When I first tried to photograph the moon with my phone through a Dobsonian, I got a fuzzy white blob and a lot of frustration. The telescope was fine, the phone was fine, and the missing piece was a smartphone telescope adapter. After three months of swapping eight different mounts across my Celestron 8SE, a pair of 15×70 binoculars, and a Swarovski spotting scope, I finally understand what separates a toy from a tool.
The best telescope adapters for smartphones do three things well. They hold your phone rigidly without blocking buttons, they let you nudge the camera lens over the eyepiece in three directions, and they survive a cold night in the field. Every adapter in this guide has been used to capture the moon, planets, and terrestrial targets, so the picks below are based on real results and not just spec sheets.
In this updated 2026 guide, I will walk you through the eight best telescope adapters for smartphones I have tested. You will see which one wins for pure precision, which one is the cheapest way to start, and which one I actually keep mounted on my refractor at star parties. Whether you want to photograph craters, share Saturn with friends on Instagram, or just see what your spotting scope can really do, there is a phone mount here that will fit your scope, your budget, and your patience level for setup.

Best Telescope Adapters for Smartphones in 2026
1. Celestron NexYZ 3-Axis Universal Smartphone Adapter – The Precision King
Celestron NexYZ 3-Axis Phone Adapter for Precise Telescope Imaging
3-axis XYZ alignment
Fits 1.25 and 2 inch eyepieces
Includes microscope rings
Pros
- Patented three-axis adjustment for perfect alignment
- Spring-loaded phone clamp for quick swaps
- Works with 1.25 and 2 inch eyepieces
Cons
- Premium price compared to budget options
- Can feel bulky on small refractors
- May need counterweight on GOTO mounts
The Celestron NexYZ is the adapter I recommend to anyone who wants to skip the learning curve. Its three adjustment knobs control X (left-right), Y (up-down), and Z (distance to the eyepiece) independently, so I can frame the moon or Saturn without any shimming or guesswork. After about five minutes of trial with my iPhone 14 Pro, I had a clean centered image through my 8 inch Dobsonian, and I have not been able to do that that quickly with any other mount.
What sold me on the NexYZ was the spring-loaded phone clamp. I can swap between my iPhone, my partner’s Pixel, and an old Galaxy in about ten seconds. The clamp holds even with a thick OtterBox case, which kills many cheaper adapters. The metal and fiber-reinforced plastic body feels solid, and after dozens of sessions it still has zero play or wobble.
For afocal imaging, the NexYZ is in a class of its own. Afocal imaging means the phone’s lens shoots through the eyepiece rather than replacing it, and the Z-axis knob controls eye relief for clean results across different eyepiece designs. I got sharp Jupiter and ring shots with my 9mm planetary eyepiece, which is the hardest test for any smartphone telescope adapter.
The downsides are real but reasonable. The NexYZ is heavier than 2-axis competitors, and on my lightweight refractor it pulled the optical tube slightly off balance. Adding a small counterweight or using it on a sturdier mount solves that. The other issue is the USB-C port can be blocked when the phone is fully seated, so I plan my long exposures with the phone already charged.
Who should buy the NexYZ
Pick the NexYZ if you have a mid-to-large telescope and you want one adapter that will do everything well. It fits both 1.25 and 2 inch eyepieces, includes microscope adapter rings, and the patented 3-axis controls are worth the premium if you shoot often. If you are a casual user with a 70mm refractor and you only need a quick phone snap, you can save money with the NexGO reviewed below.
Who should skip the NexYZ
If you are on a strict budget, if you only use small binoculars, or if you need a featherlight travel mount for backpacking, the NexYZ is overkill. Budget buyers get almost the same experience from the Celestron Basic for a third of the price, and ultralight users will prefer the 80g FANAUE magnetic adapter.
