The ZWO ASI585MC Pro is a deep-sky camera featuring a 4K Sony CMOS sensor with 2.9μm pixels and high sensitivity. With 47fps at full resolution, zero amp glow, and advanced cooling, it's perfect for both deep-sky and planetary imaging, offering high performance at an affordable price.

The ZWO ASI585MC Pro is the latest addition to ZWO's line of deep-sky cameras. It's built around a 4K Sony CMOS sensor with a 1/1.2″ format and 2.9μm pixels, delivering a resolution of 3840x2160 (8.29MP). This camera offers high sensitivity and a fast frame rate, reaching 47 frames per second at full resolution.

ZWO ASI585MC Pro, deep-sky camera features

  • High Sensitivity: The ASI585MC Pro uses STARVIS 2 technology, enhancing its sensitivity and dynamic range. This allows for better performance in low-light conditions.
  • High Frame Rate: Capable of 47fps at full resolution, making it ideal for planetary imaging and live stacking.
  • Large Full Well Capacity: With a full well capacity of 40ke-, it effectively collects light, reducing the chance of overexposure and improving the signal-to-noise ratio.
  • Zero Amp Glow: Ensures clean and smooth images, even with long exposures and high gain.
  • Data Transmission: Features a USB 3.0 interface and 512MB DDR3 cache for stable and high-speed data transfer. Includes a USB 2.0 hub for connecting additional devices.
  • Two-Stage TEC Cooling: Can cool the sensor to 35 degrees Celsius below ambient temperature, reducing noise during long exposures.

ZWO ASI585MC Pro review by Trevor Jones

Trevor Jones delves into the ZWO ASI585MC Pro, a cooled astronomy camera celebrated for its high-quality images and affordability. Despite its smaller sensor and 12-bit ADC, which might limit the field of view and dynamic range compared to DSLRs, Jones highlights the camera's high sensitivity and ability to capture 50 frames per second, making it ideal for planetary imaging and live stacking. He shares his initial experiences with the camera, capturing images of the Sharpless 112 nebula and the Crescent nebula.

Jones acknowledges some challenges, such as noticeable gradients and potential calibration issues, especially when shooting during a full moon and in city lights. However, he expresses excitement about the camera's potential for deep-sky astrophotography. He plans to use further processing tools to enhance image details.

When discussing the Crescent nebula, Jones praises the camera's performance but notes some odd artifacts and brightening events in the subframes. Despite these anomalies, he achieves a great image and encourages other users to share their experiences with the camera.

Overall, Jones believes the ZWO ASI585MC Pro is a promising option for astrophotographers seeking an affordable and dedicated astronomy camera. Watch the full video below.
