By [Smart Telescope Review Editorial Team](https://smarttelescopereview.com/about/) · Updated November 12, 2026 · [How we score](https://smarttelescopereview.com/how-we-research/) We haven't tested this telescope ourselves. Our score comes from manufacturer specs, independent reviews (named where we cite a test result) and owner reports. ## The verdict The S30 Plus replaces the original S30 as ZWO's entry model: the same 30 mm four-element apochromat as the S30 Pro, a 2K SmartSens sensor instead of 4K Sony, and fewer wide-angle tricks, for $190 less. For a first smart telescope that lives in a backpack and shows the Moon, the Sun, the Orion Nebula and bright clusters, it's the cheapest sensible Seestar. If you care about resolution, Milky Way panoramas or mosaics, the S30 Pro is worth the extra. ### What we like - $474 for a complete kit: telescope, mini tripod, protective case and a magnetic solar filter - Built-in duo-band (H-alpha/OIII) filter for emission nebulae from light-polluted skies - Same 30 mm f/5.3 four-element apochromatic lens and 1.65 kg body as the S30 Pro - EQ mode with the optional TH10 head and TC20 tripod for longer, rotation-free exposures ### Watch out for - 2K (1440 × 2560) telephoto output versus the S30 Pro's 4K sensor - No wide-angle mosaic stitching, Milky Way panorama, dual-camera capture or comet stacking (all on the S30 Pro) - 64 GB storage, about 45 GB usable - Launched November 10, 2026: no independent written reviews or long-term owner record yet ## Score breakdown Image quality & optics 6.8 Ease of use & app 8.6 Portability & build 9.2 Value 9 30 mm f/5.3 · Motorized alt-az + EQ mode · weighted 35/25/20/20 ## Seestar S30 Plus specs | Brand | ZWO | | --- | --- | | Type | Smart telescope | | Aperture | 30 mm | | Focal length / ratio | 160 mm, f/5.3 | | Optics | 4-element apochromatic refractor | | Sensor | SmartSens SC485SL (1/1.8-inch), 2K output | | Resolution | 2560 × 1440 px (3.7 MP) | | Pixel size / scale | 2.9 µm · 3.74″ per pixel | | Field of view | 2.66° × 1.5°.

Specs are compiled from manufacturer pages, Amazon listings and independent reviews, and may change with firmware or production runs. Confirm what's in the box (tripod, solar filter, case) on the Amazon page before buying. ## ZWO Seestar S30 Plus Smart Telescope video review [![](https://i.ytimg.com/vi/eA_Z6ewfHyM/hqdefault.jpg)](https://www.youtube.com/watch?v=eA_Z6ewfHyM) Video by AstroBackyard on YouTube. Independent creator content, shown as a reference. It is not part of our scoring. The Seestar S30 Plus is ZWO’s new entry-level smart telescope, launched on November 10, 2026 as the replacement for the original Seestar S30. It keeps the S30 Pro’s 30 mm f/5.3 four-element apochromatic lens and 1.65 kg body, swaps in a 2K SmartSens sensor, and ships with a mini tripod, a case and a magnetic solar filter. It costs about $474 on Amazon (Nov 12, 2026); check today’s price before you buy. We haven’t tested it ourselves, and because it’s two days old, nobody has published a written review yet. This page explains what’s known and where the gaps are; see [how we research](https://smarttelescopereview.com/how-we-research/) for our method. ## Who the S30 Plus is for (and who should skip it) It’s for first-time stargazers who want the cheapest current Seestar and a complete kit in one box: the Moon, the Sun (with the filter fitted), the Orion Nebula and bright star clusters, from a scope small enough for a backpack. Skip it if you want the best images a 30 mm Seestar can make. The [Seestar S30 Pro](https://smarttelescopereview.com/smart-telescopes/seestar-s30-pro/) has a 4K sensor, a wider field and wide-angle mosaics for $190 more. Skip it too if the scope will mostly sit in the backyard: the [Seestar S50 Pro](https://smarttelescopereview.com/smart-telescopes/seestar-s50-pro/) collects about 2.8 times the light. And if you want planets, no 30 mm smart scope is the right tool. ## Imaging in practice There’s no independent test of the S30 Plus yet, so read this section as informed expectation, not a verdict. The optics are shared with the S30 Pro, which reviewers have tested. BBC Sky at Night wrote that “planets are too small to show any detail, but we were able to capture Jupiter and its Galilean moons”, and