Frequently Asked Questions
The S30 Plus is a ready-to-use smart telescope for everything from city balconies and backyards to outdoor adventures.
- City balconies and backyards: The built-in dual-narrowband light pollution filter (OIII/Hα) works with live stacking to help you capture deep-sky objects such as nebulae and star clusters, even under city light pollution.
- Outdoors: The Active Anti-Dew Control function helps prevent fogging during long outdoor sessions. Even without a local Wi-Fi network, you can connect your phone directly to the telescope’s own Wi-Fi and shoot using the Seestar App installed on your phone.
The S30 Plus works automatically by default: choose a target and let it handle the rest.
- Automatic target finding: Seestar’s proprietary algorithm finds and tracks celestial objects, recognizes targets, aligns images, and adjusts focus. The entire imaging process is controlled in the app, with no need to enter settings manually.
- Tap a target to start: In Solar System Mode, select the Sun, Moon, or a planet. The device focuses, starts tracking, and begins imaging automatically. For deep-sky and wide-field targets, simply select a target in SkyAtlas; there is no need to set focal length or exposure time.
- Optional advanced controls: Adjust exposure time, filter selection, and zoom as needed.
Beginners can start shooting without adjusting settings, while experienced users can fine-tune them in the app.
Compared with the S30, the S30 Plus brings six key upgrades:
- Wide-field astrophotography: The S30 can capture deep-sky objects, the Moon, and planets, as well as terrestrial scenes. The S30 Plus adds wide-field imaging for the Milky Way, star trails, and meteors.
- Upgraded sensors:
Telephoto: S30: 1/2.8-inch 2 MP → S30 Plus: 1/1.8-inch 3.68 MP.
Wide-angle: S30: 1/3-inch → S30 Plus: 1/2-inch, with the sensor orientation changing from landscape to portrait to help fit more of the Milky Way’s band in a single frame. - Higher resolution: 1080p → 2K, giving you more room for post-processing, viewing details when zoomed in, and reframing your images.
- Upgraded optics: A three-element apochromatic lens → a four-element apochromatic lens.
- Longer focal length: Telephoto aperture / focal length: 30 mm / 150 mm → 30 mm / 160 mm. Together with the larger sensor, the telephoto field of view increases from 2.46° to 3°, making it easier to frame deep-sky objects in a single shot.
- NFC connection: Tap a compatible phone against the device to connect, without manual pairing.
If you want to capture the Milky Way, star trails, or meteors, or would like the added detail of 2K imaging, the S30 Plus is worth considering.
The S30 Plus is the entry-level option and is approximately US$100 less than the S30 Pro at regular retail prices.
The S30 Pro offers a 1/1.2-inch 8.3 MP sensor, a 63° wide-angle field of view, 4K output, wide-angle stitching, one-tap Milky Way arch capture, and simultaneous dual-camera capture. It is better suited to a wider field of view, higher resolution, and frequent wide-field or dual-camera projects.
The two models share the same optical and lens design. The S30 Plus also features a four-element apochromatic lens, NFC connection, wide-field astrophotography, and approximately six hours of battery life.
Choose the S30 Plus if you want to capture the Milky Way and other wide-field scenes without extensive post-processing, or if you are looking for a gift or a way to explore astronomy with your family. Choose the S30 Pro if you prioritize creative output, 4K resolution, and a wider field of view.
- Telephoto: SC485SL, 1/1.8-inch, 1440 × 2560 (2K).
- Wide-angle: IMX586, 1/2-inch, 1440 × 2560 (2K, cropped).
The S30 Plus has 64 GB of internal storage. Approximately 45 GB is available for use because part of the capacity is occupied by the storage system and system files. Future system updates may affect the space available; actual capacity may vary.
- Dimensions: 210 mm high × 140 mm wide × 80 mm deep, with the telescope closed.
- Weight: 1.65 kg for the device, excluding the tripod.
Both are the same as the S30 Pro.
