Large well depth capacity, low read-out noise and high dynamic range!

*Contrary to the image extracted from ZWO above, the sensor is a Sony IMX294.

The ZWO ASI294MM Pro is a monochrome astronomy camera equipped with a 4/3" Sony IMX492 CMOS sensor, featuring a 23.2mm diagonal and 11.7-megapixel resolution (4144 x 2822). It offers 4.63µm pixel size and operates with a rolling shutter, providing an exposure range from 32 microseconds to 2000 seconds.It is the mono version of ASI294MC Pro, one of the top selling cameras from ZWO. 

Not only does it have a very high QE value with a peak at about 90%, but feature an ultra-low readout noise of 1.2e. If you are seeking for a small-format mono camera for astrophotography, then ASI294MM Pro going to be your ideal choice. 

Camera Performance 

The full well capacity of 66387e of ASI294MM Pro is near the top of all ASI DSO cameras. It ensures a very high dynamic range up to 13stops that will greatly reduce overexposure probability and help gain richer color gradation.

The ZWO ASI294MM Pro incorporates two-stage TEC cooling, capable of reducing the sensor's temperature by 35°C to 40°C below ambient, significantly reducing dark current and noise for long-exposure astrophotography. It includes a USB 3.0 interface for fast data transfer and features a 256MB DDR3 memory buffer to ensure stable operation.

The ASI294MM Pro is a versatile and high-performing option for deep-sky and planetary imaging.
