Product Description
ASI585MC 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, center 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.
ASI585MC Pro
One Camera for All
The STARVIS 2 technology brings ASI585MC 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, ASI585MC 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 unbinned 2.9μm pixels, ASI585MC Pro has a full well capacity of 47ke-, nearly 4 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
ASI585MC 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
ASI585MC 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℃.
Camera Performance
Low read noise, High dynamic range
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 0.9e.
QE (Quantum efficiency)
Based on our testing results, the QE peak value of ASI585MC Pro is 91%.

Customer Reviews
Great camera it’s two in one! Great for planetary and also great for deep sky imaging, I would recommend this camera if your looking for something versatile!
It is well worth the money. A great value. However, a warning to newbies, it is the processing of the images that will be your greatest challenge. If this will be your first one shot colour camera, make sure you know how you will be processing the images before you buy. This will ensure a good experience.
I'm a beginner to intermediate astro enthusiast looking to improve from using a DSLR to a dedicated astro camera. The attached image was taken using my Askar 103APO with 0.8x reducer and Optolong L-Pro filter on a Celestron AVX mount. The 4 hour integrated 2 min subs (Bortle 7.8 sky) image of NGC 6888 was stacked and processed using Siril, and post processed using Affinity Photo. This camera hits the right price point for entry level astro imaging with enough resolution for a reach using just a 4 inch telescope. Obviously the sensor size does not cover the full telescope's image field of view but the positive consequence is that I have less vignetting to mitigate. I am overall happy with the performance and image quality validating the CCD compatibility as predicted from the astronomy.tools website. I highly recommend this camera for the beginner to intermediate astro enthusiast looking to upgrade from a DSLR to a dedicated astro camera in their acquisition path.
