The QHY183C camera uses the back-illuminated Exmor R Sony IMX183 20MP sensor for higher sensitivity and quantum efficiency than traditional front-illuminated designs. This color sensor has an active array of 5544 x 3694 pixels that are 2.4um in size, with readout noise as low as one (1) electron! This CMOS astrophotography camera is capable of 4K HD (25 FPS) video output and full resolution real time output at 15 frames per second.
The QHY183C camera has a two-stage TEC cooling and temperature regulation system that can cool your camera down to as low as -40C below ambient. QHY has also incorporated anti-dew technology into the QHY183. The CMOS chamber is fully sealed, and includes a silicon gel tube socket as well as a heater to help keep both your sensor and the sensor window dry and fog-free, even on humid nights.
A built-in 128MB DDRII image buffer provides a safeguard in this CMOS astrophotography camera against unexpected drops in data transmission. A frame buffer avoids lost frames during USB transfer by storing image data in the camera itself until it can be safely transmitted. Buffering will also make sure your video runs more smoothly when using a slower computer that cannot always handle high speed data well.
All semiconductors produce a small amount of light when powered up, causing brighter spots in the corners of the sensor where the high gain amplifiers are housed. Amplifier glow is most noticeable during long exposures taken with CMOS astrophotography cameras. The QHY183C camera has an anti-amp light control circuit to reduce amplifier glow significantly.
