“The deeper you’re able to look, the greater the insight into these many and varied objects you’ll get”Space is many things: cold, dark, inhospitable, unimaginably vast and almost a perfect vacuum. But it’s not empty. Stare up at the sky after the Sun has gone down and the dark canvas that surrounds us is perforated by countless pinpricks of light. These tiny specks are the planets, stars, nebulae, comets, constellations and galaxies that occupy the nothingness and light the night sky up with fascination.The sight of these objects hanging in the sky is impressive enough when seen with just your eyes. But bring a pair of binoculars or a telescope into the equation and you open a window onto another world filled with marvels and curiosities. And the deeper you’re…

stargazing with a smartphone

Your smartphone can be a powerful accessory during an observing session. By combining GPS positioning and an accelerometer, your phone can tell not only where you are on the planet, but exactly where you’re pointing it; cue planetarium apps that show you exactly what you’re looking at in the night sky.There are apps to help you plan observing sessions, find satellites and the International Space Station. There are apps that aid astrophotography, and provide the latest astronomical updates. Over the page, we look at 15 of these essential tools for astronomy.ABOUT THE WRITEREclipse-chaser and dark skies expert Jamie Carter is the author of A Stargazing Program for Beginners: A Pocket Field Guide. ■…

Stellarium Mobile Sky MapPrice: £2.99/£2.19/£1.49Platform: iOS/Android/Windows PhonePros: Realistic views; red-light mode; light-pollution sliderCons: Mostly technical data on starsThis planetarium app from the creators of the original and free Stellarium computer software impresses by keeping it real. As well as a virtual horizon, it has an option to mimic what you can see with the naked eye, and even a light-pollution adjuster. Overlays of the constellation lines, and equatorial and azimuthal grids can be superimposed. There’s also an easy-to-reach red-light mode and an unexpected section on the star lore of other cultures, including Inuit, Navajo and Aztec.https://noctua-software.comGoSkyWatch PlanetariumPrice: £3.99Platform: iOSPros: Target-search; celestial grid design; red-light modeCons: Bright stars only; obvious and invisible planets are treated the sameThis app for casual stargazers treats bright stars and planets like targets against a celestial…

SkySafari 5 ProPrice: £38.99Platform: iOS/AndroidPros: Remote control of Go-To telescopes; extensive data; custom observing lists; red-light modeCons: Expensive; a huge app at 1.7GB; requires telescope accessories No app goes as deep as SkySafari 5 Pro. On its own it’s a great astronomy app: you can create observing lists, check celestial coordinates, get ISS/Iridium satellite notifications, view images from the Digitized Sky Survey and even explore an intergalactic map of where an observing target is in the Universe relative to the Sun. However, this app is both expensive and huge in terms of file size. Using it to remotely control a computerised Go-To telescope requires a separate adaptor to let the app communicate with the setup, which can cost several hundred pounds.http://skysafariastronomy.comUniverse2goPrice: FreePlatform: iOS/AndroidPros: Free app; excellent audio narration; accurate augmented…

astrophotography

Adobe Photoshop ExpressPrice: FreePlatform: iOS/Android/ Windows PhonePros: Effective noise reductionCons: Fewer options than desktop version If you’re doing astrophotography or creating nightscapes using a camera with Wi-Fi, this app version of Photoshop makes a good stand-in for the desktop software so popular with astro imagers, letting you edit and check photos on the go. Key features include sharpen, clarity and exposure sliders, but most useful is a clever noise-reduction feature that automatically zooms-in on the image. It also includes shortcuts to upload finished images to everything from Adobe’s Creative Cloud to social media.www.adobe.comPhotoPillsPrice: £9.99Platform: iOS/AndroidPros: Precise positioning for Sun; Moon and Milky WayCons: Complex interface takes some getting used toWant to capture that iconic moonrise or moonset photo where our lunar companion glows orange as it hangs above the horizon?…

Cosmic WatchPrice: £4.99/£3.35Platform: iOS/AndroidPros: Creative design; encourages a new perspective on stargazingCons: Large app at 178MBTime is not a number, it’s a precise position in space, as you’ll quickly learn from this stunning 3D app that’s both a standard world clock and an astronomical timepiece. You look onto Earth from above your actual GPS location, and see which stars and constellations are overhead. Meanwhile, the changing positions of the Sun, the Moon, the planets on their orbits and even the shifting position of the Milky Way beyond are all integrated to create an app packed with detail.http://cosmic-watch.comNASAPrice: FreePlatform: iOS/Android/Kindle FirePros: Live rocket launches on NASA TV; latest images from NASA missionsCons: NASA’s Astronomy Picture of the Day images are scattered through the appWho can resist watching a rocket launch live?…
