S30 Size 210*140*80 (mm)
EVA Hardshell Case 300*185*100 （mm）
The body weight of Seestar S30 is 1.65kg. The total weight of the S30 body, tripod, and EVA hard-shell case is only 2.12kg.
The sensor of Seestar S30 is Starlight-grade Sony IMX662, with a 1/2.8 inch format and a resolution of 1080*1920. The diagonal length is 6.46mm. The S30 boasts high sensitivity and low noise for better night performance.
Seestar S30 is a triplet complex achromatic APO (including one piece of low dispersion ED glass) with excellent chromatic aberration control. The aperture of the tele lens is 30mm, focal ratio F5. Focal length 150mm. The imaging performance is as good as a professional refractor of the same aperture.
The wide-angle FOV for the Seestar S30 is 23.2°, the tele FOV is 2.46°.
Seestar S30 comes with built-in 64GB eMMC storage, providing approximately 50GB of available space for data storage.
Recommended operating temperature: -10°C to 40°C, charging temperature: 0°C to 40°C
Stargazing Mode: Can photograph deep sky objects.
Scenery Mode: Can photograph landscapes or animals.
Solar Systerm Mode: Can photograph the sun, moon, etc., and will automatically turn on tracking.
S30 focusing distance is 6m~infinity.
Seestar S30 has three built-in filters: UV/IR Cut filter, dark filter, and astronomical light pollution filter (OIII 30nm/Hα 20nm).
Seestar S30 also comes with a magnetic solar filter, which can be used for solar photography.
Telephoto: Sony IMX585 (1/1.2"), portrait orientation
Wide-angle: Sony IMX586 (1/2"), portrait orientation
In telephoto mode, the following three filters are available:
UV/IR-Cut Filter
Duo-Band Filter (OIII 30 nm / Hα 20 nm)
Dark Filter (for dark frames)
Yes. The S30 Pro uses a professional 4-element apochromatic optical design, including one ED glass element.
From 6 m to infinity.
The wide-angle camera does not support filter switching. However, the module includes an astronomy-optimized IR-cut filter, designed to effectively preserve Hα (656 nm) signals.
The wide-angle camera supports autofocus, and users can select any focus area.
The built-in IR-cut filter of the wide-angle camera is already optimized to fully retain the 656 nm Hα band, making additional LP filters unnecessary.
To achieve optimal wide-field astrophotography performance, the S30 Pro uses pixel binning and a 16:9 aspect ratio at 4K resolution. As a result, the effective pixel size becomes 1.6 μm, with a final resolution of 3840 × 2160.
Yes. Both models share the same dimensions: 210 mm × 140 mm × 80 mm
The S30 Pro weighs 1.65 kg, making it easy to carry for outdoor use.
Yes, it uses the same 3/8"-16 tripod thread.
The built-in battery has a capacity of 6000 mAh.
According to ZWO laboratory tests, battery life can reach up to 6 hours.
The internal storage capacity is 128 GB.
Yes. In Scenery Mode, the device can track targets during daytime operation.
The S30 Pro offers four modes:
Stargazing Mode
Milky Way Mode
Solar System Mode
Scenery Mode
Milky Way and Star Trail shooting are currently exclusive to the S30 Pro.
At present, the S30 Pro does not apply dark-frame calibration. Instead, it uses RAW intelligent noise reduction.
Scheduled shooting can be configured during the daytime. As long as the shooting task is issued before the capture time, the device can remain in standby mode with low power consumption until the task begins.
Yes. Please note that Star Trail mode does not generate FITS files.
By adding the device to SkyNet, users can remotely control Seestar across regions, including:
Browsing the object library
Automatic target acquisition and imaging
Real-time preview and progress monitoring
Detailed instructions are available in the in-app tutorials.
Yes. The S30 Pro supports horizontal and vertical Milky Way mosaics, with output resolution of up to 8K.
Milky Way imaging is one of the key strengths of the S30 Pro. The Seestar App introduces a dedicated Milky Way Mode, featuring:
Real-time image stacking
Intelligent foreground separation
Milky Way mosaics
Star trail shooting
These capabilities allow the S30 Pro to significantly outperform most smartphones in astrophotography. In addition, the astronomy-optimized IR-cut filter effectively preserves Hα signals, which most smartphones cannot achieve.
When shooting the Milky Way in wide-angle mode, the S30 Pro automatically detects and locks onto foreground elements. The system intelligently separates the sky from the landscape— keeping stars sharp and well-tracked, while preserving natural detail and depth in the foreground— allowing both the sky and the Earth to shine within a single frame.
Supports both horizontal and vertical mosaics, with output quality up to 8K resolution.
