The QHY 168C Pro is a cooled colour camera with large pixels and low noise.

It contains the Sony IMX 071, which is an APS-C sensor, the same sensor that is used in the Nikon D5100 DSLR camera. The pixels measure 4.8µm, making this camera ideal for medium-long focal length Scopes but also camera lenses and short refractors that may suffer from elongated stars on the borders.

 

Large pixels can mask minor aberrations of the telescope that are generally visible in cameras with small pixels (2-3 µm). Unlike DSLR cameras, the QHY168C Pro offers true RAW Image output that only records the signal without artefacts.

Standard DSLR's have the RAW output option but the file is altered with noise reduction and hot pixel removal, undermining the maximum post processing capabilities and final quality of the image.

This camera has a two-stage TEC cooling system that brings the temperature of the sensor 35C° to 40C° below ambient for low noise imaging, even in warm climates. The dark current at -15°C is only 0.0007 electron/pixels.

In addition to thermoelectric cooling, QHYCCD employs a unique thermal noise control technology to reduce CMOS sensor noise to a very low value without affecting the integrity of the raw image.

The QHYCCD proprietary technology produces a much better noise reduction than any other astronomy camera in the market. QHYCCD has more than 10 years of experience designing cooled cameras.

The QHY 168C employs a full anti-dew technology for both CCD sensor cover glass and the sensor chamber optical window.

The 128MB DDR II memory buffer facilitates the download of images to the computer, especially when USB traffic is high, the writing speed of your computer is slow or occupied in other processes.

In order to avoid halos around bright stars, the QHY168C has an AR coated optical window on both sides rather than the common IR/UV cut window.

For a better RGB colour balance, it is recommended to use a UV/IR cut filter. Every QHY 168C Pro camera is carefully calibrated with a high-precision axis measurement device.

The orthogonal placement of the sensor in the camera body is guaranteed to be flat to the image plane with a precision higher than +/-20µm across the sensor, from edge to edge, so there is no need to adjust the camera tilt.

This is an enormous advantage especially in fast scopes such as F/2.8-F/4 astrographs which are very sensitive to tilted sensors. The QHY 168C has zero amplifier glow no matter how long the exposure is.
