Seestar S30 Pro Smart Telescope

A 1.65 kg All-in-One Smart Telescope

The Seestar S30 Pro is engineered for astronomers who prioritize portability and ease of use without sacrificing image quality. It combines a telescope, autofocus, camera, alt-azimuth mount, filter wheel, and controller into a highly integrated unit that weighs just 1650 g. This all-in-one design eliminates the complexity of traditional astrophotography setups, allowing you to go from unboxing to imaging in minutes.

Designed for both beginners and traveling astrophotographers, its primary function is to make capturing the universe effortless. Simply power it on, connect to the app, and select a target. The Seestar S30 Pro handles the rest, from automatic GoTo slewing and tracking to live image stacking and processing, delivering impressive cosmic images directly to your device.

30mm f/5.3 Apochromatic Telephoto Optics

At the heart of the Seestar S30 Pro is a 4-element apochromatic lens system featuring Extra-low Dispersion (ED) glass. This professional-grade optical design minimizes chromatic aberration, resulting in sharp, high-contrast images with clean black backgrounds and stars that appear as tight, round points of light. The telephoto lens has a 30mm aperture and a 160mm focal length, yielding a focal ratio of f/5.3.

The telephoto camera's 4.6° field of view suits wide starfields and large deep-sky objects like the Andromeda Galaxy (M31) or the Orion Nebula (M42). A second wide-angle lens with a 3.4mm aperture and f/1.75 focal ratio provides a massive 63° field of view, for capturing entire constellations or creating time-lapses of the Milky Way.

Dual 8.3MP Sony IMX585 & IMX586 Sensors

The S30 Pro employs a dual-camera system to provide both detailed telephoto views and expansive wide-field context. The main telephoto camera uses a high-sensitivity Sony IMX585 sensor, while the wide-angle camera is built around a Sony IMX586. Both sensors capture 4K Ultra HD images with a resolution of 3840 x 2160, or 8.3 megapixels.

The telephoto sensor delivers a 4.6° field of view, ideal for framing galaxies, nebulae, and star clusters. The wide-angle sensor's 63° field is used for the Milky Way, star trails and other vast celestial scenes. The S30 Pro also offers intelligent constellation recognition and automated mosaic stitching, creating ultra-high-resolution panoramas of up to 8K.

Triple Built-in Filters and a Magnetic Solar Filter

To enhance imaging under various conditions, the Seestar S30 Pro includes a built-in three-filter system on an internal filter wheel. It adapts your captures for optimal clarity and contrast without requiring external accessories.

• UV/IR Cut Filter: Blocks unwanted infrared and ultraviolet light, preserving clarity and true color.
• Light Pollution Filter: A dual-bandpass filter targeting OIII (30nm) and Hα (20nm) emission lines. It reduces the effects of moonlight and urban glow, revealing emission nebulae with striking contrast.
• Dark Field Filter: An internal filter used to automate the dark frame calibration process, effectively reducing long-exposure sensor noise for cleaner deep-sky images.
• Magnetic Solar Filter: An external magnetic solar filter is included for observing the Sun. Warning: A solar filter must be installed when observing the Sun. Never allow the main camera to observe the Sun directly, as this may cause permanent damage to the device.

4K Deep-Sky, Planetary, Scenery, and Time-Lapse

The S30 Pro is equipped with four primary imaging modes, enabling you to capture a wide variety of subjects in 4K Ultra HD. The app simplifies complex astrophotography techniques into single-tap operations, from deep-sky live stacking to creating star trail videos.

In Stargazing mode, the Seestar automatically points to and tracks deep-sky objects, planets, the Sun, or the Moon, stacking images in real-time to reveal faint details. Scenery mode turns the S30 Pro into a powerful ultra-telephoto lens for daytime birdwatching or landscape photography. Finally, dedicated modes for creating Milky Way mosaics, star trail photos, and time-lapse videos unlock creative possibilities for capturing the dynamic motion of the sky.

