The QHYCCD QHY10 is an APS size cooled one shot CCD camera with Sony's ICX494AQA Sensor. It has 10.2 mega pixel and the pixel size is 6.05 x 6.05um.
Beside the very low thermal noise of Sony's SuperHAD technology, this sensor has a high fullwell feature. Even in a 6.05um square pixel, it has 45ke fullwell. Which is almost double than the ICX413 with 7.8um square pixel and almost double than the color 8300 sensors with 5.4um square pixel. The big fullwell gives the advantage of higher dynamic range. It brings better colors and smaller star point. You can make a longer exposure time without signal saturated.
It is a real cooled CCD camera that uses two stage TEC. It can get -40C delta T below ambient. Combine with QHYCCD cooling technology and Sony SuperHAD technology QHY10 give you a clean and low noise image even in a very long exposure. It comes with a clip for USB and power cables. It makes the connection solid and avoids the contact/loss conditions.
