The QHY367C is the top performing full frame camera in COLDMOS Series. The Sony Exmor IMX094 CMOS sensor is also found in the Nikon D800/810 DSLR cameras. This sensor is implemented in the QHY367C specifically for astronomical use with QHYCCD thermal noise reduction technology. With read noise as low as 2.4e-, full well capacity of 56ke-, and 14-bit A/D, the camera has a dynamic range of more than 14 stops.
Many cameras claim to output RAW image files, but there is often still some internal processing performed on the image. This can have a negative effect on the image for astronomy such as the "star eater" effect. The QHY367C 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 QHY367C. As a result the dark current of this camera is a remarkable 0.0015e-/p/s at -15C.
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 technology, the QHY367C 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 QHY367C is one.
The QHY367C benefits from more than a decade of cooled camera design experience. QHYCCD has implemented full dew control solutions. The optical window has a built-in dew heater and the CMOS chamber is protected from internal humidity condensation.
QHYCCD offers a variety of mechanical adapters for the QHY367C allowing it to fit a broad range of accessories, including the QHYCCD OAG, 0.5mm-27.5mm flexible back focus adjust spacer, 2-inch T-ring, IR filter holder and more. QHYCCD has a combination table which can be found on specification page.
The QHY367C has a 128MB DDRII buffer which is greater than one full frame (72MB per frame) and is ideal for buffering the image in the camera. It helps tremendously with slower computers and also USB2.0 connections where it improves the data transfer stability and flow control.