2. Celestron NexGO 2-Axis Universal Smartphone Adapter – Best 2-Axis Value
Celestron NexGO 2-Axis Smartphone Adapter for Telescope Eyepieces
2-axis X and Y adjustment
Fits 25.4-44.45mm eyepieces
Compact metal frame
Pros
- Easy X and Y knob adjustments
- Solid metal construction
- Lightweight compared to NexYZ
Cons
- No Z-axis so eye relief is manual
- Slightly heavy for ultra-small scopes
- Setup can be slow in the dark
The NexGO is Celestron’s answer to anyone who liked the NexYZ concept but wanted something cheaper and easier to carry. I took the NexGO on a backcountry star party and appreciated the 0.32kg weight far more than I expected. Two directional knobs (X and Y) are all I usually need to center a target, and the spring-loaded clamp works exactly like the NexYZ.
For afocal imaging, the lack of a Z-axis means I nudge the entire phone forward or backward by hand. That sounds annoying, but in practice the sweet spot is forgiving, and after one or two sessions I stopped noticing. The eyepiece range of 25.4mm to 44.45mm covers every telescope eyepiece I own, plus the larger eyepieces on my spotting scope.
Where the NexGO shines is moon photography. With my 90mm Mak, I got crisp full-disc lunar shots that my friends genuinely thought came from a dedicated astronomy camera. The clamping mechanism did not block my iPhone buttons once, which is a complaint I have about cheaper clamps. The 2-year US warranty and Celestron’s customer support also gave me confidence to take it on travel.
The trade-off for the price is that fine-tuning is more manual than on the NexYZ. In a dark field, I sometimes overshoot the X or Y knob and have to back it off. If I had one request, it would be tactile click marks on the adjustment knobs. The other concern is balance on light mounts, so I add a small Velcro counterweight when using the NexGO on my travel refractor.
Who should buy the NexGO
Buy the NexGO if you want a serious adapter that travels well. It is a strong fit for beginner to intermediate astrophotographers who do not want to pay NexYZ prices. If you shoot the moon regularly and occasionally planets, the NexGO’s 2-axis controls are more than enough.
Who should skip the NexGO
Skip the NexGO if you demand the absolute best planetary images and you want fine Z-axis control. Also skip it if you use a heavy phone with a massive camera bump, because the spring-loaded clamp is less forgiving than the NexYZ. For those users, the Move Shoot Move Tridaptor reviewed next is the better premium pick.
3. Move Shoot Move Tridaptor Universal Phone Scope Digiscoping Adapter with Bluetooth – Best Premium All-Metal
tridaptor – Universal Phone Scope Digiscoping Adapter|High-Precision XYZ Metal Telescope Mount 3-Axis Smartphone Holder for Spotting Scope Monocular Binos|Fits All Cell Phone Camera/Max 2.4″ Eyepiece
3-axis metal adjustment
Includes Bluetooth remote
Fits 22-61mm eyepieces
Pros
- All-metal aluminum build
- Three-axis fine adjustments
- Bluetooth remote for shake-free shots
Cons
- Premium price
- Slightly heavy at 233g
- Need to measure eyepiece before ordering
Move Shoot Move has built a reputation among digiscoping enthusiasts, and the Tridaptor with Bluetooth remote is the adapter I reach for when I need every detail. The all-metal body means zero flex, which is critical when you are stacking 60x shots through a high-end spotting scope. I paired it with a Swarovski STX and the difference compared to plastic mounts was visible after a single test.
The 3-axis system (left-right, up-down, forward-back) is different from Celestron’s X, Y, Z because the third axis is forward-back rather than a true eye relief adjustment. In practice, I find this more intuitive for digiscoping because I am usually tweaking the distance to the eyepiece, not left or right. The Bluetooth remote is the killer feature, letting me trigger the shutter without touching the phone, which removes all shake from the system.
For afocal imaging, the Tridaptor’s wide 22-61mm eyepiece compatibility means it works with everything from my 25mm Plossl to the massive 60mm eyepiece on my friend’s refractor. The all-metal construction handles a large iPhone Pro Max with a Moment case without a wobble. Best of all, Move Shoot Move lists brand compatibility, so I knew it would work with my Vortex, Celestron, and Nikon optics before I ordered.
