The best stargazing apps can take your observation of the night sky to the next level, whether that's using augmented reality (AR mode) to identify stars or looking up the next lunar eclipse.

However, the bright light emitted by smartphone screens can prevent your eyes from adjusting to the dark. If you're using one of the best telescopes, you'll want to preserve your night vision even more. Fortunately, there are ways to all but eliminate this problem.

Why are bright screens bad for stargazing?

When you step out into the dark, it can take up to 20-30 minutes for your vision to adjust. The rod cells in your eyes build up a chemical known as rhodopsin, which gives you night vision.

However, bright light bleaches that chemical, negatively impacting your night vision. So when you look through a telescope, binoculars or just turn your eyes to the night sky after peering at a bright phone screen, it'll be harder for you to pick out fainter objects such as galaxies and nebulas.

One way of fixing this problem is simply to put your phone away and wait another 20-30 minutes. But if you're using a stargazing app to help you navigate the night skies, that's not really an option.

The good news is that, between individual stargazing apps and your phone's own built-in features, you can minimize the impact of your smartphone's screen light.

How to block white light in stargazing apps

Many of the best stargazing apps will let you enable a red light filter or similar, though this option may not always be present in the free version. Here's how to do that in three of our favorite stargazing apps:

SkyView: Tap the screen, tap the horizontal lines, tap on Settings, then Display, then Night Mode and Red.

Star Walk 2: Tap the horizontal lines, tap on Settings, then tap the button next to Night Mode.

Sky Tonight: Tap the horizontal lines, tap on Settings, then Tools, then Night Mode.

All these modes will minimize the amount of white light coming from the app. However, be aware that this is only within the app. Once you go back to your phone's main menu, it will be at full color. With the red screen naturally looking darker, you may have turned up the brightness on your phone, so making the switch away from the app will be quite the shock.

If you want to dim your whole phone or put it into red light mode, here's how to do that on Android or iPhone.

How to block white light on Android phones

On Android, there are several ways to minimize the impact of bright light, depending on the model and make of phone you have.

One near-universal option is to dim your smartphone. Swipe down the notification panel from the top of the screen and you'll see a brightness slider. Slide this to the left to dim your phone.

We'd also recommend disabling adaptive brightness in the Display section of your phone's settings. You may also have an Extra Dim option in the Accessibility menu — just don't dim the screen to the point of not being able to see it at all!

Some Android phones, such as recent Samsung and Google Pixel models, also offer a Red Filter. On some, you'll find this in Accessibility, then Vision Enhancements, then Color Filter. You can then choose the color you want and also tweak the opacity.

All the above options will let you continue to use your smartphone for stargazing, while minimizing its negative impact on your night vision.

How to block white light on Apple iPhones

As with Android phones, iPhones have a built-in option to dim the screen brightness. In this case, you swipe down from the top of the screen and look for the vertical brightness slider, represented by a sun icon. Reduce the slider as much as you're comfortable with, dimming the screen while still keeping it visible.

Beyond that, recent iPhones also offer the ability to apply a color filter, again via their Accessibility options. Here's how to do that.

First, tap on the Settings icon, then pick Accessibility. Select Display & Text Size and go to Color Filters. Tap the Color Filter button. Then, pick Color Tint and move the Hue and Intensity sliders all the way to the right.

Want to educate young children about the wonders of the cosmos? Depending on the time of year, your location and the weather, your hopes to see the night sky in real life might not be as easy as heading into the backyard and peering up. That's why one of the best star projectors might be the solution.

That's why we've picked out six star projectors that actually deliver scientifically accurate images, from projections of the northern hemisphere to breathtaking pictures from the Hubble Space Telescope.

Any one of these will turn your home into a private planetarium. Each comes with several swappable images, and you can purchase additional slides/discs for the Homestar and Pococo models. If you're seeking to stimulate a child's interest in space and STEM or just take your friends on a journey through space, these are the scientifically accurate projectors to purchase.

Whether you are a seasoned astronomer or a newcomer to the hobby, the best stargazing apps have the potential to seriously enhance your skywatching experience. But it's easy to overlook just how useful these portable programs can be.

That's why we've put together this guide to getting the best use out of stargazing apps, from identifying stars and constellations through to seeking out dark sky sites and beyond. You will wonder how you ever managed without them.

So read on and get ready to take your stargazing to the next level. And if you're wondering how else technology can take the work out of skywatching, we've also rounded up the best smart telescopes.

Using stargazing apps

Before we explore specific uses, there are a few things you need to know about using the best stargazing apps on your Apple or Android device.

Firstly, while some apps support offline use, you'll typically need a mobile or Wi-Fi signal with data to make the most of these apps.

Also, some apps lock certain features behind a paywall. Pay for Stellarium Plus, for example, and you get an additional 2 million deep sky objects, the ability to connect to certain telescopes and more.

Finally, while many stargazing apps are relatively intuitive, we'd recommend you familiarize yourself with them at home before taking them out into the field.

Identifying stars in the field

One of the most common and convenient uses for stargazing apps is identifying stars, constellations and more, just by pointing your phone's camera at them.

