What Is a Smart Telescope? Unistellar & Vaonis Explained
A smart telescope is a fully automated, computerized telescope with a built-in camera instead of an eyepiece — you control it from your phone, and it finds, tracks, and photographs the night sky for you. Unistellar and Vaonis are the two best-known brands, offering compact "point-and-shoot" instruments that reveal colorful galaxies and nebulae in minutes, even from a light-polluted backyard.
If you have ever struggled to aim a traditional telescope or been disappointed that faint galaxies look like dim gray smudges through the eyepiece, a smart telescope solves both problems at once. Here's how these devices work, what makes Unistellar and Vaonis different, what they cost, and whether one belongs on your wish list.
What is a smart telescope?
A smart telescope (sometimes called a "smart scope" or "app-controlled telescope") is an all-in-one device that combines the optics, a motorized mount, a digital camera sensor, and onboard software into a single sealed unit. There's no manual star-hopping, no fussing with a finderscope, and often no eyepiece at all. You set it on its tripod, open the companion app on your phone or tablet, tap a target, and watch the image appear on your screen.
The key difference from a normal telescope is how you observe. Instead of putting your eye to an eyepiece, you look at a live, continuously improving image on your device. The telescope captures many short exposures and stacks them together in real time, so a faint galaxy that would be nearly invisible to your eye slowly brightens into a detailed, colorful picture. Several people can view the same image on their own phones at once, which makes smart telescopes great for families and outreach.
How does a smart telescope work?
Under the hood, a smart telescope automates the same steps an experienced astronomer would do by hand:
- Automatic alignment. When you power it on, the telescope photographs the sky and compares the star patterns to an internal database (a technique called plate-solving) to figure out exactly where it's pointing.
- GoTo pointing. You choose a target in the app and motors swing the telescope to it automatically. This is the same idea behind a computerized GoTo telescope, just built into a sealed, camera-based body.
- Tracking. The mount slowly turns to counteract Earth's rotation, keeping the target centered so it doesn't drift out of frame.
- Live stacking. The camera takes a stream of short exposures and the software adds them together, canceling out noise and building up faint detail. Over a few minutes, the on-screen image gets brighter, sharper, and more colorful.
- Light-pollution processing. Built-in software (and optional filters) reduces the orange glow of city skies, so smart telescopes perform far better in suburban and urban backyards than a traditional scope of the same size.
Because the whole workflow is automated, smart telescopes are essentially entry-level astrophotography machines that anyone can operate on the first night — no collimation, no polar alignment, and no experience required.
Unistellar smart telescopes explained
Unistellar is a French company that helped kick off the smart-telescope category. Its instruments use a reflector-style optical design paired with a sensitive camera and the company's "Enhanced Vision" live-stacking technology, plus smart light-pollution reduction for city skies. The current family includes the eQuinox 2 (app-only viewing), the eVscope 2 (which adds a Nikon-designed electronic eyepiece so you can still look "through" the scope), and the newer Odyssey and Odyssey Pro models. Prices generally run from around $2,000 up to roughly $4,500 for the flagship editions.
One thing that sets Unistellar apart is citizen science: owners can join organized campaigns to observe asteroid occultations, comets, exoplanet transits, and near-Earth objects, contributing real data to research networks. You can browse the current lineup and accessories in our Unistellar smart telescopes collection.
Vaonis smart telescopes explained
Vaonis, also based in France, is known for elegantly designed smart telescopes and a polished app experience. Its Vespera line (including the compact Vespera and the higher-resolution Vespera Pro) focuses on portable, refractor-based deep-sky imaging, with a "mosaic" mode that stitches frames together for a wider field of view. Vaonis also makes the Hestia, a clever, budget-friendly device that turns your smartphone itself into a smart telescope using your phone's camera — a great low-cost way to try the concept.
Vaonis pricing spans a wide range: the smartphone-based Hestia starts at a few hundred dollars, while the Vespera models sit in the roughly $1,500–$3,000 range depending on the version and bundle. Explore the full range in our Vaonis smart telescopes collection.
Smart telescope vs. a traditional beginner telescope
A smart telescope is not automatically "better" than a classic telescope — it's a different experience aimed at a different goal. Here's how the two compare:
| Feature | Smart telescope (Unistellar / Vaonis) | Traditional beginner telescope |
|---|---|---|
| How you view | Live image on your phone or tablet | Directly through an eyepiece with your eye |
| Finding objects | Fully automatic (tap a target in the app) | Manual aiming or optional GoTo mount |
| Best for | Deep-sky galaxies & nebulae, easy astrophotography | Moon, planets, and hands-on visual observing |
| City / light pollution | Excellent (software + filters cancel glow) | Limited without dark skies |
| Setup & learning curve | Minimal — ready in minutes | Some practice needed |
| Typical price | ~$250 to $4,500 | ~$150 to $500 for a solid starter |
| Runs on | Battery + app (software-dependent) | No power or software needed |
Who should buy a smart telescope — and who shouldn't?
A smart telescope is a great fit if you:
- Live under bright suburban or city skies and want to see galaxies and nebulae anyway.
- Want photos to share, without learning the deep end of astrophotography.
- Value convenience — a device that's ready in minutes and controlled from your couch or patio.
- Plan to share the view with family, kids, or a group on multiple phones at once.
You may be happier with a traditional telescope if you:
- Love the timeless experience of looking through an eyepiece with your own eye.
- Mostly want to observe the Moon and planets, where classic scopes shine.
- Prefer to learn the sky by hand and keep costs down.
If a $2,000-plus smart telescope is more than you want to spend right now, you don't have to miss out. A capable, in-stock starter like the Explore Scientific FirstLight 114mm Reflector with EQ3 mount or the grab-and-go FirstLight 100mm Maksutov kit will show you the Moon, planets, and brighter deep-sky objects for a fraction of the price.

Frequently asked questions
Do you look through a smart telescope like a normal one?
Usually no. Most smart telescopes replace the eyepiece with a camera, so you view a live, stacked image on your phone or tablet. A few models — such as the Unistellar eVscope 2 and Odyssey Pro — add an electronic eyepiece so you can still peer "through" the scope, but the picture you see is still digital.
Are smart telescopes good for beginners?
Yes. They're arguably the easiest telescopes to use because everything — finding, tracking, and imaging — is automated. The main barrier is price, not difficulty. If your budget is tight, a simple manual or GoTo beginner telescope is a friendlier first step.
Can a smart telescope show planets and the Moon?
Smart telescopes are optimized for deep-sky objects like galaxies and nebulae, where their live-stacking really shines. They can capture the Moon and brighter planets, but for crisp, high-magnification planetary and lunar detail, a traditional telescope with a good eyepiece often does better.
How much does a smart telescope cost?
It varies widely. Smartphone-based options like the Vaonis Hestia start around a few hundred dollars, while flagship Unistellar and Vaonis models range from roughly $2,000 to $4,500 depending on the model, sensor, and bundle.
Do smart telescopes work in the city?
Yes — this is one of their biggest strengths. Onboard software and optional light-pollution filters cancel much of the orange city glow, so you can image deep-sky objects from a backyard where a traditional telescope of the same size would show very little.
