With dozens of smart telescopes available in 2026, choosing the right model comes down to your budget, desired portability, and favorite deep-sky objects. All recommendations in this guide are based on hands-on testing directly from my light-polluted rooftop and balcony in Utrecht, the Netherlands (Bortle 7). Use the navigation below to jump to my specific hand-on reviews, budget tiers or explore my interactive comparison tools and real photos.

Key Technical Factors to Consider Before Buying

Aperture & Optical Resolving Power
Aperture (the diameter of the primary lens or mirror) determines total light-gathering capacity and physical resolving power. Larger apertures collect a larger volume of light photons and resolve significantly finer details on compact deep-sky objects compared to smaller budget optics.
Focal Ratio & Exposure Speed (f/-number)
How fast an image forms on your camera sensor depends on the focal ratio (focal length divided by aperture), not aperture alone. Fast optical systems (e.g., f/2.2 to f/4) expose celestial objects much faster, requiring shorter exposure times to reach a high signal-to-noise ratio compared to slower systems (f/5 to f/7 or higher).
Digital Resolution & Image Scale
Megapixels alone do not dictate sharpness. What matters is image scale (arcseconds per pixel), determined by combining your focal length and pixel size. An optimal image scale (typically 1–2″/px) balances fine detail without making stars look blocky (under-sampled) or bloated and dim (over-sampled).
Optical Design & Maintenance
Smart telescopes generally use Refractors (triplet, quadruplet, or sextuplet APO ED glass) or Reflectors (Newtonian, Rowe-Ackermann Schmidt Astrographs, or Maksutov-Cassegrains). Refractors are completely maintenance-free with zero alignment required, whereas mirror-based reflectors may occasionally require manual or factory collimation.
Field of View (FoV) & Objects
Expressed in angular degrees (°), FoV determines how much sky your camera sensor covers. Wide fields of view (2°–3°) are ideal for sprawling objects like the Andromeda Galaxy or Orion Nebula, while narrower fields (under 1°) suit smaller objects like the Whirlpool Galaxy. Note: Most smart telescopes lack the aperture and focal length for high-resolution planetary imaging (Jupiter, Saturn, Mars). For dedicated setups, check out my Planetary Telescope Guide.
Mosaic & Framing Modes
Most recent smart telescope models feature automated stitching (such as Seestar’s framing mode or Vaonis CovalENS) that combines multiple panels to capture up to 2x linearly or 4x total sky surface area.
Filters for Urban Light Pollution
Duo-Band / Light Pollution filters (targeting OIII and H-alpha lines) are essential for capturing clean emission nebulae from suburban or urban skies. Additionally, broadband Astro filters (found on the DWARF 3 and DWARF Mini) pass light into the near-infrared spectrum (430–690nm+), suppressing atmospheric turbulence (seeing) and sharpening views of galaxies and star clusters.
Equatorial (EQ) Tracking Mode
Standard Alt-Az mounts track in step-like movements that cause field rotation over time. Smart telescopes equipped with an EQ tracking mode align with Earth’s rotational axis, eliminating field rotation and enabling longer exposures (30s to 120s) for significantly cleaner, deeper exposures.
App Ecosystem, Connectivity, Battery & Storage
Look for versatile software features such as daytime scenery tracking, solar system auto-centering, in-app stacking, and Station Mode (connecting to your home Wi-Fi), and planning modes which allow full automation. Battery runtimes range from 4 to 11 hours, while internal storage capacities range from 25GB up to 225GB for saving photos and videos in various formats.
Real-World Images
Real-world images best showcase performance. Below are actual test captures I stacked and processed from my urban rooftop in Utrecht, The Netherlands (Bortle 7, 52° North). Total integration times range from 45 to 90 minutes (solar/lunar images are stacked TIFFs or RAW AVI video frames).

Hello greetings, I wanted to ask if the Seestar will have a pro version? with more aperture and longer focal length, greetings from Chile
Let’s wait and see. ZWO usually announces new product updates at AP conferences like NEAF, next one is in April 2024.
I was wondering if any of these can work while plugged into a battery pack. That would extend the battery life but I don’t know if that would interfere with any of the functionality.
Hi Scott, I tested the Seestar S50 and the Vespera classic/II, and they both work fine when an extra battery pack is plugged in.
They re-charge while imaging, no problem.
Background: I own the Meade LX90 12″ ACF, Televue 102 Refractor, Orion 150mm Maksutov and Lunt LS152THa solar conventional telescopes. In 2020 I purchased a Vaonis Stellina to use in public outreach during Covid. Last year I ordered the Seestar S50 and then a month later the Vaonis Vespera Pro upon its release. I sold the Seestar when it arrived, unopened. I’m awaiting delivery of my Vespera Pro.
Nice review with an excellent comparison of features. However, you left out one critical parameter: sensitivity. I was happy with Stellina when I received it in June of 2020, however, it compares poorly with today’s offerings. Stellina is good to Mag 13, eVScopes can image to Mag 18 and Vespera Pro is claimed to be Mag 16. I have a friend that has imaged the Hershel 400 with his eVScope II. That would not be remotely possible with Stellina because of the wider field and 5 mag lower sensitivity. I have a friend with an original Vespera and his images of M51, Whirlpool Galaxy, are superior to Stellina’s despite its 1/3 pixel resolution and 50mm vs 80mm aperture optics. Vespera supposedly also has a sensitivity of mag 13 but it seems to do better than that. I suspect that its Sony IMX462 camera sensor has better sensitivity than Stellina’s Sony IMX178 chip which is now a 11+ year old design. And the precision apochromatic quadraplex lens optics may also help Vespera. It appears that Vaonis has stopped selling Stellina although I have not yet seen a formal announcement, it’s always “out of stock”… it’s just technically obsolete. I’m looking forward to seeing how the new Vespera Pro performs.
[ I’m surprised that Celestron’s new Origin Telescope uses an IMX178LQJ, Although it is a more advanced unit with better features, it still has the same 6.3 mega pixel resolution of the earlier IMX178 family sensors used in Stellina. Without Stellina’s mechanical field decorator, Origin will necessarily produce more misaligned pixels in the software rotation matrix transform, necessarily yielding a softer image.]
So, adding sensitivity to your review would be extremely useful.
It would be useful to know which scopes here can connect to an existing wifi network. If the scope can only use it’s own wifi network then range can be a problem if you want to go indoors, as well as it means your phone will no longer have internet access while connected to the scope (unless you can use the phones cellular connection). The Unistellar eVscope eQuinox 2 seems to have a particularly limited wifi range.
Seestar, Dwarflab an Celestron APPs have a station/STA/network mode that connects your smart telescope to your home WiFi network. Vaonis and Unistellar only have a direct WiFi connection and do not (yet) support a network mode. Beware that APPs are updated frequently (especially Seestar and Dwarflab seem to be very active) so this and other functionalities may change in the future.
Celestron Origin Intelligent Home Observatory camera which you say is a little outdated and can be removed do you think it can upgraded in the future
Thanks for the comprehensive comparison! I am new to astrophotography and will be considering the S30 or Dwarf Mini; I have read the Dwarf Mini allows for an exposure time up to 120 seconds, and also has low rejection rate in comparison to the Seestar. In addition it also has Stellar Studio support. They otherwise look pretty comparable in specs – would you recommend the Mini over the S30 because of these features?
Both are great budget-friendly options for getting started in astrophotography, and there isn’t a huge difference between them. You can use my comparison tool and the smart telescope guide on my website to explore the distinctions and make an informed choice.
