Description

The QHY23 camera uses Sony’s ICX814 high-sensitivity EXview HAD CCD II. This sensor has very high QE (close to 80%) and very low thermal noise.  QHYCCD’s dual stage TE cooling technology reduce the sensor temperature up to -45C below ambient for exceptionally low dark current.  Compared to competing models, the QHY cameras achieve -10C to -15C extra cooling, resulting in very low noise and uniform background even during the hot summer months. 
 
The read noise of this camera is also a highlight of its performance.  Typical read noise is around 5 electrons. Low read noise is very important when you want to capture faint deep sky objects or when using narrowband filters.  Less read noise also means you can get a better image when you stack multiple frames.  This Sony sensor has relatively small pixels for high resolution. Using a suitable OTA results in outstanding detail as the sample images at the bottom of this page show.
 
The QHY23 offers full moisture control, including an air-proof CCD chamber with silicon gel tube socket and a CCD chamber optical window heater.  Mechanically the QHY23 is solidly built and includes a USB/Power cable support.  With this support, the USB and power cable will stay solidly affixed to the camera assuring a constant electrical contact.
