Details
The QHY50GX uses On Semiconductor (Kodak) KAF−50100 Image Sensor, a high performance, 50- megapixel CCD. Based on the TRUESENSE 6.0 micron Full Frame CCD Platform, the sensor features ultra-high resolution, broad dynamic range, and a four-output architecture. A lateral overflow drain suppresses image blooming, while an integrated Pulse Flush Gate clears residual charge on the sensor with a single electrical pulse. A Fast Dump Gate can be used to selectively remove a line of charge to facilitate partial image readout.
The sensor also utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode. The full imaging array is read out of four outputs, each of which is driven by a low impedance two stage source follower that provides a high conversion gain. This combination enables low noise at a net readout rate of 12 MHz (3 MHz per output).

Astrophotography camera for deep-sky: what to choose
Choosing from various astrophotography camera for the deep-sky may seem complicated. In this article, through a series of practical examples, we will see how to choose astrophotography camera to record also the weakest details of galaxies, nebulae and star clusters through with long exposures (these camera are different from those used for planetary and lunar photography that record short videos and which we will discuss in a later article). Astrophotography camera for the deep-sky are almost always cooled, ie have a system with Peltier cells which cools and stabilizes the sensor at a low temperature in order to reduce the noise of the image and therefore improve its quality.
