ZWO ASI585MC Pro USB3.0 Color Astronomy Camera

Capture stunning, high-resolution images of deep-sky objects with the ASI585MC Pro USB3.0 Color Astronomy Camera from ZWO. Equipped with a 1/1.2" Sony IMX585 color CMOS sensor, the camera achieves 8.3MP resolution with low read noise and no amp glow. The two-stage thermoelectric cooler lowers the temperature to 95° F below ambient, all but eliminating dark current noise for a clean image even with very long exposures. The USB 3.0 port accommodates the high frame rate you'll need for planetary imaging. The ASI585MC Pro requires a separately sold 12V 3-5A power supply, 5.5 x 2.1mm, center-positive.

8.3MP Sony IMX585 Sensor

The 1/1.2" format color sensor boasts a resolution of 3840 x 2160, while the 2.9µ pixels accommodate an impressive full well capacity of 40ke.

No Amp Glow

Using zero-glow amp circuitry, the ASI585MC Pro eliminates amp glow— a weak infrared light source often created by traditional CMOS sensors, sometimes seen in the corners of uncalibrated images. You won't have to worry about it, even during high-gain, long-exposure imaging.

High Conversion Gain Mode

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.

Two-Stage TEC Cooling

Thanks to the two-stage TEC cooling, ASI585MC Pro can lower the CMOS sensor temperature to more than 95° F below ambient temperature, which can greatly reduce dark current generation and sensor noise even during extended exposure times.

USB 3.0 & 2.0 Connectivity

The camera features a USB-B 3.0 port that provides 5GFB bandwidth for data transfer, allowing the camera to run at 47 fps at full resolution. Two USB-A 2.0 ports allow for connection to an electronic filter wheel, an electronic autofocuser, or a guide camera.

Adapters for Connecting to Your Telescope

The ASI585MC Pro comes with an assortment of connectors: one M42-M48 adapter, one M42-M48 16.5mm extender, one M42-1.25" adapter, one M42 21mm extender, and one 1.25" nosepiece, along with four extenders.