It really is that simple. Take Sky Tonight, which we think is the best stargazing app for AR (augmented reality). Launch the app, grant it camera access and turn it towards the object you want to identify. The name will appear on screen and you can also tap to learn more about it, whether it's a star, constellation, planet or nebula.

Conversely, you can also use the app to find specific objects in the sky. Want to view Uranus at opposition this Nov. 25 but aren't sure where to look? Search for it in Sky Tonight and the app will point you to it.

Identifiying stars from photographs

Being able to identify night sky objects in the field is a real boon, but what if you've already taken a photograph and want to identify which stars were visible?

That's where apps like Sky Walk 2 come in. If possible, you should return to the location where the photograph was taken, but if that's not possible, you can input GPS co-ordinates and Sky Walk 2 will show you the view from that location.

Next, using the clock icon and slider, alter the date to the exact time you took the photograph (or as near as possible). You will then be shown the night sky as it was at the time. You can now tap on the star or stars you want to identify and Sky Walk 2 will tell you the name.

Sky Walk 2 isn't the only app to offer such a facility, but in Sky Walk 2's case this feature is present in the free version of the app.

Finding dark sky sites

It's a sad fact that light pollution has made it harder for astronomers to study the night sky. While the planets in our solar system are still visible, sky glow obscures more distant objects, such as fainter stars.

You could travel to a dark sky reserve but, with the aid of one of several stargazing apps, it is also possible to find dark sky sites closer to home.

Apps like Sky Safari and the simply named Light Pollution Map will show you the light pollution levels locally and globally, estimated on the Bortle scale. The latter app colors the map, with pink the most light pollution and black the least.

In just a few seconds you can find out how light polluted your local area is, and use the map to find a location nearby where the sky is dark, or at least darker.

Planning a stargazing trip

Are you planning a stargazing trip? Then you'll be happy to hear there's an app for that. There are several, in fact, but Sky Safari has all you need to plan your next outing. You can create observation lists, find out when and where objects are visible, and while it won't book your tickets for you, it comes close.

Our reviewer Jamie Carter used the app to plan his observations of conjunctions, specific moon views and astrophotography opportunities. Coupled with its light pollution map, it will be a huge help in putting together an itinerary for your skywatching trip.

Troubleshooting stargazing apps

Hopefully you'll have a smooth experience, but if you're having issues, here are a few things to try.

• Take your phone out of its case. Magnetic clasps can interfere with internal sensors.
• Make sure location services are enabled. Many apps use GPS to show you the correct view.
• Check your phone's clock. If your clock is not set accurately, apps may display an incorrect sky
• Swoop your phone in a figure eight motion. This can help calibrate your phone's "compass".
• Make sure you have a signal, and that data is enabled. Unless the app has an offline mode you will still need a connection. Signal may be poor at dark sky sites.
• Check each app's permissions. Location aside, Augmented Reality (AR) stargazing apps will need camera access.

Alongside the usual interstellar shenanigans, Marvel's Guardians of the Galaxy Vol. 3 revealed the origin story of Rocket Raccoon. This Lego model, which comes with an utterly adorable model of Baby Rocket, captures one of the most dramatic moments of the film, Rocket's escape from his captor. And if you're fast, you can grab this Lego Marvel Baby Rocket's Ship at a bargain price.

Made up of 330 pieces and for builders aged 8 years and up, this should only take you a couple of hours to build, maybe longer for little fingers. It's a seriously striking ship, and is sure to entertain Guardians of the Galaxy fans of all ages. Aside from Baby Rocket, it also comes with a minifigure of grown-up Rocket Raccoon, both of which can be perched in the opening cockpit.

Pilot's seat aside, there are several other play-friendly features. You can also lower the landing gear and given how light it is, you or younger builders can swoosh this striking ship around the house. Why not make up your own Guardians of the Galaxy Vol. 4? Maybe you can catch up with Doctor Doom and prevent Avengers: Doomsday from happening.

Looking for a quality camera that marries style and performance? Look no further than the Nikon Zf. Despite its vintage looks, it's one of the best Nikon cameras you can buy and with its excellent low-light performance, we also rank it as one of the best astrophotography cameras. Now, thanks to this deal, it's the cheapest it's been since last year's Black Friday.

Save $453 and get the Nikon Zf camera, on sale for $1,747 at Amazon.

In our Nikon Zf review, our expert called it "A great buy that offers excellent value for money when compared with some of the much more expensive Nikon models." Now less than $1,800, this is a steal for astrophotographers and photographers in general.

• We've got you covered with reviews and rankings of the best telescopes, binoculars, star projectors, cameras, drones, Lego, streaming and more.

What's not to love about this Nikon Zf camera? We ranked it as the best camera under $2,000, before inflation pushed it past that price point, and this deal makes it the cheapest it's been since last Black Friday.

Not only does this full-frame mirrorless camera offer excellent low-light performance, so much so that we think it's one of the best cameras for astrophotography, it's a brilliant all-rounder too.

