The QHY550 has the 2/3-inch SONY 5.0mega pixel IMX250 Global shutter CMOS sensor. Besides the monochrome version it has a special polarized version. QHY550 has a built-in two stage TEC cooler. It can cool the sensor to -35C below ambient. This can reduce the dark current of IMX250 significantly--greatly improving the dark signal detect performance. This is especially true for detecting the tiny differences of the polarized light which is necessary for astronomy, life science and optical lab.
