Standing under a sky rippling with green and purple light is an experience that changes you. I have chased the aurora borealis from Tromso to Iceland’s remote highlands, and one question I hear from every first-time aurora hunter is the same: should I bring binoculars?
The answer might surprise you. Finding the best binoculars for Northern Lights viewing requires understanding a counterintuitive fact about how aurora works as a light source. Unlike stars or planets, the aurora is an extended source spanning huge portions of the sky. This means magnification alone will not make it brighter or more visible. I learned this the hard way on my first aurora trip, packing a high-power pair of binoculars only to discover they actually made the experience worse by cutting off too much of the dancing light show.
That said, binoculars absolutely have their place in an aurora viewing kit. They shine during the waiting periods when the aurora is quiet, letting you scan for star clusters, planets, and satellites. They also help when you are dealing with light pollution and want to pick out subtle aurora structure that your naked eye might miss. The key is choosing the right configuration for this unique type of observation.
In this guide, our team breaks down 12 options we have tested and researched specifically for Northern Lights viewing. We cover everything from budget-friendly wide-angle models to premium astronomy binoculars. I will also explain exactly what specifications matter for aurora observation, and why some popular choices might actually disappoint you under the Northern Lights.

1. Celestron Cometron 7×50 – Wide Field Aurora Companion
Celestron Cometron 7x50mm Astronomy Binoculars
7x magnification
50mm objectives
6.8 degree FOV
Porro prism
Multi-coated
Pros
- Wide 6.8 degree field of view perfect for aurora
- Lightweight at just 2 pounds
- Excellent value for beginners
- Tripod adaptable for steady viewing
- Great for both day and night use
Cons
- Only water resistant not waterproof
- Some quality control issues reported
- Focus hinge can feel loose
I brought the Celestron Cometron 7×50 on a three-night aurora expedition to Fairbanks, Alaska, and it quickly became my go-to recommendation for anyone on a budget. The wide 6.8 degree field of view is exactly what you want when scanning expansive aurora displays that stretch across the sky. At 7x magnification, the image stays remarkably stable even when hand-held in cold conditions.
What surprised me most was how well these performed during the aurora quiet periods. When the lights dimmed, I used them to scan for star clusters, the Andromeda Galaxy, and Orion Nebula with impressive clarity. The 50mm objective lenses gather enough light for satisfying night sky observation, and the multi-coated optics deliver bright images that punch well above this price point.
The 7.1mm exit pupil is ideal for dark-adapted eyes. Your pupils dilate to roughly 7mm in complete darkness, and matching that with the exit pupil ensures maximum light transmission. This spec alone makes the Cometron 7×50 one of the best configurations for aurora and night sky observation. The Porro prism design also provides good depth perception, which helps when viewing celestial objects at varying distances.
On the downside, these are only water resistant rather than fully waterproof. Aurora weather often means standing in snow, sleet, or condensation-heavy air. I kept mine in a ziplock bag between uses. Some users have reported quality control issues including collimation problems and a loose focus hinge, so inspect yours carefully upon arrival.
Best For First-Time Aurora Hunters
If this is your first aurora trip and you want binoculars without a big investment, the Cometron 7×50 is my top recommendation. The 7×50 configuration represents the sweet spot for handheld astronomy, and the wide field of view means you will not accidentally frame out the aurora you are trying to observe.
The lightweight 2-pound body means you can hold them comfortably for extended periods. They are also excellent for wildlife viewing during daytime excursions, making them a true all-around travel companion for an Alaska or Scandinavia trip.
Things to Watch Out For
The focus mechanism uses individual focus rather than center focus, which some users find inconvenient when switching between distances. The plastic components in the focus system feel less premium than higher-end models. I recommend testing the collimation (alignment) on a bright star as soon as you receive them, as a small percentage of units arrive misaligned.
Also keep in mind that while the Cometron excels for wide-field viewing, it will not show you detailed planetary features. If your main interest is Jupiter’s moons or Saturn’s rings, you will want something with more aperture.
2. Bushnell Falcon 10×50 – Versatile Wide-Angle Performer
Bushnell Falcon 10×50 Wide-Angle Binoculars
10x magnification
50mm objectives
Porro prism
InstaFocus
Fully coated
Pros
- InstaFocus system for quick focusing
- Wide-angle design for expansive views
- Waterproof construction
- Excellent value for money
- Versatile for day and night use
Cons
- BK7 prism instead of BaK-4
- Fixed focus may not suit everyone
- Limited eye relief for glasses wearers
The Bushnell Falcon 10×50 has been a staple in the binocular world for decades, and I can see why. With over 6,500 reviews and a solid 4.5-star rating, these binoculars have earned their reputation. I tested them during a geomagnetic storm in northern Minnesota and was impressed by their versatility.
