QHY128C Cooled CMOS Camera. Full frame sensor (36 x 24mm) with a 43mm diagonal and 5.97 microns pixel size. Full resolution output is 5fps and 74ke-Full Well Capacity

The QHY128C cooled CMOS camera is one of the top performing cameras in the COLDMOS line. The Sony Exmor IMX128 sensor is used in the Nikon D600 DSLR. In the QHY128C this sensor is implemented specifically for astronomical use with custom thermal noise reduction technology. With low (1e- to 4e-) read noise, 5.97um pixels, 74ke- full well capacity and 14-bit A/D, the camera has a dynamic range of more than 14 stops.

Compare with the QHY367C which is a similar full frame camera but with 4.88um x 4.88um pixels.

Many cameras claim to output RAW image files, but there is often some internal processing still performed on the image. This can have a negative effect on the image for astronomy such as the “star eater” effect. The QHY128C outputs TRUE RAW data, preserving the original data for maximum compatibility with astronomical imaging processing programs and other scientific imaging applications.

In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise in the QHY128C. As a result the dark current of this camera is a remarkable 0.0006e-/p/s at -15C, the lowest dark current of any camera in the COLDMOS line.

The optical window has high quality AR+AR multi-layer coatings. In addition the sensor surface is AR coated, all of which significantly reduces halos around bright stars. IR blocking is not present, so that the cameras can be used with maximum sensitivity to H-alpha and near IR when desired, or a simple IR blocking filter (L filter) can be attached for typical RGB imaging with IR cut.

With the QHYCCD anti-amp glow system, the QHY128C exhibits zero amplifier glow, even in long exposures. This makes long exposures of DSOs possible and easier to process. There are only a few CMOS cameras that can achieve zero amplifier glow results. The QHY128C is one…..
