The ASI294MM Pro is the monochrome version of the ASI294MC Pro, one of ZWO's most popular astronomy cameras. This monochrome, cooled camera features a 4/3" 11.7MP Sony IMX492 sensor capable of true 4K resolution, ultra-low 1.2e read noise, and an exceptional 90% quantum efficiency. Integrated two-stage TEC cooling reduces sensor temperature to 30-40 degrees Celsius below ambient temperature for low-noise deep-sky imaging. The sensor is natively binned 2x2 to give 4.63 µm pixels, ideal for long focal length telescopes, but can be unbinned to give small 2.3 µm pixels for wide focal length scopes such as refractors.
