— 24MP APS-C Cooled Color CMOS Camera
Ultra High Performance
QHY247C has a APC-S 24mega pixels, 14bit CMOS sensor IMX193. This sensor is also used in the D5300 and D5500 camera. It has 2.7e low readout noise at lowest gain and 2.2e low readout noise at unity gain(system gain = 1e/adu), and 1.0e at high gain. QHY247C is camera with LOWEST readout noise and thermal noise in the QHY165C/168C/247C/367C production line.
True RAW Imag Output
QHY247C has the same CMOS sensor like D5300/D5500.But D5300 only offer 13bit and both D5300 and D5500 is not really RAW output even it is “RAW” format. You will find the de-noise sign on the raw images from the hot pixel styles in the DSLR dark frames. While the QHY247C offers the TRUE RAW IMAGE OUTPUT and it gives original signal and keep the max flexibility of astronomy image process.
Unique Thermal Noise Reduction Technology
Besides the 2-stage TEC, QHYCCD has an unique thermal noise control technology to get the cmos sensor very low thermal noise and make whole 165/168/247/367 product line has much better thermal noise performance than competitors.
Zero Amplifier Glow
QHY247C has a rarely capability of zero amplifier glow no matter how long the exposure time is.
Advanced AR Coating on CMOS sensor
IMX193 sensor has a AR coating cmos sensor glass. It also has the AR coating micro-lens array. This design have great help to reduce the halo arround the bright stars.
