In a basic sense, this means that no matter how many frames you take to increase your signal-to-noise ratio for a cleaner image, you will always run into a wall of noise when you stretch your image to bring out deep shadows. But with QHY\u2019s new CMOS camera, this troublesome wall of noise is nonexistent.<\/p>\n<p>The QHY 410C is a one-shot color camera that utilizes the back-illuminated Sony IMX410 CMOS chip found in high-end cameras like the Nikon Z6 and the Sony A7 III. But the 410C has taken the full-frame (35 millimeter) 24-megapixel chip and mounted it in a camera with regulated cooling and zero amplifier glow, helping drive the noise to such a low level.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Move aside CCDs.