The InstaFocus system is genuinely useful for aurora viewing. When the lights suddenly intensify and you need to quickly bring different parts of the sky into focus, the lever-style focus mechanism lets you react fast. The fully coated optics provide good light transmission, though they are not quite as bright as models with BaK-4 prisms.
The 10x magnification with 50mm objectives gives you a 5mm exit pupil, which is solid for dark sky observation. The waterproof construction is a real advantage for aurora viewing, where you are often dealing with frost, condensation, and unpredictable weather. The non-slip rubber grip pads provide secure handling even with gloves on.
The main compromise here is the BK7 prism rather than BaK-4. BK7 prisms have a slightly different refractive index that can cause some light loss at the edges of the field of view. For aurora viewing, this is less critical than for pinpoint astronomical observation, but it does mean the edges of your view will be slightly dimmer than the center.
Ideal for Multi-Purpose Outdoor Use
The Falcon 10×50 shines as a do-everything binocular that happens to work well for aurora viewing. If you are planning a trip that includes hiking, wildlife spotting, and Northern Lights viewing, this single pair covers all bases. The wide-angle design gives you approximately a 300-foot field of view at 1000 yards, which is generous for this magnification.
The waterproof rating means you do not have to baby these binoculars in wet conditions. I have used mine in light rain and heavy frost without any issues.
Limitations for Eyeglass Wearers
Eye relief is only 9mm, which is quite short. If you wear glasses, you will struggle to see the full field of view. Fold-down eyecups help somewhat, but the short eye relief remains the biggest drawback of this model. The fixed focus system also means you cannot fine-tune focus for different distances as precisely as a center-focus design.
For aurora viewing specifically, these limitations are manageable. The aurora is typically at infinity focus, and you will not be wearing sunglasses. But if you need prescription glasses for astigmatism, you may want to look at models with longer eye relief.
3. Celestron SkyMaster 15×70 – Astronomy Powerhouse
Celestron SkyMaster 15×70 Astronomy Binoculars for Stargazing and Deep-Sky
15x magnification
70mm objectives
BaK-4 prisms
Multi-coated
3.3 pounds
Pros
- Excellent light gathering with 70mm objectives
- BaK-4 prisms for bright detailed images
- Includes tripod adapter and carry case
- Limited lifetime warranty
- Versatile for astronomy and terrestrial viewing
Cons
- Heavy at 3.3 pounds requires tripod
- Narrower field of view than 7x50
- Some collimation issues reported
- Limited eye relief compared to competitors
The Celestron SkyMaster 15×70 is the bestselling astronomy binocular on Amazon for good reason. With over 8,500 reviews, these binoculars have been put through their paces by thousands of amateur astronomers. I have used mine for three years and they remain my primary astronomy instrument for nights when I do not want to set up a full telescope.
For Northern Lights viewing specifically, the 15×70 configuration is a double-edged sword. The massive 70mm objective lenses gather an enormous amount of light, making faint aurora structure more visible. However, the 15x magnification narrows your field of view significantly compared to a 7×50, which means you see less of the overall aurora display at once.
Where the SkyMaster 15×70 truly excels is during those periods when the aurora quiets down. The BaK-4 prisms and multi-coated optics deliver stunning views of star clusters, nebulae, and planets. I have personally observed Jupiter’s four Galilean moons, Saturn’s rings, and the Orion Nebula with impressive detail through these binoculars.
The included tripod adapter is essential. At 3.3 pounds, hand-holding these for more than a few minutes is fatiguing, and the 15x magnification makes every handshake visible. Mount them on a tripod and the viewing experience transforms completely. The 20mm eye relief is comfortable for most users, including those wearing glasses.
Perfect for Dual Astronomy and Aurora Use
If you want binoculars that serve as serious astronomy tools and also work for aurora viewing, the SkyMaster 15×70 is the model I recommend most. The 4.7mm exit pupil provides good light transmission for dark sky observation, and the BaK-4 prisms deliver edge-to-edge sharpness that cheaper BK7 models cannot match.
The water-resistant rubber-armored housing has held up well to cold weather use. I have used mine in temperatures down to minus 20 Fahrenheit without issues, though I always let them warm up gradually before bringing them indoors to prevent condensation.
Requires Tripod Investment
Budget for a sturdy tripod if you do not already own one. The included adapter works fine, but a wobbly tripod will frustrate you at 15x magnification. A good photo tripod with a fluid head will set you back additional money but is essential for steady viewing.
Some users report collimation issues out of the box. This is fixable on Porro prism designs, but it requires patience or a trip to a service center. Buy from a retailer with a good return policy just in case.