Fstoppers described Jupiter as a small dot. Expect the same from the S30 Plus: the lens is identical, and so is the pixel scale (about 3.7 arcseconds per pixel), because ZWO’s 2560 × 1440 output is a crop of a sensor with the same 2.9 µm pixels. The real difference is field of view. The crop shrinks the frame to about 2.66° × 1.5°, against roughly 4° × 2.2° on the S30 Pro. The Andromeda Galaxy fits one S30 Pro frame; on the S30 Plus its full length overflows the frame, and ZWO hasn’t confirmed telephoto mosaics on this model. Try your own targets in the [FOV calculator](https://smarttelescopereview.com/tools/fov-calculator/#target=m31&scope=seestar-s30-plus). The built-in duo-band filter (OIII 30 nm, H-alpha 20 nm) is the feature that matters most from suburbs. It boosts emission nebulae such as the Orion and Rosette nebulae, and does nothing for galaxies. See what’s realistic under your sky with the [sky target checker](https://smarttelescopereview.com/tools/sky-target-checker/#scope=seestar-s30-plus&bortle=6). ## App and workflow The S30 Plus runs on the same Seestar app as the rest of the range, with no subscription for core features. You pick a target, the scope finds it and starts live stacking, and the picture improves on your phone as frames add up. It connects over 5 GHz or 2.4 GHz Wi-Fi. Storage is 64 GB, of which about 45 GB is usable, so plan to offload images to your phone or computer regularly. ZWO rates the 6,000 mAh battery at up to six hours with anti-dew off; expect less on cold nights. AstroBackyard published a video on the S30 Plus on launch day; it’s embedded on this page if you want to see the scope and app in use. ## What you’ll need beyond the box - **EQ mode.** Optional. ZWO recommends its [TH10 head and TC20 tripod bundle](https://www.amazon.com/dp/B0FN82ZLHM?tag=smarttelescopereview.com-20) (about $180), or the [TH10 head](https://www.amazon.com/dp/B0FN82SCJL?tag=smarttelescopereview.com-20) and [TC20 tripod](https://www.amazon.com/dp/B0FN8412CW?tag=smarttelescopereview.com-20) separately. A [Leftfoto tripod leveler](https://www.amazon.com/dp/B092M5G7VD?tag=smarttelescopereview.com-20) makes polar alignment easier. Our [EQ mode explainer](https://smarttelescopereview.com/posts/smart-telescope-eq-mode-explained/) covers whether you need it. - **Power.** A USB-C power bank such as the [Anker 737](https://www.amazon.com/dp/B09VPHVT2Z?tag=smarttelescopereview.com-20) or the cheaper [UGREEN Nexode 20,000 mAh](https://www.amazon.com/dp/B0C3GTMX5M?tag=smarttelescopereview.com-20) keeps you going past the internal battery. - **Solar.** The filter is included. Add [ISO 12312-2 eclipse glasses](https://www.amazon.com/dp/B08GB3QC1H?tag=smarttelescopereview.com-20) for your own eyes. - **Dew and travel.** A [Neo3D dew shield](https://www.amazon.com/dp/B0DTC41H97?tag=smarttelescopereview.com-20) and a [CASEMATIX hard case](https://www.amazon.com/dp/B0H2CB984L?tag=smarttelescopereview.com-20) are sold for the S30 and S30 Pro; confirm S30 Plus fit before ordering. - **A red flashlight**, such as the [Celestron Night Vision](https://www.amazon.com/dp/B0000665V5?tag=smarttelescopereview.com-20), for finding cables in the dark. ## How it compares Score vs. Amazon price Each dot is one telescope: our research-based score against its Amazon price on Nov 12, 2026 (price axis compressed).

Our [S30 Plus vs S30 Pro](https://smarttelescopereview.com/posts/seestar-s30-plus-vs-s30-pro/) comparison goes feature by feature. The [Dwarf Mini](https://smarttelescopereview.com/smart-telescopes/dwarf-mini/) is a little cheaper and much lighter at 840 g, but it has a 2 MP sensor and no tripod or case in the box. For more options at this price, see our [best budget smart telescopes](https://smarttelescopereview.com/posts/best-budget-smart-telescopes/). ## Bottom line The S30 Plus is the cheapest sensible way into the Seestar system: a good lens, a duo-band filter, a solar filter and a tripod for about $474. What it lacks is a track record, so wait for the first independent reviews if you can. If you’re ready now and want the full 30 mm experience, the S30 Pro is worth the extra; if price is what matters, [check the S30 Plus price on Amazon](https://www.amazon.com/dp/B0HMW9GDGJ?tag=smarttelescopereview.com-20).

