Gain in imagen astronomical

WebUnderstanding an astronomical CCD image. An astronomical image like the one shown below is essentially a two-dimensional array of values. In an ideal world, the value of each pixel (a pixel being one element of the array) would be directly proportional to the amount of light that fell on the pixel during the time the camera's shutter was open. WebJun 29, 2024 · Gain is equal to amplification; in CMOS technology it means electronic image amplification. The gain is directly comparable to setting the ISO in a DSLR. Here there is the standard choice starting at ISO 100 up to ISO 6400 and with modern cameras far beyond. The gain setting is one of the most important parameters for CMOS sensors.
