The QHY294M Pro camera is capable of locking and unlocking the on-chip binning to provide two readout modes. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe first mode reads the sensor “locked” mode to produce 11.6mp images with 4.63um pixel size and 14 bits per pixel. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe second read mode unlocks the binning to produce 46.8mp images with 2.315um pixel size at 12 bits per pixel.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBSI: \u003c\/strong\u003eOne benefit of the back-illuminated CMOS structure is improved full well capacity. In the back- illuminated sensor the light is allowed to enter the photosensitive surface from the reverse side. In this case the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency the more efficient the sensor is at converting photons to electrons and hence the more sensitive the sensor is to capturing an image of something dim.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTRUE RAW Data: \u003c\/strong\u003eIn the DSLR implementation there is a RAW image output, but typically it is not completely RAW.  Some evidence of noise reduction and hot pixel removal is still visible on close inspection.  This can have a negative effect on the image for astronomy such as the “star eater” effect. \u003c\/p\u003e\n\u003cp\u003eHowever,  QHY offers TRUE RAW IMAGE OUTPUT and produces an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCooling: \u003c\/strong\u003eIn addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise. The optic window has built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnti-Dew Technology: \u003c\/strong\u003eBased on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions. The optic window has built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew and the sensor itself is kept dry with our silicon gel tube socket design for control of humidity within the sensor