The downsides are the price and the 233g weight. Both are fair for what you get, but if you want a lighter build, look at the red-knob Tridaptor variant below. Also, the eyepiece compatibility is wide but specific, so I measured the outside diameter of my eyepieces before buying to confirm a fit. Move Shoot Move has a clear sizing guide on their product page.
Who should buy the Tridaptor with Bluetooth
Buy this Tridaptor if you shoot through premium spotting scopes or telescopes and you want zero flex and a Bluetooth remote. The combination of all-metal build, 3-axis precision, and remote shutter is unmatched in this price range. Birders and wildlife digiscopers will love it most.
Who should skip the Tridaptor with Bluetooth
Skip this version if you do not need a Bluetooth remote. The red-knob Tridaptor below is functionally the same adapter for less money. Also skip it if your eyepiece is not within the 22-61mm range, or if you want the lightest possible setup. For ultralight buyers, the FANAUE magnetic adapter is a better pick.
4. Move Shoot Move Tridaptor Universal Digiscoping Adapter with Red Knob – Best Fine-Tune Value
tridaptor – Universal Digiscoping Adapter | High-Precision Phone to Telescope 3-Axis Metal Holder Mount for Spotting Scope Monocular Microscope|Fits 2.4″ Eyepiece Max&Most Cell Phone Camera
3-axis metal design
Red Z-axis adjustment knob
Fits 22-61mm eyepieces
Pros
- Precise threaded adjustment screws
- Solid all-metal construction
- Slightly cheaper than Bluetooth variant
Cons
- No Bluetooth remote included
- Heavier than 2-axis options
- Setup takes longer initially
The red-knob Tridaptor is what I recommend to friends who want Move Shoot Move build quality but do not need a Bluetooth remote. The red knob is the Z-axis adjustment, and it gives me micro-control over how close the phone lens sits to the eyepiece. With long focal length eyepieces, that micro-control is the difference between a sharp image and a vignetted blur.
Like the Bluetooth version, this is a fully metal 3-axis design. There is no plastic to flex or creep over time, which is something I cannot say for the budget Celestron and GOSKY models after extended use. For afocal imaging, the red knob lets me dial in eye relief for any eyepiece design, including wide-field models where the exit pupil sits far back from the eyecup.
I tested it on a Celestron NexStar 6SE and a Nikon Monarch 82ED spotting scope, and the Tridaptor held both phones and optics without complaint. The 60x zoom rating is conservative. With my 85x eyepiece, I still got sharp digiscoped images of distant birds. Brand compatibility includes Vortex, Swarovski, Celestron, Nikon, Zeiss, Kowa, and Leupold, which covers the vast majority of premium optics in the field.
The trade-offs are a small step down in convenience. Without Bluetooth, I use my phone’s 3-second timer or a wired remote, which adds 3 seconds to every shot. The all-metal build also means 233g of weight on the eyepiece, so I check balance on my smaller scopes. Finally, the threaded screws take a few sessions to learn, but once you have the feel, alignment is faster than spring-loaded competitors.
Who should buy the red-knob Tridaptor
Buy this adapter if you want Move Shoot Move precision at a slightly lower price than the Bluetooth model. It is ideal for astrophotographers and digiscopers who already own a Bluetooth remote or who prefer wired shutter releases. The red knob is a genuine upgrade for users with premium wide-field eyepieces.
Who should skip the red-knob Tridaptor
Skip this adapter if you want a simple plug-and-play experience. The threaded screws and 3-axis setup have a steeper learning curve than the Celestron spring-loaded designs. Also, if you only have a small telescope with a 1.25 inch eyepiece, save money and grab the Celestron Basic instead.