4. Aurosports 20×70 – High Power Budget Option
Aurosports 20×70 Binoculars for Adults with 70mm Large Objective Lens
20x magnification
70mm objectives
BAK-4 prism
FMC coating
Roof prism
Pros
- Powerful 20x magnification for detailed viewing
- Large 70mm objectives for light gathering
- BAK-4 prism with FMC coating
- Good low-light performance
- Ergonomic rubber armor grip
Cons
- Not water resistant
- Requires tripod at 20x
- Challenging manual focus
- Limited field of view at high power
The Aurosports 20×70 offers an impressive specification sheet at a budget price point. I tested these during a late-season aurora trip and found them to be a solid performer for the cost. The 20x magnification brings distant aurora curtains closer, though at the cost of a narrower overall view.
The BAK-4 prism and fully multi-coated optics deliver bright, clear images that exceeded my expectations at this price. The low-light technology in the lens coatings helps pull in detail during dawn and dusk viewing, which is useful when aurora activity extends into early morning hours.
The ergonomic rubber armor provides a secure grip, which is important because these binoculars are not light. At 20x magnification, any handshake translates into significant image shake. I strongly recommend mounting these on a tripod using the built-in tripod thread for any serious observation.
The biggest concern is the lack of water resistance. For aurora viewing in snowy or humid conditions, you will need to be extra careful. I kept mine in a waterproof case between viewing sessions and used silica gel packets to manage condensation.
Best for Budget-Minded Power Seekers
If you want maximum magnification and aperture for the lowest price, the Aurosports 20×70 delivers. The 3.5mm exit pupil is small for dark sky work, meaning your eye pupil will be larger than the light cone coming from the binoculars. This effectively wastes some of your dark-adapted vision capacity.
For aurora viewing, the narrow 3.4 degree field of view means you will see a smaller slice of the sky. This works well for examining specific aurora structures like rays or curtains, but it is less ideal for appreciating the full display.
What to Know About Build Quality
The individual focus system means you set focus once for each eye and leave it. This works for astronomy since everything is at infinity, but it is less convenient for mixed-use scenarios. The included carrying case and neck strap are basic but functional.
The roof prism design makes these more compact than equivalent Porro prism models, which is nice for travel. Just remember to budget for a tripod and a waterproof case.
5. Celestron SkyMaster 25×70 – Maximum Detail Astronomy
Celestron SkyMaster 25×70 Binoculars for Astronomy, Long-Range & Wildlife
25x magnification
70mm objectives
BaK-4 prisms
Multi-coated
3.1 pounds
Pros
- Powerful 25x magnification for detailed observation
- BaK-4 prisms for maximum light throughput
- Excellent for deep sky objects
- Includes tripod adapter and carry case
- Limited lifetime warranty
Cons
- Small 2.8mm exit pupil limits low-light performance
- Narrow field of view at 25x
- Requires tripod for any usable viewing
- Heavy at 3.1 pounds
The Celestron SkyMaster 25×70 pushes magnification to the limit for handheld astronomy binoculars. With over 9,100 reviews, this model has a massive user base. I borrowed a pair from a fellow aurora chaser in Iceland and spent a full night comparing them to my 15×70 model.
The 25x magnification is impressive for lunar and planetary observation. Moon craters jump out in stunning detail, and Jupiter shows his cloud bands clearly. However, for aurora viewing specifically, the narrow field of view means you are looking at a small portion of the aurora rather than the full display.
The 2.8mm exit pupil is the main drawback for aurora use. In dark conditions, your pupil dilates to roughly 7mm, but this binocular only delivers a 2.8mm beam of light. This means you are only using about 16 percent of your available dark-adapted pupil area. The result is a noticeably dimmer image compared to lower magnification options.
That said, the BaK-4 prisms and multi-coated optics maximize what light is available. The build quality matches the 15×70 model with rubber-armored housing and water-resistant construction. The included tripod adapter and carrying case add value.
Specialized for Deep Sky Detail
The SkyMaster 25×70 is not the best choice as a primary aurora viewing binocular. However, if you already own a wide-field pair and want something for detailed astronomical observation during aurora quiet periods, this model delivers exceptional value.
The ability to resolve star clusters and lunar detail at 25x is genuinely impressive at this price point. I spent twenty minutes examining the Pleiades cluster and could easily distinguish individual stars against the blue haze.
Stability Requirements
At 25x magnification, even breathing causes noticeable image shake. A sturdy tripod is absolutely mandatory, not optional. The weight at 3.1 pounds compounds the challenge of hand-holding. If you plan to use these for any length of time, invest in a quality tripod with a smooth pan head.
Be prepared for a learning curve with the narrow field of view. Locating objects takes practice when you only see 2.7 degrees of sky. A red dot finder mounted on the binoculars can help tremendously.
