ZWO Seestar S30 Pro review

Our verdict

The Seestar S30 Pro is the sweet spot of ZWO's range for a lot of people: the 4K camera pair of the S50 Pro, a 1/1.2-inch Sony IMX585 sensor, a 4-element apochromatic lens and anti-dew control in a 1.65 kg body, for $699 and in stock. What you give up is aperture: 30 mm.

Great if

  • you want wide nebulae, star fields and Milky Way mosaics more than small galaxies
  • you travel by plane or hike: ZWO answers "can I bring it on a plane?" in its FAQ
  • you want 4K images without paying $999

Skip it if

  • planets or small galaxies are the goal (about 3.8″ per pixel)
  • you hate buying extras: Equatorial Mode needs the TH10 head and TC20 tripod ($189 as a bundle)
  • you want the longest battery life: ZWO states 6,000 mAh, not hours

What a night with it looks like

The S30 Pro is built for wide views. Its telephoto field is 4.6°, almost twice that of the S30, so the whole Orion sword, the Heart and Soul nebulae or the North America Nebula fit in one frame. The 63° wide camera handles one-tap Milky Way mosaics up to 8K and star trails, and ZWO's Freeze the Ground mode keeps the landscape sharp while the sky moves.

Three filters are built in: a dark field filter for calibration, a UV/IR cut filter, and a duo-band light pollution filter for OIII and Hα, the one that makes emission nebulae pop from a suburban yard. The active anti-dew control is a real comfort on humid nights; dew on the lens is the most common way a session ends early.

The catch

Thirty millimeters is small. Our computed image scale is about 3.8″ per pixel, so galaxies like M51 or M81 come out small and soft, and planets are not its job. If galaxies are your thing, the S50 Pro is the better buy.

Like every Seestar bought from ZWO's US store, opened returns cost a 10% restocking fee plus return shipping. ZWO's FAQ also notes that Equatorial Mode needs additional accessories.

Questions about the Seestar S30 Pro

Seestar S30 Pro or S50: which one?

The S30 Pro has the better camera (4K, larger sensor), a wide-angle lens and a wider 4.6° field; the S50 has more aperture (50 vs 30 mm) and a finer image scale for small targets. The S50 was cheaper at $549 but sold out on the official US store. See our S30 Pro vs S50 head-to-head.

Can the Seestar S30 Pro photograph planets?

ZWO's FAQ answers the question, and the numbers set the expectations: 30 mm of aperture and about 3.8″ per pixel show Jupiter and Saturn as small discs. For planets, a longer focal length helps more than a better sensor.
