The ZWO ASI585MC camera adopts the Sony IMX585 CMOS sensor with STARVIS 2 technology. As one of ZWO’s latest OSC planetary cameras, it features a large sensor format of 1/1.2″, a high resolution of 3840×2160, and zero amp glow. The pixel size is 2.9umx2.9um. In 12-bit mode, it produces 46.9 FPS with super low readout noise.
The ZWO ASI585MC camera features zero amp glow, lower dark current noise, and 3 times larger full well capacity than the ZWO ASI485MC. It is also more sensitive to red, green and near infrared (NIR) lights compared to the ASI485MC, especially in >850nm wavelength range and its light sensitivity is 1.5 times greater.
Thanks to the back-illuminated sensor structure and advanced pixel technology, the camera has very low readout noise and a large full well depth. Especially in low light conditions, the camera performs excellent, capturing very clear images of celestial objects.
The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain and allow the camera to maintain the same high dynamic range as it does at low gain. When the gain is 150, the HCG mode is automatically turned on and the dynamic range reaches a level close to 12bit. The readout noise is as low as 0.8e. The peak Quantum Efficiency (QE) of the ZWO ASI585MC camera is 91%.
The ZWO ASI585MC exhibits zero amp glow, no matter how long the exposure and how high the gain value. Since it is implemented directly at the hardware level, it does not require software control.