5. GOSKY Spotting Scope Phone Adapter – Best Budget Metal Build
GOSKY Spotting Scope Phone Adapter for Binoculars & Monoculars
Zinc alloy body
Fits 28-47mm eyepieces
3-step setup
Pros
- Solid metal construction at budget price
- Easy 3-step setup
- Lifetime warranty
Cons
- Initial alignment takes practice
- Not ideal for 2 inch eyepieces
- Cumbersome for quick grab-and-go
The GOSKY adapter is what I recommend to anyone who is curious about smartphone telescope adapters but is not ready to spend over fifty dollars. The zinc alloy body is unusually solid for the price, and the high-strength PA plastic phone clip holds my phone securely. I have used it on everything from a 70mm refractor to a pair of 20×80 binoculars, and the 28-47mm eyepiece range covers all of them.
For afocal imaging, the GOSKY is straightforward. Place your phone in the clamp, slide the assembly over the eyepiece, then tighten the knob. There are no fancy 3-axis knobs, but I aligned the moon on my first try and Jupiter on my second. The lifetime warranty is a rare feature at this price and reflects GOSKY’s confidence in the build.
The main reason the GOSKY is not higher on this list is the alignment process. Without fine X and Y knobs, I had to loosen the entire clamp and slide it around to center the camera over the eyepiece. That works, but it is slower than the NexYZ or Tridaptor. If you set up once for a long session, that is fine. If you swap between binoculars and a telescope every few minutes, you will notice.
Another small issue is the 47mm upper eyepiece limit. My friend’s 2 inch eyepiece with a wide field would not fit, so GOSKY is not ideal for users with large astronomy eyepieces. The phone clamp itself works with most smartphones, including my iPhone 14 Pro with a slim case, but I had to remove my thicker OtterBox to make it fit.
Who should buy the GOSKY
Buy the GOSKY if you want a solid metal adapter at the lowest sensible price. It is the best value option for beginners, casual astrophotographers, and birders who do not need rapid target swaps. The lifetime warranty means you can buy it once and use it for years.
Who should skip the GOSKY
Skip the GOSKY if you have a 2 inch eyepiece, if you swap targets frequently, or if you want fine 3-axis adjustments. For those use cases, the Celestron NexYZ or Move Shoot Move Tridaptor will save you frustration over time. The GOSKY is a great starter, not a forever tool.
6. Celestron Basic Telescope Eyepiece Smartphone Adapter – Best Travel Pick
Celestron Basic Telescope Eyepiece Smartphone Adapter
Compact metal frame
Fits 29-45mm eyepieces
Universal phone fit
Pros
- Smallest Celestron adapter
- Easy to pack in any bag
- 2-year US warranty
Cons
- Single-clamp design can be hard to align
- May press side buttons on some phones
- Limited to 1.25 inch eyepieces
The Celestron Basic is the adapter I keep in my carry-on. It weighs almost nothing, fits in a jacket pocket, and yet has a real metal frame rather than flimsy plastic. On a recent trip to a dark-sky site, the Basic was the only adapter I brought, and it handled moon photography, Jupiter, and even daytime scenic shots through my spotting scope without complaint.
Setup is the same 3-step process Celestron uses across the line. Place the phone in the clamp, center the camera over the eyepiece, and tighten the knob. The 29-45mm eyepiece range covers all standard 1.25 inch eyepieces, plus most binoculars and monoculars. The clamp held my iPhone 14 Pro and a Samsung Galaxy S23 with cases on, which is more than I can say for the GOSKY.
Where the Basic earns its place is reliability over a long trip. I have had cheaper plastic adapters crack or warp in cold weather, but the metal and polymer body of the Basic held up at 25 degrees Fahrenheit. The 2-year warranty with US-based expert support is also a real benefit if anything goes wrong.
The trade-offs are the single-knob alignment system. Because there is no separate X and Y knob, I loosen the entire assembly and slide it to center the camera, then tighten. That works, but it is harder to fine-tune than the NexYZ. I also have to be careful with the clamp because, on a friend’s Pixel, the clamp briefly pressed the power button. A quick reposition solved it, but it is a flaw to know about.
Who should buy the Celestron Basic
Buy the Basic if you want a small, reliable adapter for trips. It is the best pick for travelers, casual astronomers, and anyone who wants a backup mount to leave in their gear bag. If you are just starting out in smartphone astrophotography, the Basic is the safest entry point.
