Additionally, the ZWO ASI 585MC Pro includes a USB 2.0 hub for connecting accessories such as an electronic focuser or filter wheel, helping to streamline your imaging setup. The integration of these features makes the ZWO ASI 585MC Pro a user-friendly and versatile camera for a wide range of astrophotography applications.

ZWO ASI 585MC Pro Advanced Cooling System for Long-Exposure Imaging

The ASI 585MC Pro is equipped with a two-stage TEC (thermoelectric cooling) system, which reduces the sensor temperature to up to 35°C below ambient. This significantly reduces thermal noise during long-exposure imaging, making it ideal for deep-sky astrophotography. The cooling system is designed for efficiency and reliability, ensuring stable performance even during extended imaging sessions under varying conditions.

ZWO ASI 585MC Pro Compact and Durable Design

Built with ZWO's signature attention to quality and detail, the ASI 585MC Pro features a compact and durable aluminium housing.

ZWO ASI 585MC Pro  is a new ZWO deep sky camera based on the 4k SONY CMOS sensor with a 1/1.2″ format and 2.9μm pixels. It has a super high sensitivity and a large resolution of 3840*2160 (8.29MP in total). It also features high transmission speeds – In high-speed mode, the fast frame rate can reach 47fps at full resolution! Being an entry-level DSO camera, it offers great advantages of high cost-effectiveness.

Note:

External power supplies are needed for all ASl-cooled cameras. We recommend you use a 12V@3A~5A DC adapter (D5.5×2.1mm, centre pole positive) or a lithium battery with 11-14V to power the camera. You can also use ASIAlR to power the cameras. Be aware that using a power supply out of this voltage range will probably lead to irreparable damage to the camera.

ZWO ASI 585MC Pro 

One Camera for All

The STARVIS 2 technology brings ZWO ASI 585MC Pro  more advanced imaging performance compared to other cooled cameras. Its high frame rate makes it not only suitable for DSO photography but also solar/lunar/planetary photography.

STARVIS 2

STARVIS 2 was developed by SONY and evolved from STARVIS. It is the latest technology with a wider dynamic range and super-high sensitivity beyond the human eye. Benefiting from it, ZWO ASI 585MC Pro ’s sensitivity and signal-to-noise ratio is greatly improved.

Large Full Well Capacity

The back-illuminated structure improves the camera’s full well capacity. Even with un binned 2.9μm pixels, ZWO ASI 585MC Pro  has a full well capacity of 40ke-, nearly 3 times that of the last-generation sensor IMX485. A larger full well capacity gets the camera higher efficiency in collecting light, can effectively restrain the highlight area from being overexposed, and also can improve the signal-to-noise ratio.

Zero Amp Glow

ZWO ASI 585MC Pro  exhibits extremely clean dark frames with zero amp glow! No matter how long the exposure and how high the gain value is, you can easily get clean and smooth astro images!

Note: This feature is implemented directly at the hardware level, it does not require software control.

512MB DDR3

ZWO ASI 585MC Pro  uses a USB 3.0 interface, along with the built-in 512MB DDR3 cache, ensuring high-speed, smooth, and stable data transmission.

USB 3.0 Port & USB 2.0 HUB

USB 3.0 Port: Provides 5Gb bandwidth to allow ASI585MC Pro to run at 47fps at 8.29MP full resolution (10bit, high-speed mode).
USB 2.0 HUB: Can be used to connect various kinds of USB devices such as EFW, guide camera, and EAF.

Two-stage TEC Cooling

Thanks to the two-stage TEC cooling, ASI585MC Pro can lower the CMOS sensor temperature to more than 35 degrees Celsius below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.

*The Delta T 35℃ is tested at 30℃ ambient temperature. It might get down when the cooling system is working for a long time. Also, as the ambient temperature falls, the Delta T would decrease.

Below is the dark current curve of ASI585MC Pro at the temperature from -20℃ to 30℃.

ZWO ASI 585MC Pro Camera Performance

Low read noise, High dynamic range

The ZWO ASI 585MC Pro has a built-in HCG mode, which can effectively reduce read noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain.

When the gain reaches 252, the HCG mode will be automatically turned on and the dynamic range reaches a level close to 11bit. The read noise in this case can be as low as 0.7e.