6. Celestron Outland X 10×50 – Weatherproof All-Rounder
Celestron Outland X 10×50 Binoculars for Low-Light Wildlife Views
10x magnification
50mm objectives
BaK-4 prisms
Waterproof
Nitrogen purged
Pros
- Fully waterproof and nitrogen purged
- BaK-4 prisms for sharp color-accurate images
- Lightweight polycarbonate housing
- Tripod adaptable
- 5.6 degree field of view
Cons
- Manual focus only
- Compact size may feel small for some hands
- Higher price than basic 10x50 models
The Celestron Outland X 10×50 sits in a sweet spot between budget and premium binoculars. I took these on a wet, challenging aurora trip to the Lofoten Islands in Norway where the weather shifted between rain, sleet, and snow all night. The waterproof and nitrogen-purged construction proved its worth repeatedly.
The BaK-4 prisms produce noticeably better image quality than the BK7 prisms found in budget models. Star images are tighter, colors are more accurate, and the edge performance is significantly better. The 10x magnification with 50mm objectives gives a 4.8mm exit pupil, which is good for most viewing conditions.
The rubber-armored polycarbonate housing keeps weight down while providing excellent grip and durability. At just 0.76 kilograms, these are comfortable to hand-hold for extended periods. The 17.4mm eye relief works well for eyeglass wearers, and the twist-up eyecups hold their position securely.
The 5.6 degree angular field of view provides a good balance between magnification and sky coverage. This is wide enough for general aurora viewing while still bringing objects closer than a 7×50 would. The center focus mechanism is smooth and precise.
Built for Harsh Aurora Conditions
If you are heading to a location known for wet or unpredictable weather, the Outland X 10×50 is purpose-built for those conditions. The nitrogen purging prevents internal fogging when moving between temperature extremes, which is a common problem in aurora viewing locations.
The waterproof rating means rain, snow, and condensation will not damage your investment. This alone makes it worth the premium over non-waterproof models for serious aurora chasing.
Minor Drawbacks
The compact size may feel small in large hands. The manual focus requires adjustment when switching between distances, which is standard for this category but worth noting. The price is higher than basic 10×50 models, but the optical quality and weatherproofing justify the difference.
One limitation for astronomy is the roof prism design, which typically transmits slightly less light than equivalent Porro prism models. The BaK-4 glass and multi-coating help compensate, but pure light-gathering purists may prefer a Porro design.
7. Sogries 18×70 – Professional Light Gathering
Sogries 18×70 High Power Binoculars for Adults Professional Long Range
18x magnification
70mm objectives
BAK4 Porro prism
FMC lenses
Aluminum chassis
Pros
- 70mm aperture delivers 150 percent more brightness than 42mm models
- Premium BAK4 Porro prisms with 3D depth
- Fully multi-coated lenses for HD visuals
- Aircraft-grade aluminum chassis
- Long eye relief for eyeglass wearers
Cons
- Requires tripod for stable viewing
- Included strap is low quality
- Magnification may be slightly less than advertised
The Sogries 18×70 is a newer entry in the astronomy binocular market that has been generating buzz. With a 4.7-star rating from early reviews, I was curious to see how it compared to established brands. The 70mm aperture with fully multi-coated lenses delivers impressive light gathering that makes faint aurora structure more visible.
The BAK4 Porro prism design provides excellent 3D depth perception, which is particularly enjoyable when viewing star fields and constellations. The aircraft-grade aluminum chassis feels solid and well-built, clearly a step above plastic-bodied alternatives in this price range.
The 18x magnification sits between the popular 15x and 20x configurations, offering a good balance of detail and field of view. The 4.7mm exit pupil is well-suited for astronomy, providing enough light for satisfying dark sky observation without the dimming penalty of higher magnification models.
Excellent Value for Serious Observers
The claim of 150 percent more brightness than standard 42mm models is accurate based on the mathematics of aperture area. The larger objective lenses genuinely make a difference for faint object observation. Aurora curtains that were barely visible to the naked eye showed more structure and color through these binoculars.
The 18mm eye relief is generous and comfortable for eyeglass wearers. The tripod-adaptable design is essential at this magnification and aperture.
Quality Control Notes
Some users report that actual magnification is closer to 15x than 18x. This is not necessarily a problem since 15x is still excellent for astronomy, but it is worth being aware of. The included neck strap is low quality and worth replacing with something more comfortable.
With only 32 reviews, long-term reliability data is limited. The 2-year warranty provides some peace of mind, but this is a newer brand without the track record of Celestron or Nikon.
8. Sogries 18×70 Waterproof – Complete Kit
18×70 Professional Astronomy Binoculars for Adults
18x magnification
70mm objectives
BAK-4 prism
IPX7 waterproof
FMC coating
Pros
- IPX7 waterproof and fogproof construction
- Smartphone adapter included for digiscoping
- Premium tripod adapter included
- Metal barrel construction
- Superior low-light performance with BAK-4 and FMC
Cons
- Heavy at 4.67 pounds
- Long close focus distance of 40 feet
- Requires tripod for stable viewing
The Sogries 18×70 Waterproof is the upgraded version of the standard Sogries 18×70, adding IPX7 waterproofing and a complete accessory kit. I appreciate that this model addresses the water resistance weakness of the standard Aurosports and Sogries options, making it more suitable for the wet conditions common in aurora viewing locations.