In their Nikon Zf review, expert Jase Parnell-Brookes awarded it four-and-a-half stars, discovering that its strengths go far beyond its vintage stylings, remarking that "It delivered an impressive dynamic range and performed well in various lighting scenarios."

And, while you can point and shoot, the Nikon Zf is packed with controls designed to enhance your experience. From changing the ISO and ISO sensitivity, through to switch to black-and-white mode, you have complete control over your images. That much choice may seem daunting but the buttons and dials are intuitive enough that using them becomes second nature.

There are Nikon cameras out there that can beat its 24.5 MP images, but you'd have to spend significantly more. The Nikon Z8, for example, is over half as much again. If you want to make your money count, the Nikon Zf is the camera to buy. However, you'll have to hurry if you want to make the most of this deal. As we write this, there are just a handful of units left in stock.

Key features: 24.5 MP FX CMOS Sensor, Z mount, 100-64000 (expandable to 204,800) ISO, 4K UHD 30p video, 1 lb 9.1 oz / 710 g weight, 1SD UHS-II + MicroSD UHS-I card slots.

I've got three telescopes in my home, but the Celestron FirstScope is my first stop when it comes to stargazing. Now this super-portable, beginner-friendly tabletop scope is $60 at Amazon, even cheaper than Prime Day!

Save 20% on this moon-themed Celestron Firstscope at Amazon

What makes the Celestron FirstScope so fantastic? It's all down to ease of use and portability. There's next to no assembly and once you've unboxed it, you can pick it up in one hand and head outside.

• We've got you covered with reviews and rankings of the best telescopes, binoculars, star projectors, cameras, drones, Lego, streaming and more.

Even though I've got two bigger telescopes in my home, a Skyatcher Classic 200P and a Bresser Solarix 114/500, I wouldn't dream of parting with my Celestron FirstScope. This tabletop scope is so easy to use and so portable, you can just grab it, head outside and get stargazing.

No fuss, no mess, no scraping the door frame because folding the tripod down seems like too much work. It's also small enough that you can sling it in a backpack, ideal for hopping on your bike and pedalling away from light pollution.

It comes with 20mm and 4mm eyepieces, but you can also trade up to any of the best eyepieces. As a tabletop telescope you'll need to find something to rest it on but a wall or even a trash can will do. And if you're a beginner, or buying for children, you'll be delighted with how the FirstScope performs. We think it's the best tabletop telescope for kids.

And, despite its size, it offers respectable views of the night sky. Testing the scope for our Celestron FirstScope review, expert Gemma Lavender was able to view Jupiter, Venus, Saturn and the moon as well as the Pleiades. It may not be one of the best telescopes for deep space, but if you're new to stargazing, you'll find plenty to wow you.

The lack of a finderscope is slightly disappointing but you can purchase one separately and, even without one, this is an impressively capable telescope, at a price that won't break the bank. It really is that simple. Want to watch Saturn at opposition this Oct. 4? Grab your FirstScope, perch it on a table or wall, and home in on this ringed planet. It's excellent for moonwatching too, especially if you're short on time. We think this is the best tabletop telescope for kids and beginners will love it too.

Key features: Newtonian reflector with Dobsonian mount, 2.99-in (76mm) aperture, 11.81in (300mm) focal length, 20mm and 4mm eyepieces.

What's not to love about Star Wars' AT-ST? First glimpsed in The Empire Strikes Back and heavily featured in Return of the Jedi are typical of the Empire; designed to instil fear, but laughably impractical. I can just imagine the Emperor laughing.. "Yes.. yes.... more like a chicken!" as his engineering team roll their eyes. And now, thanks to Lego, you can own this super-detailed Lego Star Wars Ultimate Collector Series AT-ST.

Made up of 1,513 pieces, it's for builders aged 18+ or over. It comes with an information plaque and a minifigure of an AT-ST driver. It is designed to be fun to build as well as looking striking as a display piece. It does include an AT-ST pilot minifigure but at 14.5 inches tall, it's much bigger than minifigure scale, which is why he'll stay perched next to the plaque.

It's posable to a degree; you can move the cockpit and peek inside it, but the legs are fixed; this is not a play-friendly set. If you're buying for children, consider instead this Lego Star Wars Smart Play Attack on Endor set. Yes, the AT-ST is a hilariously impractical vehicle, easily foiled by a gang of teddy bears, but that's half of its appeal.

Key features: 1,513 pieces, 14.5 × 8.5 × 8.5 in. / 37 × 22 × 22 cm, builders aged 18 or over.

Product launched: August 2025

Price history: Launched last year, this is the cheapest this set has ever been.

Price comparison: Amazon: $161 | Lego: $200 | Target: $172

Reviews consensus: The reviews from Lego and Amazon purchasers are almost universally positive, with people praising how fun it is to build and how fantastic it looks when finished.

✅ Buy it if: You want to build a stunning, detailed display model of Return of the Jedi's iconic vehicle.

❌ Don't buy it if: You want a playset. Despite the minifigure, this is purely a display model.
