ZWO has expanded its Seestar smart telescope lineup with the new S30 Pro model, featuring dual cameras, 4K imaging, and improved automation.
ZWO (Zhejiang Weiguang Optoelectronic Technology) has introduced a new generation of compact digital telescopes: the Seestar S30 Pro. This new model builds upon the popular Seestar series, featuring upgraded optics, more sensitive sensors, enhanced astrophotography capabilities, and an even simpler process for observing the cosmos via smartphone.
This model is designed for both amateur astronomers just starting out and experienced users who need a lightweight, portable instrument for imaging nebulae, galaxies, star clusters, the Moon, the Sun, and wide-field panoramas of the night sky.
A new stage in the development of the Seestar series
The company’s first popular smart telescope, the Seestar S50—released in 2023—demonstrated strong demand for fully automated observation systems. Users did not need a separate camera or mount, complex polar alignment, or in-depth knowledge of astrophotography.
The Seestar S30 Pro builds on this concept but prioritizes compactness and versatility. Unlike the S50, which is geared more towards magnified imaging of deep-space objects, the S30 Pro offers a wider field of view and greater portability.
One of the main advantages of the Seestar S30 Pro is its dual-camera system:
Telescopic camera
Uses sensor:
- 8.3 MP resolution
- 4K image format
- field of view of about 4.6°
- Sony IMX585
It is designed for shooting:
- nebulae;
- galaxies;
- star clusters;
- deep-space objects.
Wide-angle camera
Additional sensor:
- Sony IMX586
- 8.3 MP resolution
- field of view of approximately 63°
It allows you to shoot:
- Milky Way;
- large constellations;
- night landscapes;
- the movement of the stars.
This approach makes the S30 Pro a more versatile tool compared to previous compact models.
1. Dual camera: telephoto and wide-angle lenses in a single body
One of the major updates is the dual-sensor system:
telescopic camera based on the Sony IMX585;
wide-angle camera with a Sony IMX586 sensor.
Both cameras provide a resolution of approximately 8.3 megapixels (4K). This approach allows a single device to be used for multiple tasks simultaneously:
- imaging of deep-space objects;
- photographs of the Milky Way;
- large areas of the sky;
- constellations;
- night landscapes.
2. Improved APO optical system
The Seestar S30 Pro features a four-element apochromatic objective lens with ED glass.
This design helps to:
- reduce color halos around bright stars;
- increase image sharpness;
- improve detail rendering across the entire frame
For a compact digital telescope, this is a significant step forward compared to previous models.
3. Fully automatic operation
Like other Seestar models, the S30 Pro operates on a "take it out, turn it on, and start shooting" basis.
The telescope autonomously performs:
- automatic pointing (GoTo);
- object tracking;
- focusing;
- combining multiple frames;
- image processing.
All operations are performed via the Seestar app on a smartphone or tablet.
4. Equatorial mode support
The new product has gained the capability to operate in equatorial mode via additional equipment.
This makes it possible to compensate for the Earth's rotation and obtain higher-quality long-exposure astrophotographs.
How does the Seestar S30 Pro differ from the Seestar S50?
Despite being a newer model, the S30 Pro is not a direct replacement for the S50.
Seestar S50:
- better suited for small deep-space objects;
- has a longer focal length;
- better suited for galaxies and compact nebulae.
Seestar S30 Pro:
- lighter and more mobile;
- captures large areas of the sky better;
- more convenient for travel;
- features more modern sensors and a wide-angle camera.
Who is the Seestar S30 Pro designed for?
The new telescope will be of particular interest:
- beginners in astrophotography;
- owners of small apartments with no space for large equipment;
- for travelers;
- enthusiasts of Milky Way photography;
- for those who want to capture beautiful images of space without complex setup.
Conclusion
The ZWO Seestar S30 Pro is not merely a scaled-down version of the S50, but represents a distinct direction in the evolution of smart telescopes. The manufacturer has prioritized portability, a wide field of view, and maximum automation.
For beginner astronomers, this model can be one of the most convenient ways to get started with astrophotography, while for experienced users, it offers a compact tool for quick observation sessions and travel.
Following the success of the Seestar S50, the new model demonstrates that the smart telescope market continues to evolve rapidly, with an increasing number of professional astrophotography features becoming accessible to owners of standard smartphones.
