ZWO ASI585MC Color
8.29MP Sensor
ASI585MC has the same pixel size of the ASI462MC at 2.9um, 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
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 & 256M 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
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 252, the HCG mode is automatically turned on and the daynamic range reachs a level close to 12bit. The readout noise is as low as 1.5e.
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 re quire software control.
