Brand showdown # Seestar vs Vespera vs Unistellar: Which Smart Telescope Brand Fits You? Updated November 12, 2026 By [Smart Telescope Review Editorial Team](https://smarttelescopereview.com/about/) [How we research](https://smarttelescopereview.com/how-we-research/) Prices are approximate and change often, so check the current price before you buy. ## Key takeaways - **ZWO Seestar** wins on value: built-in dual-band filters, a solar filter in the box, EQ mode and mosaics, from about $664 (S30 Pro) to $999 (S50 Pro). - **Vaonis Vespera** sells build and battery: 11 h (Vaonis) and a five-year warranty on the Vespera 3 and Pro 2, but no EQ mode and filters cost extra. - **Unistellar** sells aperture and simplicity: 85–114 mm Newtonians, a Nikon eyepiece on the Odyssey Pro and eVscope 2, and NASA/SETI citizen science. - Unistellar's narrow 45 × 34 arcminute field and lack of mosaic mode make it a small-galaxy instrument; big nebulae and Andromeda don't fit. - Most buyers should start with the Seestar S50 Pro; pay more only for a specific reason: warranty and battery (Vespera) or aperture and an eyepiece (Unistellar). ## Our top picks - 1![ZWO Seestar S50 Pro Smart Telescope](https://smarttelescopereview.com/_astro/seestar-s50-pro.BOj1gADQ_1F3c68.webp)Best value overall: 50 mm, built-in dual-band filter, EQ mode and a 9 h battery (ZWO), about $999[ZWO Seestar S50 Pro Smart Telescope](https://smarttelescopereview.com/smart-telescopes/seestar-s50-pro/)50 mm f/5.2 · 2.45° × 1.38° · 6.2 lb8.6**$$**$$Mid-rangePrice tier: Mid-range[Check price on Amazon](https://www.amazon.com/dp/B0HP1RDLVP?tag=smarttelescopereview.com-20) - 2![ZWO Seestar S30 Pro Smart Telescope](https://smarttelescopereview.com/_astro/seestar-s30-pro.DqtA63or_29e8vC.webp)Widest field and lightest kit: about 4° × 2.2° at 1.65 kg, about $664[ZWO Seestar S30 Pro Smart Telescope](https://smarttelescopereview.com/smart-telescopes/seestar-s30-pro/)30 mm f/5.3 · 3.99° × 2.24° · 3.6 lb8.5**$$**$$Mid-rangePrice tier: Mid-range[Check price](https://www.amazon.com/dp/B0GYX9GSVX?tag=smarttelescopereview.com-20) - 3![Vaonis Vespera 3 Smart Telescope](https://smarttelescopereview.com/_astro/vaonis-vespera-3.Dv9oBlii_13l09G.webp)Best premium build: 11 h battery, multi-night projects, five-year warranty, about $2,490[Vaonis Vespera 3 Smart Telescope](https://smarttelescopereview.com/smart-telescopes/vaonis-vespera-3/)50 mm f/4.9 · 2.6° × 1.4° · 11 lb8.1**$$$**$PremiumPrice tier: Premium[Check price](https://www.amazon.com/dp/B0GY1PT485?tag=smarttelescopereview.com-20) - 4![Vaonis Vespera Pro 2 Smart Telescope](https://smarttelescopereview.com/_astro/vaonis-vespera-pro-2.DT17Tmq0_1TIPwW.webp)Finest 50 mm sampling: 12.5 MP square sensor and automatic darks, about $2,990[Vaonis Vespera Pro 2 Smart Telescope](https://smarttelescopereview.com/smart-telescopes/vaonis-vespera-pro-2/)50 mm f/4.9 · 1.6° × 1.6° · 11 lb8.1**$$$**$PremiumPrice tier: Premium[Check price](https://www.amazon.com/dp/B0GY1TH8QQ?tag=smarttelescopereview.com-20) - 5![Unistellar eQuinox 2 Smart Telescope](https://smarttelescopereview.com/_astro/unistellar-equinox-2.DFXKeXNc_1SBFiz.webp)Most aperture for the money: 114 mm and an 11 h battery (Unistellar), about $2,319[Unistellar eQuinox 2 Smart Telescope](https://smarttelescopereview.com/smart-telescopes/unistellar-equinox-2/)114 mm f/4 · 0.76° × 0.57° · 15.4 lb7.4**$$$**$PremiumPrice tier: Premium[Check price](https://www.amazon.com/dp/B0BRNSWXLS?tag=smarttelescopereview.com-20) - 6![Unistellar