Player One Uranus-C IMX585 Color Planetary Camera

Sony IMX585 STARVIS 2: A 1/1.2" Sensor with 8.3MP

At the core of the Uranus-C is the Sony IMX585, a large 1/1.2" format color sensor with a 12.85mm diagonal. This large sensor size, combined with an 8.3 MP resolution of 3856x2180, makes capturing the entire lunar disc or creating large planetary mosaics significantly more efficient. The back-illuminated STARVIS 2 architecture and 2.9μm pixels achieve a peak Quantum Efficiency of approximately 91%, ensuring that faint signals from planetary cloud bands or deep-sky targets are registered effectively.

Noise Control: A 47k e- Full Well with Zero Amp Glow

The Uranus-C is engineered for exceptionally clean images, even in demanding EAA (Electronically Assisted Astronomy) and lucky imaging applications. Its standout feature is a complete absence of amplifier glow, providing a uniformly dark background that simplifies processing. This is complemented by a deep 47,000 e- full well capacity and read noise as low as 0.7 electrons, delivering a high dynamic range to capture both the bright core of Jupiter and the subtle detail in its surrounding moons in a single exposure.

47 FPS Capture with Onboard DDR3 Cache

To ensure stable, high-speed video capture, the Uranus-C integrates a DDR3 cache. This buffer prevents frame dropping during planetary imaging sessions by securing data transmission before it's written to your computer. The camera can maintain 47 FPS at its full 8.3 MP resolution over USB 3.0, and can reach up to 418 FPS at reduced resolutions like 640x480, allowing you to freeze moments of excellent seeing. The cache also reduces the demand on the host computer, ensuring reliable operation even when connected to a USB 2.0 port.

Passive Cooling System and 12.5mm Back Focus

The Uranus-C features a Passive Cooling System (PCS) that uses the camera's metal housing to dissipate heat from the sensor, maintaining thermal stability during long imaging sessions. The camera body has a 66mm diameter, weighs only 160g, and provides a standard 12.5mm back focal length. It connects to your telescope using either the included 1.25" nosepiece or its native M42x0.75 threads, offering flexible integration with filter wheels and other accessories.

Player One Uranus-C vs. ZWO ASI585MC: Key Differentiators

While both cameras use the excellent Sony IMX585 sensor, they differ in design philosophy and features. The ZWO ASI585MC is a well-established camera with a large user base and offers dual 6.5mm/17.5mm back focus options for greater hardware flexibility.

The Player One Uranus-C, however, distinguishes itself with specific anti-noise technologies that directly impact image quality.

• Zero Amp Glow: Player One guarantees a completely amp-glow-free sensor, which is a significant advantage for EAA and lucky imaging, resulting in cleaner, easier-to-process backgrounds.
• DPS Technology: The camera features Dead Pixel Suppression (DPS), which analyzes and corrects for fixed abnormal pixels in-camera, reducing post-processing work.
• DDR3 Cache: While both cameras have a buffer, Player One was the first to implement it across their planetary line, ensuring robust data transfer without dropped frames.