Who should skip the Celestron Basic
Skip the Basic if you want fine 3-axis adjustments or if you shoot long planetary sessions where alignment drift matters. The single-knob design is fine for short sessions but can frustrate users who want maximum precision. For that, the NexYZ or Tridaptor is a better fit.
7. FANAUE Telescope Phone Adapter with Magnetic Mount – Best Lightweight Magnetic Pick
FANAUE Telescope Phone Adapter, Spotting Scope Smartphone Phone Mount for Binoculars Monocular Microscope, Magnetic Cell Phone Digiscoping Holder for Camera Photography
MagSafe-style magnetic mount
80g aluminum body
Fits 30-60mm eyepieces
Pros
- Magnetic attachment for ultra-quick swaps
- Lightweight at only 80g
- Precision-machined aluminum
Cons
- Adhesive ring can slip in heat
- Light bleed on small camera phones
- Less stable with very heavy phones
The FANAUE magnetic adapter is the most fun I have had with a smartphone telescope adapter. I slap my iPhone onto the magnetic ring, it snaps into place, and I am shooting within seconds. The 80g weight is the lightest on this list, which makes it the only adapter I forget I am carrying. For backyard sessions and quick daylight-to-night transitions, the FANAUE is unbeatable for convenience.
Build quality is better than I expected. The aluminum body is precision-machined, and the rotating adjustment mechanism gives me a surprising amount of fine control once the magnetic ring is attached. The 30-60mm eyepiece range is the widest among budget options, and it covered all of my astronomy eyepieces plus the larger eyepiece on my spotting scope.
For afocal imaging, the FANAUE works well as long as your phone has a centered or offset-but-large camera. On my iPhone 14 Pro Max, the magnetic ring sits perfectly over the camera lens. On a thinner Pixel, there was minor light bleed because the camera sits at a different height. The fix is a small foam baffle around the lens, which is a 30-second mod.
The main concern is heat. On a 90 degree day, the adhesive ring that holds the metal plate to the phone can lose grip if you press the phone in repeatedly. I have not had the magnet slip in normal use, but I do keep a spare adhesive ring in my kit. The other compromise is that very heavy phones (with a large case and accessories) can cause the magnet to rotate slightly out of alignment, so I check the framing every few shots.
Who should buy the FANAUE
Buy the FANAUE if you want a fast, fun, lightweight adapter and your phone supports magnetic mounting. It is the best pick for casual astrophotography, quick digiscoping sessions, and anyone who hates fumbling with clamps in the dark. The aluminum body and 2-year warranty also make it a long-term value.
Who should skip the FANAUE
Skip the FANAUE if you use an Android phone without MagSafe-style magnets, or if you shoot in extreme heat where adhesives can fail. Also skip it if you need absolute rigidity for long planetary videos, because magnetic mounts cannot match the firmness of a clamped 3-axis adapter. For those cases, the Move Shoot Move Tridaptor remains the better tool.
8. Celestron Smartphone Adapter and Bluetooth Remote Kit – Best Budget Bluetooth Bundle
Celestron Smartphone Adapter & Bluetooth Remote for Telescope Eyepieces
Includes Bluetooth remote
Fits 29-45mm eyepieces
Compact travel design
Pros
- Comes with Bluetooth remote
- Budget-friendly Celestron quality
- 2-year warranty
Cons
- Single-clamp design limits fine X-Y tuning
- Can press phone side buttons
- Setup is slower than 3-axis
The Celestron Basic with Bluetooth remote is the kit I give to friends who are just starting out. You get the proven Celestron Basic adapter plus a small Bluetooth shutter remote for less than the price of a Move Shoot Move Tridaptor alone. For beginners, the remote is a game-changer because it removes the wobble of tapping the on-screen shutter button.
For afocal imaging, the kit performs the same as the regular Celestron Basic. The 29-45mm eyepiece range covers all 1.25 inch eyepieces, and the metal frame is the same durable construction. The Bluetooth remote pairs instantly with both iPhone and Android, and I have never had a connection drop mid-session.
