Product Introduction

New DSO Camera with High Sensitivity

• 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 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.

DSO & Planetary Imaging

• 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 40ke-, 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.

No 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!

Notice for Use

• Before using the camera, please read this manual carefully.
• 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.
• Note that the camera can only be used and stored under the following conditions. Usage out of the environment limits might lead to damage to the camera.

• Please do not use corrosive solutions to clean the camera to avoid corroding the oxide layer on the surface and damaging the camera.
• Meanwhile, please do not keep the camera exposed to the sun for a long time to avoid discoloration of the oxide layer on the camera surface.

Camera Specifications

Quantum Efficiency & Read Noise 

• Quantum Efficiency
  • According to our test results, the QE peak value of ASI585MC Pro is 91%.

Read Noise

• The camera has a built-in HCG mode, which can effectively reduce read noise at high gain and keep the dynamic range at the same level as it does at low gain.
• At gain 252 and above, the HCG mode is automatically turned on; the dynamic range is close to 11 stops; the read noise can be lower than 0.9e.

Analog to Digital Converter (ADC)

• ASI585MC Pro records in 12-bit ADC and 10-bit ADC. You can image at a faster frame rate if you use 10-bit ADC (high-speed mode).
• You may also set an ROI if you want even faster frame rates.
• Below are the maximum speeds of ASI585MC Pro running at different USB transmission modes.

High-speed Mode： 10BIT ADC
RAW16| RAW8| RAW8| RAW16| RAW8| RAW8
38402160| 23.7fps| 46.9fps| 46.9fps| 2.61fps| 5.2fps| 5.2fps
19201080| 91.4fps| 91.4fps| 91.4fps| 10.4fps| 20.8fps| 20.8fps

640480| 192.9fps| 192.9fps| 192.9fps| 70.5fps| 141.3fps| 141.3fps
320*240| 347.3fps| 347.3fps| 347.3fps| 283.1fps| 347.3fps| 347.3fps

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℃.

Power Consumption

• All ASI cameras have low power consumption.
• ASI585MC Pro is no exception.
• When it’s at cooling status, the max power consumption is only 2.865W.

High Transmission Speed

• 512M DDR3 buffer: This can ensure a stable data transmission in long exposure conditions, minimizing frame drops and also reducing the requirements for the computer hardware.
• 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.

What’s in the Box?

• The 2m USB 3.0 cable and two 0.5m USB 2.0 cables can meet multiple requirements in different usage scenarios.
• For example, the 2m long cable can be used for guiding a PC. The 0.5m short cables can be used to connect
• ASIAIR to the guide camera or EAF.
• Spacers x4: 0.1mm 1; 0.2mm 2; 0.5mm *1
