QHY Sony Monochrome Cooled CCD Cameras

QE ExView Sony Sensoren

The QHY22 and QHY23 cameras use Sony's high-sensitivity EXview HAD CCD II sensors, ICX674, ICX694 and ICX814, respectively. Although not back-lluminated, the QE of these sensors is very close to the performance of back-illuminated sensors (nearly 80%) and also exhibit very low dark current 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.

QHY 21, 22, 23

The read noise of these cameras is also a highlight of their 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. These Sony sensors all have relatively small pixels for high resolution.

The pixel sizes of the sensors used in the QHY 22, 23 cameras are relatively small. Compared with larger pixel CCDs, this allows for higher detail using smaller telescopes. You can get a stunning view with a shorter focal length optical system.

The QHY 22 and 23 offer full moisture control, including an air-proof CCD chamber with desiccant plug socket and a CCD chamber optical window heater. Mechanically, the QHY 22 and 23 are solidly built and include USB/Power cable support. With this support, the USB and power cable will stay solidly affixed to the camera assuring a constant electrical contact.

All models have a built-in USB 2.0 HUB and dual USB to RS232 converter. External trigger in and out is provided at the back of the camera. A guiding camera, mount and electric focuser can all connect directly to the camera instead of separate connections to the computer. Only one USB cable is required control the whole system for capturing an image. The power socket has a threaded locking collar and the 3-pin aviation socket RS232 port make the system stable and solid. A 4-pin color wheel port is also available to connect a QHY color filter wheel.
