatible with:
iOS 14.0 or later
watchOS 7 or later
tvOS 14 or later
macOS 11 or above

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 Widgets, Stargazing Conditions, Night Sky Tonight and Night Sky News features all require an Internet connection to function. Satellite data is occasionally updated in the background and this also requires an internet connection. Night Sky can still be used without an internet connection but the app’s functionality will be reduced.

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 a free trial of the Plus version.
Night Sky is ready for use once it finishes downloading.

Tap on this icon on your device’s home screen to start Night Sky. After the animated opening you can review a short tutorial, then hold your device towards 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. Night Sky does not share your location data with iCandi Apps or anyone else.
Push notifications are needed to update you about the stargazing conditions, rising times of objects, International Space Station (ISS) and Starlink satellite flyovers, breaking news stories and other events. Notifications can be customised in the app’s Settings.
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.
Night Sky needs access to your device’s camera for its Night Sky Blending, Augmented Reality and Astrophotography features (explained elsewhere in this guide). The app only accesses your camera when you are using these features. Images and videos made while you are using Night Sky are not shared with anyone else.

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 1.7 billion stars are included. It is a 360° view and you can move it around with your finger or by moving your device (iPhone, iPad and Apple Watch only). On Apple Mac devices you can move around Sky View with your mouse or arrow keys.
You can zoom in on an object by “pulling apart” with two fingers on iPhones and iPads. To zoom in on Apple Mac devices, you can either double tap on the trackpad or double click the mouse.
As you zoom in more stars will become visible. An angular scale bar will appear at the top of the screen as you zoom in. This scale bar disappears when you stop zooming.
To zoom out “pinch in” with two fingers.
In Sky View, the Earth is “transparent” allowing you to look down to see the locations of objects under the horizon. If you zoom out when you are looking down, the view changes to a 3D model of the Earth (Night Sky+ feature only). You can turn this feature off in the Preferences section.

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. At higher zoom levels the sky background colour will change to black.
In default view, the horizon is shown as a purple line. There are cardinal point indicators (N, E, S, W etc) located on the horizon to show the direction you are facing. A compass rose is also placed high in the sky.

 

 

 

 

You can choose for the app to display a simulated environment on the horizon (above) in the Preferences menu. These include decorative simulations of generic urban landscapes and simulations of the skyline visible from New York City, London, Paris and other major cities. The app selects an appropriate environment based on your location. The displayed environment is representational only and may not match the view from a precise location.
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. Night Sky displays the 88 constellations accepted by the International Astronomical Union (IAU).

 

 

 

 

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 from the Preferences section. 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 or entirely removed if you prefer. You can do this in the Preferences menu.

 

 

 

 

Double tapping on a constellation’s name brings up a three dimensional view of the constellation which you can rotate with your finger to see the stars’ relative distances. Tapping on the X in the corner will return to Sky View.
As well as the planets and stars, Sky View includes important and beautiful deep sky objects. These include nebulae, star clusters and galaxies. These are identified with their common names or their catalog designations. Night Sky includes every object in the Messier Catalogue and objects from the New General Catalogue (NGC) and Index Catalogue (IC).

Sky Tags
You can personalise Night Sky by labelling objects or features in Sky View with a coloured Sky Tag for future reference. Night Sky will remember your Tags and they will be displayed in Sky View and be included in Sky Tours. Night Sky’s Search function can find your Sky Tags too. You can also share Sky Tags for other Night Sky users to find with iMessage and other services.
Creating Sky Tags
Hold your finger where you want the Tag to appear and a slider will appear to allow you to select your preferred colour. When a colour has been selected a tile will appear.

 

 

 

 

On this tile you can name the Tag and add notes (for example when you saw the star you are tagging, why it is important). You can link a photo to the Tag and edit the colour of the Tag. There is a range of Icons you can select for your Tag. Tags can be added to a category (Favorite, Memorials, Sightings, Observational Planning, Family or your own custom category). Select Done when you have finished creating your Tag. This will also offer you the option of adding the new Tag to your Notifications.
There is an alternative method to create Sky Tags by inputting the celestial coordinates of the object you wish to tag in the Sky Tags section of the Menu.
Using Sky Tags

 

 

 

 

Tapping on an existing Sky Tag opens a tile giving you multiple options.
View Tag: Tapping on this opens a tile with the name of the Tag, its astronomical name (when available) and its coordinates. Tapping on the blue Directions button will bring the Tag to the centre of the Sky View.
All Tags: Tapping on this opens a tile with a list of all your Sky Tags.
Share Tag: This opens a tile with options to share the Tag with other Night Sky users by email, messaging or social media apps. Shared Sky Tags appear as links in emails, messages and social media posts. When the recipient taps on this link Night Sky opens and the Tag is added to the list of Sky Tags.
Remove Tag: This allows you to permanently remove a Sky Tag.
Night Sky users with Night Sky+ subscriptions can create an unlimited number of Sky Tags. Users of the free version of Night Sky are limited to two Sky tags.

Light Pollution Simulator (iPhone and iPad only)
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.
You can select alternative views with the buttons in the upper right of Sky View.

Night Sky Blending (iPhone and iPad only)

Tap this button to access 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.
You are offered the option of adding the Sky View graphics to the scene from your device’s camera. This is ideal if you are using Night Sky outdoors. Alternatively, if you are using Night Sky indoors and a LIDAR scanner is installed on your device, tapping on this button offers the option to scan the ceiling. If you tap on the ceiling on screen Night Sky will intelligently “remove” the ceiling and replace it with a virtual window onto the Night Sky.
Tapping this symbol again returns to the simulated view.

Astrophotography Tools

Photo/Video Mode

Use image mode to take still images and video mode to take videos

Exposure and ISO settings
You can control how much light your camera lets in with these controls.
Turn ISO Lock on to manually override the auto light settings
The ISO sensitivity to light can be adjusted with the slider from 24 to 768.
Turn the exposure lock on to manually override the duration your camera absorbs light for.
Use the slide to manually set the time the camera absorbs light for from 0.001 second to 0.5 second.
Shorter exposures are possible with higher ISO settings but this will increase the “noise” in the image, reducing its quality. You can experiment to optimise these settings for the image you are making.

Digital Focus
Turn the Focus Lock on to manually control the digital focus of the camera with a slider.

Digital Zoom
Use this to manually control the digital zoom of the camera (x1 to x10) with a slider.

Star and Satellite Trails
This allows you to capture the trails of stars and satellites. It leaves your camera’s lens open for several minutes. For best results your device should be left stationary while you do this.

Night Mode
In this mode your camera becomes more sensitive but the images will be “noisier”. “Noise” is the term used to describe dots which may appear in your image.

Noise reduction
This function will help to remove these dots.

Object Optimisation
Select an option to use presets to automatically optimise your camera’s zoom and light input settings for capturing particular objects. You can select Moon, Stars and Constellations or Planet.

Image Alignment Tools
Use this function to select one of five possible grids (2×2, 3×3, 5×5, 9×9). A grid is superimposed over your screen to help you to align the object(s) in your image. The grid will not appear in your image.
