ZWO ASI585MC Pro Cooled Color Astronomy Camera # ASI585MC-P

About this item 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. 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. 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. 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: 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. 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℃. 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. Based on our testing results, the QE peak value of ASI585MC Pro is 91%.
