Brand Name:ZWO Origin:CN(Origin) Model Number:294MMP ASI294MM Pro is the black and white version of ZWO's bestselling color deepsky camera ASI294MC Pro, 4/3 format, 14bit ADC, 4.63um large pixel equipped with 66ke full charge. The camera resolution is 4144x2822, and the total pixel is 1170. With very high QE and ultralow read noise, it is the best choice for current smallformat black and white astronomical cameras 14bit ADC and 13 bit dynamic range ASI294MM Pro has a 14bit ADC digitaltoanalog conversion, which can reach a dynamic range of 13 bits, which is higher than the dynamic range of ASI1600MM Pro and is very suitable for deep space photography. Backilluminated CMOS The traditional CMOS sensor is a frontilluminated sensor. There is a metal wiring layer on the photodiode, and light will be blocked or reflected when passing through the wiring layer, causing the photodiode to only absorb 70Percent of the light or even less; The backilluminated sensor optimizes the structure. The diode is placed in front of the metal wiring layer, and the light is directed from the back, the absorption rate is higher, and the sensitivity and imaging quality have also been greatly improved. Camera curve: high full well, high dynamic range, low read noise ASI294MM Pro has 66387e full trap charge, which is among the best among all ASI deep space cameras. The super high full well gives 13 stops of high dynamic range, even if there are bright stars in the field of view, it is not easy to overexpose when shooting, and the color gradation of the image will be richer. The readout noise of the camera is very low, with a minimum of 1.2 electrons. The unique HCG mode can effectively reduce read noise even at high gains. When the gain is 120, the read noise will drop significantly and the dynamic range will also rise. ;
