Uranus-M Pro (IMX585) Monochrome Cooled Camera.
The Uranus-M Pro (IMX585) camera, developed by Player One Astronomy, is a state-of-the-art monochrome cooled camera launching in 2025. It features Sony's IMX585 1/1.2” format mono sensor, designed to deliver high-performance imaging with exceptional clarity and sensitivity. With a 2.9μm pixel size, a full well capacity of 47Ke, and a total resolution of 8.3MP (3856x2180), the 12.85mm diagonal sensor is well-suited for deep-sky, solar, lunar, and planetary imaging.
STARVIS2 Technology
Built on Sony’s STARVIS2 back-illuminated pixel technology, the Uranus-M Pro provides enhanced low-light performance and improved quantum efficiency, making it ideal for astrophotography.
Key Features
Cutting-Edge Design
The Uranus-M Pro follows the sleek Ares cooled series design, featuring a lightweight carbon fibre body, a stylish red-and-black colour scheme, and an integrated sensor tilter plate along with an anti-dew PCB board. This ensures a lightweight yet highly functional camera.
Dual Sensor Tilt Plates
-
Front 3P Tilt Plate (Default): Ideal for general astrophotography, ensuring optimal sensor alignment.
-
Rear 4P Tilt Plate (Optional): Designed for use with filter wheels, filter drawers, and OAGs, particularly beneficial for RASA users.
-
Built-in high-density sponge shading pad eliminates light leakage.
Optimized for Lightweight and Portability
With a carbon fibre housing and an optimized structure, the 420g camera is among the lightest cooled cameras available.
Advanced Cooling System
Equipped with a dual-stage TEC cooling system, the Uranus-M Pro achieves a Delta-T of 35–40°C, effectively reducing thermal noise for long-exposure astrophotography.
Anti-Dew Heater
A built-in anti-dew heater prevents condensation on the sensor window, ensuring clear imaging even in humid conditions.
High Performance
-
Full Well Capacity: 47Ke, nearly 3.6 times larger than the previous generation IMX485 (13Ke).
-
Frame Rate: Supports 47 FPS in RAW8 mode, significantly faster than its predecessors.
-
Non-Amp-Glow Technology: Produces completely dark frames, reducing unwanted noise for high-quality imaging.
Ideal for Various Applications
-
Deep-Sky Imaging: Excellent sensitivity for capturing faint nebulae and galaxies.
-
Solar & Lunar Imaging: The 1/1.2” sensor captures the full disk of the Sun and Moon with short focal-length telescopes.
-
Planetary Imaging: High frame rate enables detailed captures of planets like Jupiter and Saturn.
-
Mosaic Imaging: Large sensor size enhances efficiency in assembling wide-field mosaics.
512MB DDR3 Cache for Stability
A 512MB DDR3 cache ensures stable data transmission, preventing frame drops and significantly reducing readout noise. This also allows smooth operation even on USB 2.0 ports.
USB Type-C and Power Management
-
Dual Type-C Data Ports for seamless connectivity.
-
12V DC (5.5×2.1mm) Power Port to power the TEC cooling system.
-
Can function as an uncooled camera if TEC power is not connected.
Customizable Cooling & Anti-Dew Settings
-
Adjustable cooling fan speed and dew heater power settings in the ASCOM driver.
-
Standard Delta-T: 35-40°C with 100% fan speed and 1% dew heater power.
-
Recommended Delta-T settings: 30-35°C, 50-70% fan speed, 10% dew heater power.
Built-in Protection Mechanisms
The Uranus-M Pro features overvoltage and overcurrent protection, ensuring safety and reliability in extended imaging sessions.
Low Readout Noise & High Sensitivity
-
HCG Mode activates at Gain 210, maintaining a balance between dynamic range and noise reduction.
-
Readout Noise: Independently tested, can be analysed using Sharpcap 4 Sensor Analysis.
Exceptional Dark Current Performance
-
0.0004 e/s/pix at -20°C.
-
0.005 e/s/pix at 0°C.
-
Exhibits a nearly linear dark current response curve, ensuring stable performance.
Relative QE Curve
The quantum efficiency curve, provided by Sony Co., Ltd., highlights the high photon-to-electron conversion efficiency, maximizing sensitivity for astrophotography.
Mechanical Drawing & Back Focus Solutions
The camera supports a variety of 55mm back focus length (BFL) configurations, making it compatible with multiple optical setups.
