Seestar S30 Plus: Specs, Price, Release Date and S30 Pro Comparison
Update — November 10, 2026: ZWO has officially launched the Seestar S30 Plus. This article now reflects the official specifications, price and availability. The list price is $499 / €499, with an introductory price of $469 in the US and €474 on ZWO's EU store.
The Seestar S30 Plus is ZWO's new mid-range compact smart telescope. It sits between the original S30 and the S30 Pro: it keeps the S30 Pro's 160 mm APO optics and adds a wide-angle camera for Milky Way shots, but it captures 2K images instead of 4K and drops some of the Pro's advanced wide-angle features. Here are the official specs, the price, what's missing compared with the S30 Pro, and who each model is for.
- Main camera: 30 mm, 160 mm f/5.3, 4-element apochromatic optics, 3° field of view
- Sensors: SmartSens SC485SL (1/1.8") telephoto and Sony IMX586 (1/2") wide-angle, both with 1440 × 2560 output
- Wide-angle camera: 6 mm f/1.75, 43.5° field of view: Milky Way, star trails and meteors
- Same body as the S30 family: 1.65 kg, 6000 mAh battery, EQ mode supported, now with NFC
- Price: $499 / €499 list, introductory $469 (US) and €474 (EU store)
What the S30 Plus can't do (vs the S30 Pro)
The S30 Plus shares the S30 Pro's optical design, but ZWO reserves several advanced wide-angle features for the Pro. This is the most important difference to understand before buying.
| Feature | S30 Plus | S30 Pro |
|---|---|---|
| Wide-field astrophotography (Milky Way, star trails, meteors) | Yes | Yes |
| Simultaneous dual-camera capture | No | Yes |
| Wide-angle mosaic stitching | No | Yes |
| One-tap Milky Way arch | No | Yes |
| 4K output | No (2K) | Yes |
| NFC quick connection | Yes | Yes |
| Equatorial mode | Yes | Yes |
In practice, the S30 Plus can still shoot the Milky Way, star trails and meteors with its wide-angle camera. What it can't do is run both cameras at the same time, stitch wide-angle panoramas, or build the full Milky Way arch automatically.

S30 vs S30 Plus vs S30 Pro
The S30 Plus shares the S30 Pro's optics and pixel size, but uses a smaller sensor cropped to 2K. Its field of view is wider than the original S30's and narrower than the S30 Pro's. That is why ZWO calls it "a wider view of the sky": the comparison is with the S30.
| Seestar S30 | Seestar S30 Plus | Seestar S30 Pro | |
|---|---|---|---|
| Telephoto sensor | Sony IMX662 (1/2.8") | SmartSens SC485SL (1/1.8") | Sony IMX585 (1/1.2") |
| Wide-angle sensor | — | Sony IMX586 (1/2"), cropped | Sony IMX586 (1/2") |
| Resolution | 1920 × 1080 | 1440 × 2560 | 3840 × 2160 |
| Focal length | 150 mm | 160 mm | 160 mm |
| Telephoto field of view | 2.46° | 3° | 4.6° |
| Wide-angle field of view | 23.2° | 43.5° | 63° |
| Milky Way / star trails with wide camera | No | Yes | Yes |
| Simultaneous dual-camera capture | No | No | Yes |
| Wide-angle mosaic / Milky Way arch | No | No | Yes |
| Storage | 64 GB | 64 GB | 128 GB |
| Battery | 6000 mAh | 6000 mAh | 6000 mAh |
| Weight | 1.65 kg | 1.65 kg | 1.65 kg |
| List price (US) | $399 (sold out) | $499 ($469 intro) | $699 |
The pixel size is 2.9 µm on all three models. On targets that fit in the frame, the S30 Plus should resolve the same detail as the S30 Pro. Large nebula complexes and wide mosaics are where the Pro's bigger sensor still wins, although ZWO's own teaser shows the full Andromeda Galaxy fitting in the S30 Plus's portrait frame.