They share the same 30 mm f/5.3 four-element lens and 1.65 kg body. The S30 Plus uses a 2K SmartSens SC485SL sensor instead of the S30 Pro's 4K Sony IMX585, has 64 GB of storage instead of 128 GB, and drops wide-angle mosaic stitching, Milky Way panoramas, simultaneous dual-camera capture and comet stacking. It costs about $190 less on Amazon (Nov 12, 2026). ### Does the Seestar S30 Plus come with a solar filter? Yes. ZWO includes a magnetic solar filter, a mini tripod and a protective case. Fit the solar filter before you point the scope anywhere near the Sun, every time. ### Can the Seestar S30 Plus photograph planets? Only as small discs. At about 3.7 arcseconds per pixel, Jupiter comes out roughly 12 pixels across: enough to see the disc and its moons, not cloud-belt detail. Reviewers found the same with the S30 Pro, which uses the same lens. ### Does the S30 Plus replace the original Seestar S30? Yes. High Point Scientific lists the original S30 as discontinued, and ZWO's old S30 page now redirects to the S30 Plus. ### Do I need the TH10 head and TC20 tripod? Not to start. The S30 Plus works in alt-az mode on the included mini tripod. ZWO says 60-second exposures are only available in EQ mode, which needs the TH10 head and TC20 tripod (sold separately). ## Sources - [amazon.com](https://www.amazon.com/dp/B0HMW9GDGJ?tag=smarttelescopereview.com-20) - [zwoastro.com](https://www.zwoastro.com/product/seestar-s30-plus/) - [smartsenstech.com](https://www.smartsenstech.com/en/sl_products) - [highpointscientific.com](https://www.highpointscientific.com/zwo-seestar-s30-all-in-one-smart-telescope) Not sold yet? ## Alternatives to the Seestar S30 Plus ![DWARFLAB Dwarf Mini Smart Telescope](https://smarttelescopereview.com/_astro/dwarf-mini.Bla2t7aX_Z2fEVPh.webp) ### [DWARFLAB Dwarf Mini Smart Telescope](https://smarttelescopereview.com/smart-telescopes/dwarf-mini/) 7.8 - 30 mm f/5 - 2.13° × 1.2° field - 1.9 lb - EQ mode - Dual-band filter Hikers, travelers and budget buyers who want the smallest, lightest smart telescope for the Moon, the Sun, bright nebulae and wildlife. $$$$ Budget Price tier: Budget Amazon price, Nov 12, 2026 [Check price on Amazon](https://www.amazon.com/dp/B0GT3VFN84?tag=smarttelescopereview.com-20)[Read the full review](https://smarttelescopereview.com/smart-telescopes/dwarf-mini/) ![DWARFLAB Dwarf 3 Smart Telescope](https://smarttelescopereview.com/_astro/dwarf-3.BTcvoQNe_20D8dL.webp) ### [DWARFLAB Dwarf 3 Smart Telescope](https://smarttelescopereview.com/smart-telescopes/dwarf-3/) 8.2 - 35 mm f/4.3 - 2.93° × 1.65° field - 3 lb - EQ mode - Dual-band filter Owners who want one compact device for deep-sky imaging, the Moon and Sun, and daytime wildlife or landscape photography, with 4K resolution under $600. $$$$ Budget Price tier: Budget Amazon price, Nov 12, 2026 [Check price on Amazon](https://www.amazon.com/dp/B0FHP6K4BK?tag=smarttelescopereview.com-20)[Read the full review](https://smarttelescopereview.com/smart-telescopes/dwarf-3/) ![ZWO Seestar S30 Pro Smart Telescope](https://smarttelescopereview.com/_astro/seestar-s30-pro.DqtA63or_17JhhU.webp) ### [ZWO Seestar S30 Pro Smart Telescope](https://smarttelescopereview.com/smart-telescopes/seestar-s30-pro/) 8.5 - 30 mm f/5.3 - 3.99° × 2.24° field - 3.6 lb - EQ mode - Dual-band filter Travelers and beginners who want the most capable ultra-portable smart telescope: wide nebulae, the Milky Way, the Moon and the Sun from a 1.65 kg scope. $$$$ Mid-range Price tier: Mid-range Amazon price, Nov 12, 2026 [Check price on Amazon](https://www.amazon.com/dp/B0GYX9GSVX?tag=smarttelescopereview.com-20)[Read the full review](https://smarttelescopereview.com/smart-telescopes/seestar-s30-pro/) [Compare all 15 telescopes →](https://smarttelescopereview.com/smart-telescopes/) ## Helpful guides [Top picks ### The 7 Best Smart Telescopes of 2026: Ranked for Backyard, Travel and Budget The best smart telescopes of 2026, ranked: Seestar S50 Pro, S30 Pro, Dwarf 3, Vespera 3, eQuinox 2 and Origin Mark II, with real prices and honest trade-offs.
