Pre-order yours now!

The New Seestar S50 Pro Smart Telescope integrates a 50mm APO telescope, 4K camera, and motorized mount into one portable setup. Designed for night-sky astrophotography and daytime telephoto viewing, it delivers automated, high-resolution imaging in three simple steps.

  • 50mm APO Optics & 4K Sensor: 4-element Extra-low Dispersion (ED) lens with a 1/1.2" sensor captures sharp, color-accurate deep-sky details with nearly 3x the light-gathering area of 30mm models.

  • 4K Dual-Lens & 8K Mosaic: Dual telephoto and wide-angle cameras combine for deep-space and starfield shots, with automated stitching for up to 8K panoramas.

  • Smart GOTO: Integrated AI assistant and target database automatically locate, frame, and track celestial objects.

  • Triple Filter System: Built-in light pollution, dark frame, and IR-cut filters eliminate city glow and sensor noise for clean exposures.

  • Equatorial Mode & 9-Hour Battery: Precision drive system enables long-exposure tracking, backed by a 10,000 mAh battery for all-night imaging.

  • Advanced & Remote Access: Features plan mode automation, global remote control, and ASCOM Alpaca support for software like N.I.N.A.

Professional-Grade Imaging
All-in-One. Ready for more.

Traditional astrophotography often requires multiple devices—such as a telescope, equatorial mount, and camera—along with complex wiring and setup.

Seestar integrates its core imaging system into one compact device for easy carrying and fast setup. Whether you’re on a family trip or embarking on your next outdoor creative adventure, capture the beauty of the universe whenever inspiration strikes.

50 mm Large Aperture
Sharper Detail. Greater Light-Gathering Power.

With nearly three times the light-gathering area of a 30 mm aperture, the 50 mm aperture delivers faster light collection and greater optical resolving power. Paired with a 4K 1/1.2-inch large-format sensor, it reveals rich detail—from faint structures in deep-sky objects to the intricate textures of the Sun and Moon.
 

Greater light-gathering power with Seestar s50 pro's larger 50mm aperture!

4-Element Apochromatic Lens

Engineered to minimize chromatic aberration, the 4-element apochromatic lens (with an Extra-low Dispersion glass) delivers rounder, sharper stars and clean, neutral blacks.
The result is a night sky rendered with clarity and balance — true to what the eye expects and the universe deserves.

Triple Filter System

  • Astronomical light pollution filter reduces interference from moonlight and urban light pollution.
  • Dark frame filter subtracts noise from long exposures.
  • IR-cut filter blocks infrared interference for cleaner astrophotography.

4K Dual-Lens - Ultra-Clear Imaging to See Deeper and Capture Wider

Telephoto and wide-angle cameras work together, both supporting 4K UHD resolution.
The telephoto camera features a 1/1.2" large sensor for clearer deep-sky object details.
The wide-angle camera records a broader starfield, keeping the whole scene in frame.
The dual-camera system balances deep-sky capture with wide-field astro shooting.

4K telephoto and wide-angle lenses allow S50 Pro to focus on deep-sky detail and wide-filed astrophotography.