First images and what the early presentation showed
Before launch, an early hands-on presentation showed raw and edited images taken with the S30 Plus under Bortle 4–5 skies, and the results look very close to the S30 Pro.
Sample images shown:
| Target | Total integration | Sub-exposures |
|---|---|---|
| Orion Nebula (M42) | 30 min | — |
| Andromeda Galaxy (M31) | 4.5 h | 30 s |
| Elephant's Trunk Nebula | 3.5 h | 60 s |
| Ghost of Cassiopeia (IC 63) and Gamma Cassiopeiae | about 70 min | — |
| Triangulum Galaxy (M33) | not stated | — |
| Veil Nebula (eastern section) | not stated | — |
Key points from the presentation:
- Low noise and good star correction to the edges, thanks to the 4-element optics and the smaller sensor.
- Different color profile from the S30 Pro. Galaxy arms and colors stand out more, and the difference is visible in RAW files too, not just after editing.
- Same mechanics as the S30. Note that ZWO says 60 s sub-exposures require EQ mode with accurate polar alignment.
- EQ mode is worth it. With an optional wedge, the telescope tracks on one axis and avoids field rotation on long sessions.
- Lunar detail matches the S30 Pro. Same aperture and optics mean craters resolve the same way.
Note: we could not identify all targets with certainty from the presentation audio. Integration times are as stated by the presenter.

Who is the S30 Plus for?
The S30 Plus is the best value in the S30 line if you want S30 Pro optics and a Milky Way camera, and don't need the Pro's advanced wide-angle features.
Choose the S30 Plus
If you want deep-sky imaging and single-frame Milky Way, star trail and meteor shots in one compact kit, and 2K output is enough for sharing and moderate-size prints.
Choose the S30 Pro
If you want 4K files, simultaneous dual-camera capture, wide-angle mosaics and the one-tap Milky Way arch, a wider 4.6° field and 128 GB of storage.
Upgrading from the S30?
You get a larger main sensor, a 3° field instead of 2.46°, NFC, and a wide camera that can finally shoot the Milky Way.
FAQ
What is the Seestar S30 Plus?
It is ZWO's compact smart telescope positioned between the S30 and the S30 Pro. It combines a 30 mm f/5.3 apochromatic telephoto with a 43.5° wide-angle camera, both recording 2K (1440 × 2560) images.
When was the Seestar S30 Plus released?
ZWO launched the S30 Plus on November 10, 2026. Pre-orders on the EU store ship within 7 days.
How much does the S30 Plus cost?
The list price is $499 / €499. At launch it is offered at $469 in the US and €474 on ZWO's EU store.
What is the difference between the S30 Plus and the S30 Pro?
Both share the same 30 mm / 160 mm apochromatic optics, battery and weight. The S30 Pro adds 4K output, a 4.6° field, a 63° wide camera, 128 GB of storage, simultaneous dual-camera capture, wide-angle mosaics and the one-tap Milky Way arch. The S30 Plus costs about $200 less.
Can the S30 Plus photograph the Milky Way?
Yes. Its wide-angle camera captures the Milky Way, star trails and meteors under dark skies. It does not support wide-angle mosaic stitching or the one-tap Milky Way arch, which are S30 Pro features.
Does the S30 Plus support simultaneous dual-camera shooting?
No. The S30 Plus has two cameras, but it cannot use them at the same time. Simultaneous dual-camera capture is reserved for the S30 Pro and S50 Pro.
Does the S30 Plus support EQ mode?
Yes. It is an alt-azimuth telescope that also supports equatorial mode with an optional wedge. ZWO notes that 60-second exposures require EQ mode with accurate polar alignment.
What's in the box?
The telescope, a magnetic solar filter, an aluminum alloy tripod, a carrying case with shoulder strap, a USB-C cable, stickers and a quick start guide.