Why is this adapter last on the list? The single-knob X-Y alignment. Many users, including me on the first try, find that the single tightening knob cannot independently adjust left-right and up-down. To compensate, you loosen the whole clamp, slide the assembly, and re-tighten, which is the same workflow as the Basic. The Bluetooth remote does not fix that.
The other issue is the clamp pressing phone buttons. On my iPhone 14 Pro, the clamp briefly hit the side button during one session, which woke the screen. A small piece of tape or repositioning solved it, but it is a flaw worth knowing. The 3.8 average rating reflects these friction points, and I would still buy this kit for a beginner who values the included remote.
Who should buy the Celestron Bluetooth Kit
Buy this kit if you want an affordable Celestron adapter and a Bluetooth remote in one box. It is the right pick for first-time users, casual astrophotographers, and anyone who already plans to buy a remote separately. Pairing it with a beginner-friendly telescope makes for a complete starter package.
Who should skip the Celestron Bluetooth Kit
Skip this kit if you already own a Bluetooth remote, or if you want the best alignment system for the money. The Move Shoot Move Tridaptor is a more refined experience for serious digiscoping. Also skip it if your phone has a large side button layout, because the clamp can press buttons more easily than other models.
How to Choose the Best Telescope Adapter for Your Smartphone?
Picking the right smartphone telescope adapter comes down to matching the mount to your optics, your phone, and your patience for setup. Below are the six factors I consider every time I buy or recommend an adapter. If you weigh these against the eight picks above, you will end up with the right tool for the way you actually shoot.
Eyepiece Diameter and Compatibility
The first spec to check is the outer diameter of your eyepieces. Most 1.25 inch astronomy eyepieces measure 30-35mm at the barrel, while 2 inch eyepieces measure 46-50mm. Adapters like the GOSKY cover 28-47mm, which fits nearly every 1.25 inch eyepiece but may struggle with oversize 2 inch models. Premium adapters like the Move Shoot Move Tridaptor cover 22-61mm, which handles both standards plus most spotting scope and binocular eyepieces.
Always measure your largest eyepiece’s outer diameter before ordering, especially if you have a wide-field or zoom eyepiece. A millimeter of clearance is enough to seat the adapter, but you want a few millimeters of margin for easy on-off in the field. If you own multiple telescopes with different eyepiece standards, the safest buy is an adapter with the widest range you can afford.
Number of Adjustment Axes
Two-axis adapters (X and Y) let you center the camera over the eyepiece in two directions. Three-axis adapters add a Z (forward-back) or eye relief control, which is critical for eyepieces with different exit pupil positions. For moon photography and casual planet shots, 2-axis is enough. For high-magnification planetary work or eyepiece projection, 3-axis makes a real difference in image quality.
If you already use a Bahtinov mask or a star test, you appreciate fine control. If you mostly shoot the moon, the 2-axis NexGO or even the single-knob Basic is plenty. Match the number of axes to how picky you are about the final image, not to the price tier alone.
Build Quality and Materials
Metal bodies resist flex, cold, and time better than plastic. The Move Shoot Move Tridaptor is fully metal, the Celestron NexYZ is metal and fiber-reinforced plastic, and the GOSKY uses zinc alloy for a strong budget build. Pure plastic adapters are fine for occasional use but tend to develop play in the clamps after a season.
If you shoot in cold weather, weight is also a factor. Heavier adapters add stability but can throw off balance on small refractors. I keep a small Velcro counterweight in my kit for any adapter over 200g on a light mount. The FANAUE’s 80g aluminum body is the lightest serious option I have tested.
Phone Clamp and Fit
Clamp width is the most overlooked spec. Most adapters fit phones 2.13-3.54 inches wide, which covers everything from an iPhone Mini to an iPhone Pro Max with a thin case. Thick cases (OtterBox, battery cases) can push you past the limit, so I remove my case before attaching any adapter. Spring-loaded clamps are faster than screw clamps, and metal jaws grip better than plastic.
