Astronomical OSC camera with large full well capacity

ASI585MC adopts Sony's IMX585 CMOS sensor. As one of the ZWO's latest OSC planetary cameras, it features a large sensor format of 1/1.2", a high resolution of 3840x2160 (and a pixel size of 2.9μm), and zero amp glow! In 12-bit mode, it produces 46.9 FPS with super low readout noise!

8.29MP Sensor

ASi585MC has the same pixel size as the ASI462 at 2.9μm, but its larger sensor delivers four times the total number of pixels, at 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. 


ASI585MC adopts the latest Sony IMX585 sensor with STARVIS 2 technology.

Featuring zero amp glow, lower dark current noise, and three 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) light compared to ASI485MC—especially in the >850nm wavelength range, its light sensitivity is 1.5 times greater than ASI485MC.

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 excellently, capturing very clear images of celestial objects.

Camera Curve
(Low read noise, high dyamic range)

The camera has a built-in High Conversion Gain (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 dynamic range reaches a level close to 12 bit. 

The readout noise is as low as 1.5e.

No Amp Glow

ASI585MC exhibits zero amp glow, no matter how long the exposure is and how high the gain value. It's implemented at the hardware level, so it doesn't require software control.