Odyssey Smart Telescope](https://smarttelescopereview.com/_astro/unistellar-odyssey.CFZCe6q1_oGFRe.webp)Easiest Unistellar: 85 mm with autofocus and no collimation, about $2,079[Unistellar Odyssey Smart Telescope](https://smarttelescopereview.com/smart-telescopes/unistellar-odyssey/)85 mm f/3.9 · 0.75° × 0.56° · 8.8 lb7.6**$$$**$PremiumPrice tier: Premium[Check price](https://www.amazon.com/dp/B0CQMD3R3Z?tag=smarttelescopereview.com-20) - 7![Unistellar Odyssey Pro Smart Telescope](https://smarttelescopereview.com/_astro/unistellar-odyssey-pro.C5e5XTJR_1Qz7im.webp)Best for outreach: Nikon electronic eyepiece on the Odyssey optics, about $3,679[Unistellar Odyssey Pro Smart Telescope](https://smarttelescopereview.com/smart-telescopes/unistellar-odyssey-pro/)85 mm f/3.9 · 0.75° × 0.56° · 8.8 lb7.5**$$$$**FlagshipPrice tier: Flagship[Check price](https://www.amazon.com/dp/B0CQMLNR95?tag=smarttelescopereview.com-20) ### On this page 9 sections - [The three philosophies in one paragraph each](#the-three-philosophies-in-one-paragraph-each) - [Spec comparison: all nine models](#spec-comparison-all-nine-models) - [Field of view: the difference you’ll notice first](#field-of-view-the-difference-youll-notice-first) - [Light pollution and filters](#light-pollution-and-filters) - [Mount and EQ mode](#mount-and-eq-mode) - [Build, battery, warranty and software](#build-battery-warranty-and-software) - [Which brand should you buy?](#which-brand-should-you-buy) - [How we chose](#how-we-chose) - [FAQ](#faq) ## Before you choose - [The 7 Best Smart Telescopes of 2026: Ranked for Backyard, Travel and Budget](https://smarttelescopereview.com/posts/best-smart-telescopes-2026/) - [Celestron Origin Mark II vs Seestar S50 Pro: Is the $4,299 Smart Scope Worth 4×?](https://smarttelescopereview.com/posts/celestron-origin-vs-seestar/) - [Seestar S30 Pro vs S50 Pro: Which ZWO Smart Telescope Should You Buy?](https://smarttelescopereview.com/posts/seestar-s30-pro-vs-s50-pro/) ZWO, Vaonis and Unistellar build smart telescopes that look alike on a spec sheet: a motorized tube, a camera, a phone app and live stacking. They’re built on three different ideas, though. ZWO’s Seestar line packs the most features into the lowest price. Vaonis’ Vespera line sells premium build, long battery life and a long warranty. Unistellar sells aperture, autofocus and, on two models, a real eyepiece you can look into. This comparison covers the nine current models from those three brands that were on Amazon on November 12, 2026. We haven’t tested these telescopes ourselves: it’s built from maker spec pages and named independent reviews, and where a test result appears we say who ran it. Prices are Amazon prices on that date, so check today’s price before you buy. ## The three philosophies in one paragraph each ZWO Seestar: value and features. Every current Seestar has a built-in duo-band (H-alpha/OIII) filter, a solar filter in the box and an EQ mode with ZWO’s optional TH10 head. The [Seestar S50 Pro](https://smarttelescopereview.com/smart-telescopes/seestar-s50-pro/) is the 50 mm flagship at about $999; the [S30 Pro](https://smarttelescopereview.com/smart-telescopes/seestar-s30-pro/) is the 30 mm travel model at about $664. The catch is small aperture and full reliance on the phone app. Vaonis Vespera: build, battery and warranty. The [Vespera 3](https://smarttelescopereview.com/smart-telescopes/vaonis-vespera-3/) and [Vespera Pro 2](https://smarttelescopereview.com/smart-telescopes/vaonis-vespera-pro-2/), launched