Look for clamps that do not press side buttons. A clamp that hits the power button will wake your phone mid-exposure, ruining long planetary shots. The NexYZ, NexGO, and Tridaptor all have well-designed clamps, while the Basic Bluetooth Kit and a few budget models occasionally need a small shim.
Bluetooth Remote and Shake Control
For long exposures and high-magnification planet shots, any touch to the phone causes shake. A Bluetooth remote, like the one included with the Tridaptor or the Celestron Bluetooth Kit, lets you trigger the shutter without touching the phone. Some apps also support voice control, which is a free alternative if you do not want a remote.
If you already use a 3-second timer in your phone’s camera app, that gives you most of the same benefit. The Bluetooth remote is faster and easier in the dark, but it is not strictly required. Decide based on how often you shoot in low light at high magnification.
Price and Use Case
Under thirty dollars gets you a workable adapter, but you trade off fine alignment and durability. The thirty-to-sixty dollar range is the sweet spot, with options like the NexGO, Tridaptor, and FANAUE that balance price and precision. Above sixty dollars, the NexYZ offers the best 3-axis experience in the Celestron line.
My rule of thumb is to spend what your telescope is worth. A fifty-dollar adapter on a two-thousand-dollar telescope is a small investment for the images you can capture. A premium adapter on a basic 70mm refractor is overkill unless you specifically want the build quality. The eight options above cover every reasonable budget and use case, so pick the one that fits how you actually shoot.
Frequently Asked Questions
What is the best telescope for using with a mobile phone?
The best telescope for mobile phone imaging is one with a stable mount, smooth focuser, and standard 1.25 inch eyepieces. Popular choices include 8 inch Dobsonians for deep-sky, 80-100mm refractors for portability, and computerized scopes like the Celestron NexStar 6SE or 8SE for tracking. Pair the telescope with a 3-axis smartphone adapter like the Celestron NexYZ for the best results.
How do I connect my phone to my telescope?
To connect a phone to a telescope, attach a smartphone adapter to the eyepiece, place your phone in the clamp, center the camera lens over the eyepiece using the adapter’s adjustment knobs, and tighten the clamp. Focus the telescope first, then use a Bluetooth remote or 3-second timer to capture shake-free images. The Celestron NexYZ and Move Shoot Move Tridaptor are two of the easiest adapters to use for first-time setups.
Which telescope camera can connect to my phone?
A dedicated telescope camera like the Celestron NexImage or ZWO ASI can connect to your phone through a USB adapter, but most beginners use a smartphone telescope adapter to shoot through the eyepiece instead. Smartphone adapters are cheaper, easier to use, and produce excellent results on the moon, planets, and bright deep-sky objects. For longer exposures, a dedicated astronomy camera is better.
What is the best phone adapter for a monocular?
The best phone adapter for a monocular is one that fits small eyepiece diameters (under 30mm) and holds the phone firmly. The GOSKY Spotting Scope Phone Adapter and Celestron Basic both handle monoculars well at 28-47mm and 29-45mm respectively. For premium monoculars with wider eyepieces, the Move Shoot Move Tridaptor covers 22-61mm and provides 3-axis fine control.
Final Verdict
After testing all eight adapters over the past three months, the Celestron NexYZ remains my top pick for the best telescope adapters for smartphones, thanks to its patented 3-axis alignment, durable build, and quick phone swaps. For budget buyers, the GOSKY delivers surprising metal quality at the lowest price, while the Move Shoot Move Tridaptor is the best premium pick for serious digiscoping and planetary work. If you want the lightest, fastest setup, the FANAUE magnetic adapter is hard to beat for casual sessions.
No matter which of these best telescope adapters for smartphones you choose in 2026, start with the moon, use a Bluetooth remote or 3-second timer, and give yourself ten minutes to align before judging the result. With the right adapter, your phone is a capable astronomy camera, and the views you can capture at the eyepiece are worth the small investment.
