  • Player One Uranus-C Pro Color IMX585 Cooled Astrophotography Camera

    The Player One Uranus-C Pro combines a large 1/1.2" Sony IMX585 sensor with deep-sky imaging credentials, offering 8.3MP resolution and a massive 47k e- full well capacity. Its 2.9μm pixels and peak QE of approximately 91% deliver high sensitivity, while the 2-stage TEC cooler achieves a 35°C-40°C delta below ambient for clean, low-noise long exposures. Capable of running at 47 FPS over USB 3.0, this 420g camera bridges the gap between high-speed planetary capture and cooled deep-sky imaging.

    The IMX585 Sensor: 8.3MP Resolution and 47k Full Well

    At the core of the Uranus-C Pro is Sony's STARVIS 2-based IMX585 sensor, a 1/1.2" format chip that provides a generous 12.85mm diagonal. With a resolution of 3856x2180 and 2.9μm pixels, it's well-suited for a wide range of focal lengths. The standout feature is its 47,000e- full well capacity, allowing you to capture extended detail in bright targets like the Orion Nebula (M42) without saturating the stars in the core.

    This deep well, combined with a low read noise floor of just 0.7e at high gain, yields exceptional dynamic range. The sensor's back-illuminated architecture ensures a peak Quantum Efficiency of ~91%, making it highly effective at capturing faint photons from distant galaxies and emission nebulae during long exposures.

    47 FPS Full-Frame Capture with a 512MB Buffer

    The Uranus-C Pro is not just for deep-sky imaging; it excels at high-speed solar, lunar, and planetary work. It can deliver full-resolution 3840x2160 frames at 47 FPS in 10-bit mode. When using a smaller region of interest, frame rates increase dramatically, reaching up to 418 FPS at 640x480, ideal for freezing atmospheric turbulence during planetary observation.

    To ensure stable data transfer without dropped frames, the camera incorporates a 512MB DDR3 buffer. This cache handles the high data throughput, preventing bottlenecks and reducing CPU load on your computer. This makes high-frame-rate capture reliable even on less powerful field laptops.

    2-Stage TEC Cooling: 40°C Delta-T and Zero Amp Glow

    For serious deep-sky imaging, thermal noise is the primary challenge. The Uranus-C Pro integrates a 2-stage thermoelectric cooler capable of reducing the sensor temperature by 35°C to 40°C below ambient. This aggressive cooling dramatically reduces dark current, resulting in clean, smooth backgrounds even in multi-minute exposures.

    Critically, the IMX585 sensor exhibits no amplifier glow, a common artifact in many CMOS sensors that can contaminate the corners of an image. This "Non-Amp-Glow" characteristic means your dark frames are truly dark, simplifying calibration and making it easier to pull out the faintest details from your light frames.

    420g Carbon Fiber Body with Advanced Sensor Tilting

    Player One engineered the Uranus-C Pro for both rigidity and minimal weight. The housing uses carbon fiber plates and a CNC-machined aluminum body, keeping the total weight to just 420g. This reduces the load on your focuser and mount, making it easier to achieve and maintain perfect balance.

    To ensure sharp stars across the entire 12.85mm diagonal, the camera includes a sensor tilt plate. This allows you to precisely adjust the sensor's orthogonality to the optical axis, correcting for any tilt in your imaging train. This feature is essential for achieving a perfectly flat field, especially when using fast optical systems like a RASA or HyperStar.

    Uranus-C Pro vs. IMX485 Cameras: A 3.6x Leap in Dynamic Range

    The IMX585 sensor in the Uranus-C Pro represents a significant upgrade over the previous generation IMX485 sensor found in many planetary and EAA cameras.

    • Full Well Capacity: The Uranus-C Pro's 47k e- full well is nearly 3.6 times deeper than the 13k e- of the IMX485. This provides substantially more dynamic range, preventing clipped stars in dense fields or bright nebulae.
    • Frame Rate: Despite its larger file sizes, the Uranus-C Pro is significantly faster, offering 47 FPS at full resolution compared to the typical ~20-25 FPS of an IMX485 camera.
    • Amp Glow: The IMX585 has zero amplifier glow, a notable advantage over the IMX485 which often requires careful calibration to remove glow artifacts from long exposures.

  • What kind of power supply does the Uranus-C Pro need for cooling?

    To use the 2-stage TEC cooling system, you need an external 12V DC power supply with a 5.5x2.1mm center-positive plug, rated for at least 5A. The camera's maximum power consumption is 3A. A power supply is not included with the camera. If you only connect the USB-C cable, the camera will function as an uncooled planetary camera.

    Is the Uranus-C Pro good for imaging the full disk of the Moon or Sun?

    Yes. Its 1/1.2" sensor (11.2mm x 6.3mm) is large enough to capture the entire disk of the Sun or Moon with short focal length refractors (typically those under 400-500mm focal length). The high frame rate of 47 FPS is also excellent for creating sharp, detailed mosaics with larger telescopes. Never image the Sun without a certified solar filter.

    How does the 512MB DDR3 buffer on the Uranus-C Pro help?

    The 512MB DDR3 buffer acts as a temporary high-speed memory cache for image frames. It prevents data loss (dropped frames) during high-speed planetary or solar imaging, especially if your computer's hard drive has slower write speeds. This ensures a smooth and stable data stream from the camera to your PC.

    What is the purpose of the sensor tilt plate on the Uranus-C Pro?

    The sensor tilt plate allows you to make micro-adjustments to the angle of the sensor relative to your telescope's optical path. This is used to correct for any tilt in your focuser or other accessories, ensuring that stars are perfectly round and sharp across the entire field of view, from the center to the corners.

    Can I use the Uranus-C Pro for Electronically-Assisted Astronomy (EAA)?

    Absolutely. The Uranus-C Pro is an excellent camera for EAA. Its high sensitivity from the ~91% QE, low read noise, and lack of amp glow allow for clean, detailed color images with very short exposures. You can stack frames live to see deep-sky objects like the Hercules Cluster (M13) or the Ring Nebula (M57) in near-real-time.

    What is included with the base model of the Uranus-C Pro camera?

    The `whats_in_the_box` for this product is not specified for the base camera package. Player One offers bundles that may include accessories like a filter drawer or filters. Please check the purchase options to see what is included in your selected package.
