The ZWO ASI 294MM PRO is a highly versatile monochrome cooled camera with a large sensor which is ideal for wide field astrophotography. This new mono version of the ASI294 features the Sony IMX492 back-illuminated sensor which 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.


ZWO ASI294MM Pro CMOS cooled deep sky camera specifications

 

The ASI294MM Pro has an outstanding QE value with a peak of 90%, ultra-low read noise of 1.2e- and full well capacity of 66,387e-. The camera has a 14-bit ADC with a high dynamic range of 13 stops, higher than the popular ASI1600MM Pro.

When the gain value is set to 120, HCG high gain mode is turned on. In this mode the readout noise will be largely decreased (as low as 1.2e), and the dynamic range is basically unchanged.

Unlocked Bin1: 12bit ADC, 2.3um pixel size, 47 megapixels, 8288*5644 resolution, 14k full well capacity.

The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 16.3fps at full resolution (11.7 Megapixel). 

The USB 2.0 Hub allows to connect 2 USB controlled accessories such as a filter wheel, a guiding camera or an electronic focuser, reducing the amount of cables that run directly from your computer.

The 2 stages TEC cooling system allows a ΔT of 35°C-40°C below air temperature. The cooling system requires an external power supply of 12V at 3-5A with a 2.1×5.5mm connector (positive tip). The ASI 294MM can be powered with a standard lead battery or a DC source between 9-15V.
