ZWO released the Seestar S30 Plus smart telescope for $499, filling the gap between the S30 and S30 Pro models with 2K image quality and dual cameras for beginners, livescience.com reported.
The device weighs 3.63 pounds and measures 8.3 by 5.5 by 3.2 inches. It ships inside a padded soft carry case with a small tripod, a solar filter, a USB charging cable, a shoulder strap, and a quick-start guide, bringing total travel weight to 4.89 pounds.
The hardware features a single power button and a USB-C port on the side. Turning on the unit triggers a double beep and illuminates a red battery indicator. Users sync the telescope with a smartphone or tablet via the companion application.
The application interface organizes celestial objects into sections such as Tonight’s Best, galaxies, nebulas, and star clusters. Selecting an object displays its current altitude and coordinates. The software automatically applies filters and tracking parameters, though users retain manual override options.
An anti-dew heater manages mild to moderate humidity during evening sessions.
Testing conducted in a Bortle 4 region utilized 60-minute integration times prior to moonrise. The 160mm focal length suits larger apparent targets like the Andromeda Galaxy, the Pleiades, and the North America Nebula.
Atmospheric cloud cover during the Andromeda Galaxy session caused stacking difficulties near the 57-minute mark. Planetary nebulas appeared small within the 160mm field of view, demonstrating the optical limitations of the hardware for distant, compact subjects.
| Celestial Target | Integration Time | App Editing Features Used |
|---|---|---|
| Pleiades (M45) | 60 minutes | Star reduction, blue haze adjustment |
| Andromeda Galaxy (M31) | 57 minutes | Outer arm detail stacking, brightness curve |
| North America Nebula | 60 minutes | Hydrogen gas contrast boost |
| Helix Nebula | 27 minutes | Color balance adjustment |
Buyers seeking higher-resolution output can select the ZWO Seestar S30 Pro, which delivers 4K images. Observers wanting to resolve smaller deep-sky objects can choose the ZWO Seestar S50 Pro, featuring a 260mm focal length and a 50mm aperture.
Consumers uninterested in digital imaging can purchase the Celestron StarSense Explorer LT 70AZ. That traditional optical setup connects to mobile devices for navigational guidance while preserving eyepiece observation.