April 11, 2026, use a new flat-field apochromatic quadruplet, an 11-hour battery (Vaonis) and a five-year warranty. The Singularity app is polished. There’s no EQ mode on any Vespera, and light-pollution, dual-band and solar filters are all sold separately. Unistellar: aperture and the eyepiece. Unistellar uses 85 mm and 114 mm Newtonian reflectors, much bigger than anything ZWO or Vaonis sells. The [Odyssey](https://smarttelescopereview.com/smart-telescopes/unistellar-odyssey/) has autofocus and needs no collimation, and the [Odyssey Pro](https://smarttelescopereview.com/smart-telescopes/unistellar-odyssey-pro/) and [eVscope 2](https://smarttelescopereview.com/smart-telescopes/unistellar-evscope-2/) add a Nikon electronic eyepiece. Light pollution is handled in software (“Deep Dark Technology”) rather than with a filter, the field is narrow, and there’s no mosaic mode. The free app runs NASA/SETI citizen-science campaigns. ## Spec comparison: all nine models | Model | Aperture / focal length | Native field | Sensor output | Dual-band filter | EQ mode | Battery (maker) | Weight | Warranty | Price (Nov 12) | | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | | [Seestar S50 Pro](https://smarttelescopereview.com/smart-telescopes/seestar-s50-pro/) | 50 / 260 mm, f/5.2 | 2.45° × 1.38° | 8.3 MP | Built in | Yes (TH10) | 9 h | 2.8 kg | 2 yr | ~$999 | | [Seestar S30 Pro](https://smarttelescopereview.com/smart-telescopes/seestar-s30-pro/) | 30 / 160 mm, f/5.3 | 3.99° × 2.24° | 8.3 MP | Built in | Yes (TH10 + TC20) | 6 h | 1.65 kg | 2 yr | ~$664 | | [Vespera 3](https://smarttelescopereview.com/smart-telescopes/vaonis-vespera-3/) | 50 / 245 mm, f/4.9 | 2.6° × 1.4° | 8.3 MP | Optional | No | 11 h | 5 kg | 5 yr | ~$2,490 | | [Vespera Pro 2](https://smarttelescopereview.com/smart-telescopes/vaonis-vespera-pro-2/) | 50 / 245 mm, f/4.9 | 1.6° × 1.6° | 12.5 MP | Optional | No | 11 h | 5 kg | 5 yr | ~$2,990 | | [Vespera II](https://smarttelescopereview.com/smart-telescopes/vaonis-vespera-ii/) | 50 / 250 mm, f/5 | 2.5° × 1.4° | 8.3 MP | Optional | No | 4 h | 5 kg | 3 yr | ~$1,590 | | [Odyssey](https://smarttelescopereview.com/smart-telescopes/unistellar-odyssey/) | 85 / 320 mm, f/3.9 | 45′ × 34′ | ~3.4–4.1 MP | None (software) | No | 5 h | 4 kg | 2 yr | ~$2,079 | | [Odyssey Pro](https://smarttelescopereview.com/smart-telescopes/unistellar-odyssey-pro/) | 85 / 320 mm, f/3.9 | 45′ × 34′ | ~4.1 MP | None (software) | No | 5 h | 4 kg | 2 yr | ~$3,679 | | [eQuinox 2](https://smarttelescopereview.com/smart-telescopes/unistellar-equinox-2/) | 114 / 450 mm, f/4 | 46′ × 34′ | 6.2 MP | None (software) | No | 11 h | 7 kg | 2 yr | ~$2,319 | | [eVscope 2](https://smarttelescopereview.com/smart-telescopes/unistellar-evscope-2/) | 114 / 450 mm, f/4 | 46′ × 34′ | 7.7 MP | None (software) | No | 9 h | 7 kg | 2 yr | ~$3,999 | Weights are the maker’s figure for the telescope; tripods add more. Battery figures are maker claims, and reviewers usually get less in the cold. One exception runs the other way: Zelpio got about 12 hours from its Vespera 3. ## Field of view: the difference you’ll notice first The biggest practical split isn’t price. It’s how much sky each scope frames. The Seestars and Vesperas see 1.6–4° of sky in one shot. Unistellar sees about 0.75° × 0.56°, less than a third of the width of a Seestar S50 Pro’s frame. Native field of view How much sky the main camera frames in one shot (bar length = area in square degrees). The full Moon is about 0.5° across.

