The QHY27, QHY28 and QHY29 cameras use the latest TRUESENSE interline CCD sensors. These sensors have electronic shutters for very short exposure times. The QHY27 with KAI-16050 CCD is APS-H format. The QHY28 with KAI-16070 CCD and QHY29 with KAI-29050 CCD are full frame (35mm format) CCDs. QHYCCD's anti-dew technology and 2-stage TE cooling enable cooling of the sensor to -45C below ambient. This reduces the dark current to less than 0.05e- at typical operating temperatures.
The KAI−16050 Image Sensor is a 16−megapixel CCD in an APS−H optical format. Based on the TRUESENSE 5.5 micron Interline Transfer CCD Platform, the sensor features broad dynamic range, excellent imaging performance, and a flexible readout architecture. A vertical overflow drain structure suppresses image blooming and enables electronic shuttering for precise exposure control.
The KAI−16070 Image Sensor is a 16−megapixel CCD in a 35 mm optical format. Based on the TRUESENSE 7.4 micron Interline Transfer CCD Platform, the sensor provides very high smear rejection and up to 82 dB linear dynamic range through the use of a unique dual−gain amplifier. A vertical overflow drain structure suppresses image blooming and enables electronic shuttering for precise exposure control.
The KAI−29050 Image Sensor is a 29 Megapixel CCD in a 35 mm optical format. Based on the TRUESENSE 5.5 micron Interline Transfer CCD Platform, the sensor features broad dynamic range, excellent imaging performance, and a flexible readout architecture. A vertical overflow drain structure suppresses image blooming and enables electronic shuttering for precise exposure control.
All three 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.
