The QHY 178C is a cooled colour camera that contains the Sony IMX178 colour back-illuminated sensor. It has 6 Megapixels with a diagonal of 8.9mm. The pixels have a size of 2.4 µm. This camera is ideal for serious planetary imaging and entry-level deep sky photography.
This camera has a two-stage TEC cooling system that brings the temperature of the sensor 40C° below ambient for low noise imaging, even in warm climates. 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 178C 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 with other processes.
The optical window has an IR/UV cut coating which is necessary for a correct colour balance. The QHY 178C has zero amplifier glow no matter how long the exposure is.