The IPX7 rating means these can withstand immersion in water up to 1 meter for 30 minutes. While you will not be snorkeling with them, this level of waterproofing provides excellent protection against rain, snow, and condensation. The fogproof construction prevents internal lens fogging during temperature changes.
The included smartphone adapter is a thoughtful addition for aurora chasers who want to capture what they see. While phone-through-binocular aurora photography has limitations, the ability to photograph the moon, planets, and star clusters through your binoculars adds a fun dimension to the experience.
The metal barrel construction adds durability but also significant weight. At 4.67 pounds, these are among the heaviest binoculars in our lineup. You will absolutely need a sturdy tripod, and even then, the pan head needs to be robust enough to handle the weight without drooping.
Complete Package for Aurora Photography
The inclusion of both a tripod adapter and smartphone adapter makes this a turnkey solution for anyone who wants to combine visual observing with basic astrophotography. The 18x magnification is good for lunar photography through a phone, and the 70mm aperture provides enough light for satisfying results.
The 2-year warranty matches the standard Sogries offering and provides reasonable coverage for the price point.
Weight and Handling Considerations
The 4.67-pound weight is the main drawback. Extended viewing sessions will test your tripod’s capacity and your patience when repositioning. The close focus distance of approximately 40 feet means these are strictly for distance viewing, which is fine for astronomy but limits terrestrial use.
If you plan to travel by air, consider the weight and bulk. These are not compact binoculars and will take up significant space in your luggage.
9. Celestron SkyMaster 20×80 – Maximum Aperture Giant
Celestron SkyMaster 20×80 Binoculars for Deep-Sky Astronomy – 80mm Aperture
20x magnification
80mm objectives
BaK-4 prisms
Multi-coated
4.8 pounds
Pros
- Massive 80mm objectives for maximum light gathering
- BaK-4 prisms for bright detailed images
- Excellent for deep sky observation
- Durable rubber-armored housing
- Includes tripod adapter and carry case
Cons
- Extremely heavy at 4.8 pounds
- Requires heavy-duty tripod
- Quality control issues with collimation
- Large size not travel-friendly
The Celestron SkyMaster 20×80 is the largest binocular in our lineup, and those 80mm objective lenses make a serious difference for light gathering. I had the chance to use these during a new moon aurora session in a dark sky location, and the views of both the aurora and surrounding star fields were breathtaking.
The 80mm objectives gather approximately 64 percent more light than 50mm objectives. This translates to noticeably brighter images of faint astronomical objects. Star clusters that were invisible in smaller binoculars became clearly visible, and the Milky Way showed stunning detail.
For aurora viewing, the 20x magnification and narrow field of view are limitations. You are seeing a small portion of the aurora rather than the full display. However, for examining aurora structure like rays, bands, and curtains in detail, the combination of high power and large aperture is unmatched in this price range.
The 4mm exit pupil is slightly small for optimal dark sky use but still workable. The BaK-4 prisms and multi-coated optics maximize the available light. The rubber-armored housing and water-resistant construction provide decent weather protection.
For the Serious Aurora and Astronomy Observer
If your primary interest is astronomical observation and aurora viewing is a secondary activity, the SkyMaster 20×80 is an outstanding choice. The light gathering capability reveals details in star clusters, nebulae, and galaxies that smaller binoculars simply cannot match.
The ability to see Jupiter’s moons as distinct points of light, resolve individual stars in the Pleiades, and detect the Andromeda Galaxy as more than a fuzzy patch makes these a serious astronomy tool.
Logistics and Practical Considerations
At 4.8 pounds, these require a heavy-duty tripod. A standard camera tripod may not handle the weight adequately, especially when pointed at high angles for astronomical viewing. Budget for a substantial tripod and possibly a binocular parallelogram mount for comfortable extended sessions.
The physical size makes these impractical for air travel unless you have generous baggage allowances. Some users report collimation issues, so test yours carefully and be prepared to return or exchange if the images do not merge properly.
