The ASI585MC/MM Pro is the latest ZWO deep sky camera featuring a 4K SONY CMOS sensor with a 1/1.2? format and 2.9?m pixels. It offers high sensitivity and a large resolution of 3840×2160 (8.29MP).
With high-speed transmission, the camera achieves up to 47fps in high-speed mode with low read noise at full resolution. It is particularly effective in near-infrared wavelengths, making it an excellent entry-level DSO camera with great cost-effectiveness.
High-Sensitivity Sony Sensor – Equipped with a Sony IMX585 sensor for exceptional low-light performance.
High Quantum Efficiency (QE) – Maximizes the amount of light captured for superior image quality.
Low Read Noise & High Dynamic Range – Ensures clean and detailed images.
High Frame Rate & USB 3.0 Connectivity – Enables fast data transfer and high-speed imaging.
Efficient Cooling System – Reduces thermal noise, allowing for long-exposure astrophotography.
16-Bit ADC (Analog-to-Digital Converter) – Provides a broader dynamic range and smooth transitions in color depth.
Compact & Lightweight Design – Easy to mount on various telescope setups.
Multi-Compatibility – Works seamlessly with software like SharpCap, FireCapture, NINA, and ASCOM drivers.
State-of-the-Art Sony IMX585 Sensor for ultra-clear astrophotography.
High Sensitivity & Low Noise for superior imaging performance.
Advanced TEC Cooling for extended deep-sky exposures.
Fast USB 3.0 Data Transfer for high-frame-rate planetary imaging.
Compatible with Leading Astrophotography Software for seamless integration.
Perfect for Both Beginners & Professionals in astrophotography.
External power is required for all ASI-cooled cameras.
Recommended power supply: 12V @ 3A~5A DC adapter (D5.5×2.1mm, center pole positive) or lithium battery (11-14V).
Using a power supply outside this voltage range may cause irreparable damage to the camera.
The STARVIS 2 technology brings ASI585 Series 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.
The back-illuminated structure improves the camera’s full well capacity. Even with unbinned 2.9?m pixels, ASI585 Series 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.
ASI585 Series 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.
The STARVIS 2 technology gives the ASI585 Series superior imaging capabilities compared to other cooled cameras.
Ideal for:
Deep-sky photography (DSO)
Solar, lunar, and planetary photography
High frame rate ensures smooth and detailed captures.3
The back-illuminated structure enhances light collection efficiency.
Full well capacity: 40ke- (nearly 3× that of the previous IMX485 sensor).
Helps prevent overexposure in bright areas and improves signal-to-noise ratio.
Note: This feature is implemented directly at the hardware level, it does not require software control.
ASI585 Series 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: Provides 5Gb bandwidth to allow ASI585 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.
Thanks to the two-stage TEC cooling, ASI585 Series 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 ASI585 Series at the temperature from -20? to 30?.
The camera 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.
Based on our testing results, the QE peak value of ASI585 is 91%.
The ASI585 Series produces dark frames with zero amp glow.
No matter the exposure time or gain settings, you get clean and smooth astrophotography results.
Note: This feature is hardware-implemented and does not require software control.
