Photograph Stars, Meteors, Satellites and even Nebulae with your iPhone and NightCap Camera
The golden rule: Keep your iPhone still.
Iphone – For best results, use a tripod. Even a cheap smartphone tripod will be fine. If you haven’t got one, you’ll need some way to hold your iPhone in place while you take photos.
Using Special Modes
NightCap Camera includes 4 special camera modes designed to make photographing the night sky easy:
To open the special modes tap the Star button: Then tap the > button to switch between Camera Tools and Special Modes.
1 Stars ( )
To photograph the stars, simply turn on Stars Mode from the special modes menu. Stars Mode sets the camera up for you with the best settings for stars, so all you need to do is put your device in a tripod or a firm position pointing at the part of the sky you wish to photograph and tap the shutter.
After pressing the shutter the app will start a 3 second timer (to avoid blurring if you move the device slightly when tapping the button), then it’ll take a 10 second exposure. Wait until you hear the shutter sound or see the shutter button go from red (capturing) to white (ready).
Here’s an example of what’s possible:
2: Star Trails ( )
Capturing star trails is easy, all you need to do is turn on Star Trails Mode, tap the shutter button once to start capturing, then wait at least 15 minutes before tapping the shutter again to save the photo.
The longer you wait, the longer the trails will be – you can see them forming on screen. This is a 90 minute photo, pointing north (the star in the centre is Polaris, the Pole Star):
3 Meteors ( )
Meteors (or shooting stars) are also easy to photograph, especially during a meteor shower. There’s plenty of information on viewing meteors and an excellent timetable of meteor showers at Meteorwatch.
To photograph meteors, just turn on Meteor Mode, point your device at a clear patch of sky, and tap the shutter button. The app will take a photo every 5 seconds until you tap the shutter again to finish.
While it’s capturing, the app will automatically scan every photo for potential meteors. It rejects any that are ’empty’ and saves the rest to the camera roll. You can then review the photos to see what it caught.
Please note that Meteor Mode will save quite a lot of photos (typically between 30 and 150 per hour, depending on sky conditions). A clear, dark, starry sky will give best results, while trees and planes will result in more photos being saved.
Here are some meteors captured with Meteor Mode:
4 ISS / Satellite Flares ( )
Many satellites orbit the Earth and can be seen easily at night – they look like a moving star, and don’t flash like a plane. The biggest, brightest and best known is the ISS (International Space Station).
There are some good sites and apps that will show ISS (and other satellite) viewing times for your location:
Satellites look great if you capture their trail as they pass across the sky. To do so, turn on ISS Mode, point your device in the direction the ISS or satellite is expected to pass, and be tap the shutter to start the photo (be sure to start before the pass is due to begin!) Once the ISS or satellite has passed, tap the shutter again to finish.
5 Nebulae ( )
It’s possible to photograph nebulae, galaxies and other deep space objects with an iPhone and NightCap Pro, but these objects are small and very, very faint so to capture them you’ll need a reasonably big telescope (ideally with a motorised mount that tracks the movement of the stars automatically) and an adaptor to attach your iPhone to it.
