The QHY174M has dual stage TE cooling to -45C below ambient with full anti-moisture control including heated optical window and removable silicon tube for the sensor chamber. The camera has our 4-pin QHYCFW2 filter wheel control port and a 6-pin autoguider port. The QHY174 also has an anti-amp glow function. It can reduce the IMX174 sensor's amplifier glow significantly in long exposures.
The IMX174 sensor has a global shutter and is capable of high frame rates, both ideal features for a time-domain imaging camera. In 2014 Sony introduced this device which featured a new technology called Pregius ?, redefining the global shutter CMOS imaging category and providing the best of both worlds with fast frame rate and CCD-like imaging performance. The technology offers lower dark noise, which enables higher gains without compromising image quality, as well as higher quantum efficiency. The global shutter also eliminates pixelization caused by atmospheric agitation when imaging the Planets and Moon at high frame rates.
