ZWO Releases Seestar S30 Plus Smart Telescope for $499

ZWO has released the Seestar S30 Plus, a $499 smart telescope that slots between the $399 S30 and the $699 S30 Pro in the company’s fast-expanding lineup, offering beginners a one-step workflow from pointing at the sky to a finished, shareable image, livescience.com reported.

The new model arrived less than a year after the S30 Pro debuted in January 2026 and the S50 Pro in August, meaning buyers now face three new Seestar options in under twelve months, according to scopetrader.com. A Black Friday promotion beginning November 10, 2026, at 14:00 UTC takes 5% off both the S30 Plus and the S30 Pro, while the S50 Pro stays at full price, scopetrader.com reported.

S30 Plus features upgraded optics and higher resolution

The S30 Plus keeps the 30mm aperture and 160mm focal length of its siblings but upgrades to four-element apochromatic optics with ED glass, a step up from the S30’s three-element design, designed to tighten star shapes and cut halos, galactic-hunter.com reported.

Both of its cameras output 2K images at 1440 x 2560, roughly 3.7 megapixels, with 64GB of storage and a 6000 mAh battery rated for up to six hours, galactic-hunter.com and scopetrader.com reported.

Design and setup

The unit weighs 3.63 pounds (1.65 kg) and measures 8.3 x 5.5 x 3.2 inches, coming in a padded carry case with a small tripod, a solar filter, a one-meter USB-A to USB-C cable and a shoulder strap; the full kit weighs 4.89 pounds (2.22 kg), livescience.com reported.

Setup requires a single power button and a USB-C port, and the included anti-dew heater handled mild to moderate humidity in testing, though livescience.com noted faint condensation on dewier nights.

What the dual cameras capture

The telephoto camera handles deep-sky objects while a 6mm wide-angle camera covers constellations, star trails, the Milky Way and daytime shots, galactic-hunter.com reported. The main camera carries three built-in filters — a UV/IR-cut, a duo-band filter isolating H-alpha and OIII for emission nebulae, and a dark-frame filter for calibration — plus the external solar filter for eclipse imaging, galactic-hunter.com reported.

In tests from a Bortle 4 backyard, the 160mm focal length filled the frame with the Andromeda Galaxy, the Pleiades and large emission nebulae like the North America and Eastern Veil, with visible nebulosity appearing after just 15 minutes of integration, livescience.com reported. Small planetary nebulae such as the Helix remained a limitation of the short focal length, livescience.com reported.

App features guide target selection and editing

The Seestar app guides users through target selection, showing altitude and coordinates for each object and recommending “Tonight’s Best” based on time and location, livescience.com reported. Its AI Enhance tools reduce stars, adjust curves and remove satellite trails, though testers wanted a dehaze slider and more responsive controls; raw files can also be exported for processing in dedicated software, livescience.com reported.

S30 Plus versus the Pro and alternatives

For a firm $500 budget, scopetrader.com judged the Plus a useful trade, but recommended the Pro’s 4K output, wider framing and 128GB storage if another $200 is within reach.

The 5% discount window opening November 10, 2026, is the next dated decision point for buyers weighing the Plus against the Pro.