Alt-Azimuth Mount with Equatorial Mode Support

Out of the box, the Seestar S30 Pro operates on a simple and intuitive alt-azimuth mount. This system is perfect for quick setup and casual observation, automatically tracking celestial objects as they move across the sky. For beginners, this is the easiest way to start capturing stunning images immediately.

For more advanced astrophotography, the S30 Pro also supports an Equatorial (EQ) Mode. When aligned with the celestial pole (this requires additional accessories; the Seestar TH10 Fluid Tripod Head with the TC20 Carbon Fiber Tripod is recommended for the S30 Pro), this mode tracks the sky in a single arc, countering Earth's rotation more accurately. This eliminates field rotation, enabling longer individual exposures for capturing fainter deep-sky details with sharper stars.

Seestar App with Wi-Fi and ASCOM Alpaca Support

The entire Seestar experience is driven by the Seestar app. It connects to the telescope via Wi-Fi or Bluetooth and provides a user-friendly interface for controlling all functions, from selecting targets among 80,000+ deep-sky objects and 600,000+ stars to managing image processing and storage. The app also features intelligent constellation recognition and one-tap post-processing.

For advanced users who want to integrate the S30 Pro into a larger workflow, the system supports the open ASCOM Alpaca protocol. This enables compatibility with a wide range of third-party astrophotography software, such as N.I.N.A., allowing for fully customized and automated imaging sequences from a PC.

6000mAh Battery and 128GB Onboard Storage

Designed to be a completely field-ready instrument, the Seestar S30 Pro is powered by an internal 6000mAh rechargeable battery. This provides approximately 6 hours of operation in stargazing mode (ZWO laboratory test data). The battery is charged via a standard USB Type-C port with a 5V 3A power input.

All images and videos are saved directly to the device's 128GB of internal eMMC storage. This generous capacity lets you keep capturing without stopping to manage files or clear space. Files can be transferred to your phone or computer via Wi-Fi or the USB Type-C connection.

A 1650g Go-Anywhere Astrophotography System

The Seestar S30 Pro's greatest strength is its extreme portability. Weighing only 1650 g (1.65 kg), it is light enough to pack in a backpack and take anywhere. The included carrying case and tripod ensure the entire system is protected and ready for travel, whether you're heading to a local park or flying to a dark-sky destination.

This compact, lightweight design makes astrophotography accessible in situations where a traditional setup would be impractical. Just power it on and start exploring.

Seestar S30 Pro vs. Seestar S50 Pro: Aperture and Portability

The Seestar S30 Pro and S50 Pro are both powerful smart telescopes, but they are optimized for different priorities. The choice between them comes down to a trade-off between light-gathering power and portability.

• Seestar S50 Pro Advantage: With its larger 50mm aperture, the S50 Pro gathers nearly three times more light than the S30 Pro's 30mm objective. The S50 Pro is built for deep-sky imaging, with a larger aperture, a more capable tracking system and richer image detail.
• Seestar S30 Pro Advantage: The S30 Pro is significantly lighter and more compact, weighing only 1.65 kg compared to the S50 Pro's 2.8 kg. If your primary need is a telescope for travel, hiking, or quick backyard sessions, the S30 Pro's portability is its defining feature.

The S30 Pro is a portable all-rounder for a wide range of shooting scenarios. If portability and versatile everyday shooting are your priorities, the S30 Pro fits; if you want to capture fainter deep-sky objects and greater imaging detail, the S50 Pro is the step up.

Your First Night with the Seestar S30 Pro

Using the Seestar S30 Pro is designed to be incredibly simple, even with zero prior experience. In just a few steps, you can be capturing your first deep-sky object.

1. Set Up and Power On: Place the included tripod on level ground, mount the Seestar, and press the power button.
2. Connect with the App: Open the Seestar app on your smartphone or tablet and connect to the telescope over Wi-Fi or Bluetooth.
3. Select a Target and Go: Browse the celestial database for a target like the Moon, Jupiter, or a bright nebula. Tap the "GoTo" button. The Seestar will automatically slew to the object, center it, and begin tracking. It will then start live-stacking images, with the view on your screen getting progressively clearer and more detailed over the next few minutes.
