The QHY367C uses the IMX094 full frame, 35mm format, 36 Megapixel, 14-bit CMOS sensor. This sensor is also used in the Nikon D810A camera. It has 3.2e- read noise at lowest gain, 2.4e- read noise at unity gain (system gain = 1e-/ADU), and high dynamic range of more than 14 stops.

Anti-Dew Technology
QHYCCD has more than 10 years of experience designing cooled cameras. The QHY367C receives the benefit of that decade of design work by featuring full anti-dew technology for both CCD sensor cover glass and the sensor chamber optical window. The QHY367C has an electric heating board for the chamber window to 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 chamber.
AR coated CMOS Sensor Surface
The IMX094 sensor used in the QHY367C has the multi-layer AR coated. This coating will help to reduce the halo around the bright stars. Normally speaking the uncoated sensor surface only about T = 92% ratio (Reflective is about 8%) while the AR coated surface can get up to 98% to 99%. (Reflective ratio is only 1% to 2%).
AR+AR Optical Window
In order to avoid halos around bright stars the QHY367C has a AR+AR coated optical window rather than the common IR cut window for Single-Shot Color cameras. This permits full access to the red wavelength of H-alpha and SII without attenuation by the window coating. For RGB color balance, without passing the near IR wavelengths above 700nm, a separate removable 2-inch UV/IR filter with the desirable band pass characteristics is placed in a custom filter holder in front of the camera.