Try any target in the [framing calculator](https://smarttelescopereview.com/tools/fov-calculator/). That decides what you can photograph. The Andromeda Galaxy, about 3° long, fits in one S30 Pro frame and needs two mosaic panels on an S50 Pro or Vespera 3, which both brands’ apps can capture automatically. On a Unistellar it would take a 5 × 3 grid, and Unistellar has no mosaic mode, so in practice you get the core. The Pleiades, about 110 arcminutes across, also overflow a Unistellar frame. Narrow fields aren’t all bad. Unistellar’s 0.93″ per pixel on the Odyssey and 1.33″ on the eQuinox 2 put far more pixels on small galaxies, planetary nebulae and globular clusters than a Seestar’s 2.30″ (S50 Pro) or 3.74″ (S30 Pro). Jupiter comes out roughly 34–48 pixels across on a Unistellar versus about 12–20 on the Seestars. Check any target against any scope in the [framing calculator](https://smarttelescopereview.com/tools/fov-calculator/#target=m31&scope=unistellar-odyssey). ## Light pollution and filters This is where ZWO pulls ahead for suburban buyers. A dual-band filter passes the H-alpha and OIII light that emission nebulae give off and blocks most skyglow, and every Seestar has one built in. Vaonis sells a [dual-band filter for the Vespera](https://www.amazon.com/dp/B0C33SNQ79?tag=smarttelescopereview.com-20) separately (Vaonis hasn’t confirmed this exact part on the newer models, so check before ordering). Unistellar offers no physical filter at all. It relies on software light-pollution reduction instead, which can’t isolate a nebula’s emission lines at capture the way a dual-band filter does. If your sky is Bortle 6 or brighter, that difference matters more than aperture for nebulae. Our [light pollution guide](https://smarttelescopereview.com/posts/smart-telescopes-light-pollution-city/) explains why, and [best filters for smart telescopes](https://smarttelescopereview.com/posts/best-filters-for-smart-telescopes/) lists what fits each brand. ## Mount and EQ mode All nine scopes are alt-az, which means the image slowly rotates during a long session and the software has to correct it. ZWO is the only brand of the three that lets you tilt the scope into an equatorial (EQ) mode, using the [TH10 head](https://www.amazon.com/dp/B0FN82SCJL?tag=smarttelescopereview.com-20) (S50 Pro) or the [TH10 and TC20 bundle](https://www.amazon.com/dp/B0FN82ZLHM?tag=smarttelescopereview.com-20) (S30 series). ZWO says EQ mode allows 60-second exposures. If you plan long projects on faint targets, read [EQ mode explained](https://smarttelescopereview.com/posts/smart-telescope-eq-mode-explained/) first. Vaonis answers the same need differently: the Vespera 3 and Pro 2 save a project and resume stacking automatically on later nights, so you can build long integrations across several sessions. ## Build, battery, warranty and software Vaonis is clearly ahead on longevity promises. Five years of warranty on the Vespera 3 and Pro 2 beats two years at ZWO and Unistellar. The 11-hour battery covers a full winter night, and both new Vesperas have automatic anti-fog and IP43 weather resistance. The Vespera Pro 2 also takes automatic master darks (Vaonis), something Zelpio found missing on the Vespera 3, where hot pixels can show. Reviewers raise a few practical points. Digital Camera World found the Vespera 3’s startup alignment took over five minutes but saw Andromeda’s dust lanes in about ten minutes (not a controlled test). Live Science found the S50 Pro’s included tripod very short and spotted typos in the Seestar app. Space.com reports early Odyssey Pro units shipped defocused and were recalled. BBC Sky at Night found the eQuinox 2’s images “a little soft.” Unistellar’s software has a strength the others don’t match: the citizen-science program, where owners contribute observations to NASA/SETI campaigns. For families and school groups, that’s a real reason to choose the brand. ## Which brand should you buy? Most buyers: ZWO Seestar. The S50 Pro has 50 mm of aperture, built-in filters, EQ mode, mosaics, a solar filter and a 9 h battery (ZWO) for about $999. Nothing from Vaonis or Unistellar comes close on value, which is also Space.com’s view: it names the S50 Pro its value pick. [Check the S50 Pro price](https://www.amazon.com/dp/B0HP1RDLVP?tag=smarttelescopereview.com-20). If weight or travel matters more, the S30 Pro has the widest field here at 1.65 kg. Our [S30 Pro vs S50 Pro](https://smarttelescopereview.com/posts/seestar-s30-pro-vs-s50-pro/) comparison helps you choose. Buyers who value build and support: Vaonis Vespera 3. If you’d rather pay more once and keep the scope for years, the five-year warranty, 11 h battery and multi-night projects are the reasons to buy it. Budget extra for a dual-band filter if you live under suburban skies. The Pro 2 suits people who crop into small targets; the Vespera II only makes sense at a clear discount. [Check the Vespera 3 price](https://www.amazon.com/dp/B0GY1PT485?tag=smarttelescopereview.com-20). Small galaxies, science and sharing: Unistellar. The eQuinox 2 has the most aperture per dollar in this group and is Space.com’s best overall pick. The Odyssey is the easiest to run thanks to autofocus. For star parties and outreach, the Odyssey Pro’s Nikon eyepiece is the feature people remember. [Check the eQuinox 2 price](https://www.amazon.com/dp/B0BRNSWXLS?tag=smarttelescopereview.com-20). Bigger budgets and a permanent backyard: none of these three.

