Smart telescopes have changed the game: no need to know your way around the sky or to align a mount. You set the device down, pick a target on your smartphone, and the astrophotography happens on its own. But between ZWO, Vaonis, Unistellar, DwarfLab and Celestron, which one should you choose in 2026? Here is our complete buying guide.
What is a smart telescope?
A smart telescope combines optics, a camera, a motorized GoTo mount and processing software, all controlled from an app. It automatically locates deep-sky objects, tracks them, stacks hundreds of frames and delivers a colour image in minutes — even from a city balcony. It is the ideal way to start astrophotography without the usual learning curve.
How to choose: the 4 criteria that matter
1. Aperture (the optics diameter) sets how much light is captured: from 30 mm (ultra-portable) to 152 mm (Celestron Origin). Bigger catches fainter objects, but is heavier and pricier.
2. The sensor defines final resolution: from 2 MP (ZWO Seestar) to 12.5 MP (Vaonis Vespera Pro 2). More megapixels means sharper, larger images.
3. Portability: from 1.3 kg (DwarfLab Dwarf 3) to nearly 9 kg. For travel or a light tripod, weight is decisive.
4. Budget: from €249 (Vaonis Hestia) to €4,199 (Unistellar eVscope 2).

Our 2026 picks by category
🥇 Best value to start: ZWO Seestar S50
At €549, the Seestar S50 (50 mm, Sony IMX462 sensor) is the ideal entry point: compact (3 kg), simple, versatile (deep sky, Moon, Sun). Its 2 MP resolution is modest, but to discover astrophotography the fun-to-price ratio is unbeatable. For lighter and cheaper, the Seestar S30 (€349) does the job.
📷 Best image quality: Vaonis Vespera Pro 2 & Vespera III
Vaonis aims for photographic excellence. The Vespera III (€2,490, 8.5 MP) and Vespera Pro 2 (€2,990, 12.5 MP — the highest resolution on the market) offer apochromatic optics and a mosaic mode for very wide fields. For frame-worthy images, this is the reference.
🎒 Most portable: DwarfLab Dwarf 3
At €549 and just 1.3 kg, the Dwarf 3 (8.3 MP Sony IMX678) bets on lightness and a dual lens (tele + wide). Perfect for travel astrophotography and daytime nature.
🔬 For science and urban skies: Unistellar
Unistellar (Odyssey €2,299, eQuinox 2 €2,499, eVscope 2 €4,199) shine in the city thanks to their image processing, and let you join real citizen science campaigns. A unique experience beyond simple photography.
🏆 Absolute high end: Celestron Origin
With its 6″ RASA optics (152 mm, f/2.2), the Celestron Origin (€3,999) is the brightest of all: it captures in record time what others need an hour to do. For demanding enthusiasts only.
