ASI585MC adopts Sony IMX585 CMOS sensor. As one of ZWO's latest OSC planetary cameras, it features a large sensor format of 1/1.2", a high resolution of 3840x2160, and a surprisingly amazing characteristic of 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 pixel size is 2.9umx2.9um. In 12-bit mode, it produces 46.9 FPS with super low readout noise!
STARVIS 2
- ASI585MC adopts the latest SONY IMX585 sensor with STARVIS 2 technology. Featuring zero amp glow, lower dark current noise, and 3 times larger full well capacity, this camera is regarded as an upgrade of ASI485MC. It is also more sensitive to red, green and near infrared (NIR) lights compared to ASI485MC, especially in >850nm wavelength range, its light sensitivity is 1.5 times greater than ASI485MC.
USB 3.0 & 256MB DDR3 Memory
- The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3 cache to ensure stable and secure data transmission. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.
Upgraded Model
- The ASI585MC is an upgraded camera to the ASI485MC. Compared with the ASI485MC, it has the characteristics of a larger full well depth and no amp glow.
Large Full Well Depth
- 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.
Camera Curve: Low read noise, high dynamic range
- With ZWO’s upgraded High Conversion Gain (HCG) mode, the ASI585MC achieves an impressive 12 stops of dynamic range—reducing noise and preserving fine detail in both faint and bright areas of your images.
Quantum Efficiency
- After our calculation, the peak quantum efficiency of ASI585MC is 91%.
No Amp Glow
- 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.
Specifications