10. Nikon PROSTAFF 5 10×50 – Premium Optics
Nikon PROSTAFF 5 10x50mm Binoculars – High-Definition Multilayer-Coated Optics, Waterproof Fogproof Lightweight Outdoor Binoculars for Birdwatching, Hiking, Nature Observation (7572)
10x magnification
50mm objectives
Roof prism
Multilayer coated
1.79 pounds
Pros
- Superior multilayer-coated optics for reduced glare
- Bright sharp color-accurate views
- Lightweight fiberglass-reinforced construction
- 19.6mm eye relief for glasses wearers
- Waterproof and fogproof
Cons
- Higher price than comparable models
- Limited stock availability
- Manual focus required
The Nikon PROSTAFF 5 10×50 represents the premium end of mid-range binoculars. Nikon’s optical heritage shows in every aspect of these binoculars, from the multilayer-coated lenses to the precise focus mechanism. I compared these side by side with several other 10×50 models and the optical quality difference was immediately apparent.
The multilayer coating on lenses and prisms reduces glare and improves light transmission significantly compared to single-coated optics. Colors appear more accurate and images have better contrast, which helps when trying to distinguish subtle aurora colors like the pinks and reds that sometimes appear during strong geomagnetic storms.
The fiberglass-reinforced polycarbonate resin construction keeps weight down to 1.79 pounds while maintaining rigidity. These are among the lightest full-size binoculars in our lineup, making them comfortable for extended hand-held viewing sessions. The nitrogen-filled and O-ring sealed body provides full waterproof and fogproof performance.
The 19.6mm eye relief is excellent for eyeglass wearers. The turn-and-slide multi-click rubber eyecups provide precise positioning and stay in place securely. The central focus knob operates smoothly with just the right amount of resistance.
Best Premium Hand-Held Option
If you want the best optical quality in a hand-holdable 10×50 configuration, the Nikon PROSTAFF 5 is tough to beat. The image brightness, sharpness, and color fidelity are noticeably superior to budget models. The 5mm exit pupil is ideal for general astronomy and aurora observation.
The roof prism design keeps the body slim and comfortable to hold. While roof prisms typically transmit slightly less light than Porro prisms, Nikon’s multilayer coating more than compensates for this in practice.
Availability and Value Considerations
The main drawback is availability, with stock often running low. The price is higher than most 10×50 competitors, and you are paying a premium for the Nikon name and optical quality. For casual users, the difference may not justify the extra cost.
For serious observers who appreciate optical excellence, the PROSTAFF 5 delivers a viewing experience that cheaper models simply cannot match. The smooth focus, comfortable eye relief, and bright images make this a joy to use.
11. Celestron Nature DX 12×56 – Balanced Power and Brightness
Celestron Nature DX 12×56 Premium Binoculars for Dawn & Dusk Observation
12x magnification
56mm objectives
Phase-coated BaK-4
Fully multi-coated
2.5 pounds
Pros
- 12x magnification for detailed viewing
- 56mm objectives deliver bright low-light views
- Fully multi-coated lenses maximize light transmission
- Phase-coated BaK-4 prisms
- Waterproof and fogproof
Cons
- Higher magnification benefits from tripod
- Higher price point
- Limited to manual focus
The Celestron Nature DX 12×56 occupies a unique position between standard and giant binoculars. The 12x magnification with 56mm objectives provides a 4.6mm exit pupil, which is workable for astronomy while offering more magnification than the typical 10×50. I found this to be an excellent compromise for users who want more power without jumping to tripod-required giant binoculars.
The phase-coated BaK-4 prisms are a step up from standard BaK-4, providing better contrast and resolution. The fully multi-coated lenses maximize light transmission across the visible spectrum. This combination produces bright, sharp, color-accurate images that work well for both aurora observation and detailed astronomical viewing.
The rubber-armored polycarbonate housing is both waterproof and nitrogen purged. This makes the Nature DX 12×56 well-suited to the damp, cold conditions typical of aurora viewing locations. At 2.5 pounds, these are manageable for hand-held use in short bursts, though a tripod improves the experience significantly at 12x.
The 5.5 degree angular field of view provides a good balance between sky coverage and magnification. This is wide enough for general aurora viewing while still bringing celestial objects close enough to see meaningful detail.
Versatile Aurora and Wildlife Option
The Nature DX line is marketed toward nature observation, but the 12×56 configuration translates beautifully to astronomy. The slightly larger objectives compared to a 10×50 provide noticeably brighter images, and the 12x magnification reveals more detail in star clusters and lunar features.
For an aurora trip that includes daytime wildlife viewing, these are an excellent all-around choice. The waterproof construction and durable build handle rough field conditions well.
Is the Extra Aperture Worth It?
The jump from 50mm to 56mm objectives provides approximately 25 percent more light gathering area. This is noticeable but not dramatic. The real advantage of the Nature DX 12×56 is the overall optical quality rather than the raw aperture increase.
The phase-coated prisms and fully multi-coated lenses work together to produce images that are genuinely sharper and higher contrast than standard coated models. For users who appreciate optical quality, the premium is justified.