For value, yes. The Seestar S50 Pro has the same class of 50 mm aperture and an 8.3 MP sensor, plus a built-in dual-band filter, EQ mode and an included solar filter, for about $999. The Vespera 3 costs about $2,490 and adds Vaonis' flat-field optics, an 11 h battery and a five-year warranty, but no EQ mode or built-in filters. ### Is Unistellar worth the extra money over a Seestar? Only if you want what Unistellar does differently: 85–114 mm of aperture for small, faint galaxies, autofocus on the Odyssey, an electronic Nikon eyepiece on the Odyssey Pro and eVscope 2, and citizen-science campaigns. For wide nebulae, Andromeda and the Sun, a Seestar frames more of the sky for far less. ### Which smart telescope brands have an EQ mode? Of these three, only ZWO. The Seestar S30 Plus, S30 Pro and S50 Pro support EQ mode with ZWO's TH10 head (plus the TC20 tripod on the S30 models). Vaonis and Unistellar scopes are alt-az only and correct field rotation in software. ### Do Vespera or Unistellar telescopes need a subscription? We found no subscription for core features on Vaonis' or Unistellar's sites. Unistellar's app is free with no in-app purchases listed. ZWO's Seestar app is also free for core features; its Telescope Network remote access is a free beta trial. ### Which brand is best for planets? None of them is a planetary specialist. Unistellar's finer sampling puts Jupiter at roughly 34–48 pixels across versus about 12–20 on the Seestars, which helps, but Space.com calls the Odyssey line not ideal for planets. For planets, a traditional telescope such as the Celestron StarSense Explorer DX 130AZ is the better tool. ## Sources - [Space.com: The best smart telescopes (updated November 4, 2026)](https://www.space.com/best-smart-telescopes) · checked 2026-11-12 — Names the eQuinox 2 best overall, the eVscope 2 for larger budgets, the Seestar S50 Pro for value on small budgets and the Vespera II as its mid-range pick. - [Vaonis: Compare Vespera models](https://vaonis.com/pages/compare) · checked 2026-11-12 — Lists Vespera specs and warranties, and marks the original Vespera Pro as a legacy, discontinued model. - [Unistellar: Compare telescopes](https://www.unistellar.com/compare/) · checked 2026-11-12 — Unistellar's specs for the Odyssey, Odyssey Pro, eQuinox 2 and eVscope 2, including field of view, battery and limiting magnitude. - [Digital Camera World: Vaonis Vespera 3 review](https://www.digitalcameraworld.com/optics/telescopes/vaonis-vespera-3-review) · checked 2026-11-12 — Saw Andromeda's dust lanes in about ten minutes (not a controlled test), found startup alignment took over five minutes, and measured 6 kg with the tripod. - [ZWO: Seestar S50 Pro product page](https://www.zwoastro.com/product/seestar-s50-pro/) · checked 2026-11-12 — 50 mm f/5.2 four-element ED apochromat, dual-band filter, EQ mode with the TH10 head and up to 9 h of battery (ZWO lab figure). - [BBC Sky at Night: Unistellar Odyssey Pro review](https://www.skyatnightmagazine.com/reviews/unistellar-odyssey-pro) · checked 2026-11-12 — Rated it 4.5 out of 5; magnets hold the dust cap and solar filter, battery lasts about 5 hours. ## Get new guides by e-mail One short e-mail when Smart Telescope Review publishes a new guide.
