Astronomical Camera with Large Full Well Capacity
The ASI585MM adopts Sony IMX585 CMOS sensor. As one of ZWO's latest 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 2.9µm x 2.9µm. In 12-bit mode, it produces 46.9 FPS with super low readout noise!
8.29MP Sensor
The ASI585MM has the same pixel size of the ASI462MC at 2.9µm, but its resolution is 4 times that of ASI462MC, which is a total of 8.29 megapixels. The sensor size is 11.13x6.26mm, and the diagonal length is 12.84mm.
The 1/1.2" large sensor format makes it very suitable for solar and lunar imaging. It can also be used as an all-sky camera or live camera to observe and monitor cloud cover, rain, meteors and other weather conditions.
STARVIS 2
The ASI585MM 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. It is also more sensitive to red, green and near infrared (NIR) lights especially in >850nm wavelength range.
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 transmis-sion. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.
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 ASI585MM 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
The peak quantum efficiency of the ASI585MM is 91%.
No Amp Glow
The ASI585MM 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.