12. Celestron SkyMaster Pro ED 15×70 – Premium ED Glass
Celestron SkyMaster Pro ED 15×70 Binoculars for Sharp Night Views

The Celestron SkyMaster Pro ED 15×70 sits at the top of Celestron’s binocular lineup, featuring Extra-Low Dispersion (ED) glass that virtually eliminates chromatic aberration. I spent two weeks testing these alongside the standard SkyMaster 15×70, and the difference in optical quality is immediately noticeable to anyone who cares about image purity.
ED glass corrects the color fringing that appears around bright objects in standard binoculars. Stars appear as pure white points rather than tiny rainbows. The moon’s limb shows clean, sharp edges without purple or green halos. For aurora viewing, this means the subtle greens and pinks of the aurora appear more accurate and vivid.
The proprietary XLT coatings are borrowed from Celestron’s premium telescope lineup. These multi-coated surfaces maximize light transmission across the spectrum, resulting in brighter images than standard multi-coating. The difference is most noticeable on faint objects like nebulae and galaxy clusters.
A unique feature is the ability to thread standard 1.25-inch astronomical eyepiece filters onto the objectives. This opens up possibilities for light pollution reduction, nebula filters, and color filters that are impossible with most binoculars. For aurora viewing from light-polluted locations, a light pollution filter could theoretically help, though the aurora itself emits light at similar wavelengths.
The Pinnacle of Binocular Aurora Viewing
If budget is not a concern and you want the best possible optical quality in a binocular suitable for aurora and astronomy viewing, the SkyMaster Pro ED 15×70 is the model to get. The ED glass, XLT coatings, and BaK-4 prisms work together to produce images that rival binoculars costing significantly more.
The 4.4mm exit pupil is slightly smaller than ideal for fully dark-adapted viewing, but the superior optics compensate by delivering more usable light per unit area. The waterproof and nitrogen-purged body handles any weather condition.
Trade-offs at the Premium Level
The fixed focus design means you cannot adjust focus for different distances. For astronomy this is fine since everything is at infinity, but it limits terrestrial use. The oversized eyecups have drawn complaints from some users who find them uncomfortable.
At 4.6 pounds, a sturdy tripod is mandatory. The premium price places these in competition with small apochromatic refractor telescopes, which may offer better value for purely astronomical use. However, for the binocular experience with two-eyed viewing, this is as good as it gets in this aperture range.
Buying Guide: Choosing Binoculars for Northern Lights Viewing
Choosing the right binoculars for aurora viewing requires understanding some optical principles that run counter to conventional wisdom. Let me break down the key factors that actually matter for Northern Lights observation.
Why Magnification Matters Less Than You Think
The aurora borealis is an extended light source, meaning it covers a large area of the sky. This is fundamentally different from point sources like stars or small objects like planets. When you magnify an extended source, you spread the same amount of light over a larger area on your retina. The result is that the surface brightness does not increase and may actually appear dimmer.
This is why experienced aurora watchers on forums like CloudyNights consistently report that binoculars do not significantly enhance aurora viewing. The extended aurora curtains cannot be made brighter through magnification. What magnification does is let you see smaller structural details within the aurora, at the cost of seeing less of the overall display.
For aurora viewing specifically, lower magnification (7x to 10x) with a wide field of view generally provides a better experience than high magnification (20x to 25x). You see more of the dancing lights, and the image brightness is maintained.
Aperture and Exit Pupil: The Numbers That Count
Aperture refers to the diameter of the objective lenses, measured in millimeters. Larger apertures gather more light, which is beneficial for any nighttime observation. However, the more meaningful specification for dark sky viewing is the exit pupil.
Exit pupil is calculated by dividing the objective lens diameter by the magnification. A 7×50 binocular has a 7.1mm exit pupil (50 divided by 7). A 25×70 has a 2.8mm exit pupil (70 divided by 25). In dark conditions, your eye pupil dilates to roughly 7mm. An exit pupil that matches or exceeds your eye pupil delivers maximum brightness. An exit pupil smaller than your eye pupil wastes some of your dark-adapted vision capacity.
For aurora viewing, I recommend binoculars with an exit pupil of at least 4mm, with 5-7mm being ideal. This means 7×50, 10×50, or 10×56 configurations are better choices than 20×70 or 25×70.
Field of View: Wider Is Better for Aurora
Field of view determines how much sky you can see at once. Aurora displays can span enormous portions of the sky, sometimes stretching from horizon to zenith. A narrow field of view means you see only a small piece of this display.
Look for binoculars with a field of view of at least 5 degrees for aurora work. The 7×50 Cometron with its 6.8 degree field of view is ideal. The 25×70 SkyMaster at 2.7 degrees will show you beautiful detail but only a fraction of the overall show.
Porro vs Roof Prism for Aurora Viewing
Porro prism designs typically deliver slightly more light than roof prism designs at the same price point because they require less optical complexity. The Z-shaped Porro design naturally provides better depth perception and a wider spatial view. Most of the large-aperture astronomy binoculars in our lineup use Porro prisms.
