ZWO ASI294MM [MONO]
ZWO ASI294MM [MONO] is a special order item. Contact us for more info.
The ZWO ASI 294MM PRO is a highly versatile monochrome camera with 4/3" sensor. This camera feature 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.

The ASI294MM 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.
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.

Bin2 (The default mode): 14bit ADC, 4.6um pixel size, 11.7 megapixels, 4144*2822 resolution, 66k full well capacity.

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) and 19fps (12bit, high-speed mode).
