Capture stunning, high-resolution deep sky object and planetary images with the ASI585MM-P Pro Cooled Monochrome Astronomy Camera from ZWO. Equipped with a Sony IMX585 CMOS sensor, the camera achieves 8.3MP resolution with low read noise and no amp glow. It transmits data to your computer quickly, thanks to the USB 3.0 interface and DDR3 512MB cache, with a frame rate as high as 47 fps. The two-stage thermoelectric cooler lowers the sensor temperature by 95°F below ambient, dramatically reducing dark current noise for a clean image even with very long exposures. Cooling also allows you to match your calibration frames to your imaging for optimal signal-to-noise ratio. The camera's 38.7ke full well capacity allows for long exposures and helps avoid overexposure issues.

ZWO ASI585MM-P Overview
8.3MP Color Sensor
The ASI585MM-P features an 11.2 x 6.3mm back-illuminated Sony sensor with a resolution of 3840 x 2160. The 2.9µ pixels accommodate a full well capacity of 38.7ke. The sensor boasts a quantum efficiency of 91%.
USB 3.0 & 512M DDR3 Memory
The camera is equipped with a USB 3.0 transmission interface and a built-in 512MB 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.
Two-Stage TEC Cooling
The sensor can be cooled to 95°F below the ambient temperature, holding down dark current noise.
No Amp Glow
Using zero-glow amp circuitry, the ASI585MM-P eliminates amp glow—a weak infrared light source often created by traditional CMOS sensors, sometimes seen in the corners of uncalibrated images. You won't have to worry about it, even during high-gain, long-exposure imaging.

ZWO ASI585MM-P Reviews
Excellent for Solar H-alpha
By Curtis
Rated 5 out of 5

I use this camera with my Lunt40 to live stream the Sun in H-alpha. Its small pixel size and 4K resolution, make it fantastic for this. I don't use it for DSO, I use a OSC ASI585MC Pro for that. But my experience with the color version of this camera made me sure it would be fantastic for Solar, and I wasn't disappointed. See the two colorized sun images, one of them inverted. It's a fantastic camera.

Have taken many images at different targets. I like its QE at the near infrared.