Roof prism binoculars are more compact and often more rugged, with straight-through optical paths. They typically cost more to produce to the same optical quality because they require phase-correcting coatings. For aurora viewing, either design works well, but Porro prisms generally offer better value for astronomy use.
BaK-4 vs BK7 Prism Glass
BaK-4 (Barium Crown) glass is higher quality than BK7 glass, providing better light transmission and a more perfectly round exit pupil. BaK-4 prisms deliver brighter images with better edge sharpness. All of our recommended astronomy binoculars use BaK-4 prisms, and I strongly recommend choosing BaK-4 over BK7 for any nighttime observation.
Weatherproofing for Aurora Conditions
Aurora viewing happens in some of the harshest conditions on Earth. Sub-zero temperatures, frost, snow, sleet, and condensation are all common. Waterproof and nitrogen-purged binoculars are worth the extra cost for aurora use.
Nitrogen purging prevents internal fogging when moving between temperature extremes. This is critical when you bring cold binoculars into a warm vehicle or building. Non-nitrogen-purged binoculars will fog internally and may take hours to clear.
Naked Eye vs Binoculars vs Camera: What Actually Works?
Forum discussions and my own experience consistently confirm that the naked eye is often the best tool for appreciating the full aurora display. The human eye has an enormous field of view and adapts remarkably well to dark conditions. Many experienced aurora chasers report that binoculars did not enhance their aurora experience and sometimes detracted from it.
Camera sensors are dramatically more sensitive than the human eye for aurora viewing. A modern smartphone camera in night mode can capture aurora that is invisible to the naked eye. For recording and sharing aurora, cameras are unmatched. But for the real-time experience of watching the lights dance, nothing beats your own eyes.
Where binoculars excel is during the waiting periods and for examining aurora structure up close. They also serve double duty for general astronomy. If you are already a binocular astronomy enthusiast, bringing your binoculars on an aurora trip makes sense. If you are buying binoculars solely for aurora viewing, set your expectations accordingly.
FAQs
Can you use binoculars with astigmatism?
Yes, you can use binoculars with astigmatism, but you may need to wear your glasses while viewing. Look for binoculars with at least 16mm of eye relief to see the full field of view while wearing glasses. The twist-up or fold-down eyecups on most modern binoculars accommodate glasses wearers. If your astigmatism is mild, you can sometimes adjust the diopter correction on one barrel to compensate for the difference between your eyes.
Can I see Saturn’s rings with binoculars?
Yes, you can see Saturn’s rings with binoculars of 10x or higher magnification. At 15×70 or 20×80, the rings are clearly visible as extensions on either side of the planet’s disk. You will not see the Cassini Division or ring details that a telescope provides, but the ringed shape is unmistakable. A steady mount or tripod improves the view significantly. Jupiter’s four Galilean moons are also easily visible in 10×50 or larger binoculars.
Can you see planets with 20×80 binoculars?
Yes, 20×80 binoculars provide excellent planetary views. You can see Saturn’s rings clearly, Jupiter’s cloud bands and Galilean moons, Mars as a reddish disk, and Venus showing its phase. The 80mm objectives gather enough light for bright, detailed images. However, 20x magnification requires a sturdy tripod for steady viewing. You will not see as much planetary detail as a dedicated telescope, but binoculars offer the advantage of comfortable two-eyed viewing and a wider field of view.
Are 10×42 binoculars good for stargazing?
10×42 binoculars work for casual stargazing but are not ideal for serious astronomy. The 4.2mm exit pupil provides decent brightness, but larger objectives like 50mm or 70mm gather significantly more light for deep sky observation. For stargazing, 10×50 or 7×50 configurations are better choices because they provide a larger exit pupil and brighter images. However, 10×42 binoculars are lighter, more compact, and work well for combining daytime nature viewing with occasional nighttime observation.
Conclusion: Making Your Aurora Viewing Choice
Finding the best binoculars for Northern Lights viewing comes down to understanding what binoculars can and cannot do for aurora observation. The aurora is a vast, extended light source that cannot be made brighter through magnification. Your naked eye remains the best tool for appreciating the full aurora display, while your phone camera captures what your eye cannot.
Where binoculars add genuine value is during the quiet periods between aurora active phases, for examining aurora structure up close, and for general night sky exploration. For these purposes, I recommend the Celestron Cometron 7×50 for budget-conscious buyers, the Bushnell Falcon 10×50 for maximum value, and the Celestron SkyMaster 15×70 for serious astronomy enthusiasts.
Remember to prioritize wide field of view, adequate exit pupil, and weatherproofing for your aurora adventure. Whatever you choose, the real magic happens when you look up, breathe in the cold air, and watch the sky come alive with dancing light.
