QHY 247C Cooled Color Astronomy Camera
The QHY247C is a cooled USB 3.0 color imaging camera with a 24 MP CMOS sensor. The QHY247C sports the Sony IMX193; an APS-C color sensor with a 6024 x 4024 array of effective 3.91 µm square pixels. This is the same sensor that is used in the Nikon D5300 and D5500 camera. It has very low readout and thermal noise, with 2.7e at lowest gain and 1.0e at high gain. The IMX193 sensor is housed in a sealed chamber that is heated to prevent dew from building up on either the sensor or window.
The QHY247C comes with a two-stage TEC cooling and temperature regulation system that can cool your camera down to as low as -40ºC below ambient. QHY has also incorporated anti-dew technology into the QHY247. 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, even on damp nights.
The QHY247C allows for true raw image output! When you get the original signal to work with, you have maximum flexibility in the image processing stage of the process. Also, a built-in 128MB DDRII image buffer provides a safeguard 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.