The S30 Plus comes with the telescope, a magnetic solar filter, an aluminum alloy tripod, astronomy stickers, a protective carrying case with shoulder strap, a USB-C cable, a quick guide, and a safety guide.
If you plan to use Equatorial Mode, we recommend the TH10 + TC20 tripod head and tripod bundle.
If you already own a tripod, check that its tripod-head mount has a 3/8-inch thread. You can then purchase the TH10 tripod head separately and use it with your existing tripod.
Quickly generate an imaging plan based on your targets and observing conditions, then let the device follow it automatically. If you are unsure what to capture or how to adjust settings, Auto Plan helps you get started with less manual setup and fewer repeated steps.
Yes. Use Telescope Network in the Seestar App to control your S30 Plus remotely.
Once you connect to the remote device, the system automatically uses its location. You can check local observing conditions and the altitude of your target in real time, select a target, and start imaging.
Important Note
[1] Both the telephoto and wide-angle cameras capture at 2K resolution (1440 × 2560) at 1× zoom. Resolution is reduced at 2× and 4× zoom. Live preview streams from both cameras are 1080p.
[2] Milky Way photography requires a dark night sky. The Milky Way is less visible in areas with high light pollution. Actual results depend on local conditions.
[3] S30 Plus does not support wide-angle mosaic stitching. Milky Way panorama stitching and Milky Way arch capture are therefore unavailable.
[4] S30 Plus does not support simultaneous capture with the telephoto and wide-angle cameras.
[5] An NFC-enabled phone is required. NFC reading is supported only on certain newer iPhone models; older models are not supported. Android compatibility varies by manufacturer.
Check your phone's compatibility before use. To use NFC, turn on the device, unlock your phone, and enable Wi-Fi, Bluetooth, NFC and GPS on your phone. NFC detection performance varies with the size and position of the phone's NFC antenna.
Locate your phone's NFC detection area before use. If the Wi-Fi name has been changed, the NFC information must be updated using your phone. Otherwise, NFC will not work.
[6] Due to storage chip characteristics and space used by the system, approximately 45 GB is available for use. System updates may affect storage allocation. Actual available capacity may vary.
[7] Battery life was measured in ZWO laboratory tests at 25°C: approximately 6 hours in Stargazing Mode (image enhancement and celestial tracking enabled, anti-dew function off), and approximately 4 hours recording video in Scenery Mode (object tracking off, MP4 format). These figures are for reference only. Frequent operation and keeping a phone continuously connected to the device can affect battery life. Actual battery life may vary.
[8] 60s long exposures are supported only in Equatorial Mode, not in Alt-Azimuth Mode. They require high tracking accuracy. In Equatorial Mode, very precise polar alignment is needed to maintain that accuracy. Inaccurate alignment may reduce imaging efficiency. Actual performance may vary.
[9] A solar filter must be installed when observing the Sun. Never point the telescope's main camera directly at the Sun without a solar filter, as this will damage the device.
[10] Smart Noise Reduction reduces noise and refines the appearance of stars in real astrophotography images. It enhances existing images and does not create AI-generated images. Seestar S30 Plus is a smart telescope. All images it captures are real photographs, with no AI-generated content.
[11] A Wi-Fi transmission range of 20m was measured in ZWO laboratory tests in an open outdoor area without interference. This figure is for reference only. Actual range may vary with the environment and conditions of use.
[12] The slew rate multiplier is the ratio of the device's rotation speed to the sidereal rate. 1× is the standard sidereal rate(approximately 15″/s, or 0.00418°/s), used for synchronized tracking in astrophotography. 1440× is the maximum GOTO slew rate (approximately 6°/s), used to move quickly to a target celestial object. The device automatically adjusts the rate from 1× to 1440× according to the operating mode and use case.
[13] If the weather changes unexpectedly during a planned capture session, such as overcast skies, rain or strong winds, the task cannot be completed and the device will not shut down automatically. Check the expected weather conditions for the night before setting up a plan.
