QHY 168C APS-C Cooled CMOS Astro Imaging Camera - Colour
Cooled APS-C-sized astrophotography camera, suited for deep-space imaging.
The performance and specifications of this camera are similar to the QHY165C, but the analogue data is recorded with a 14-bit (16384 shades) resolution, higher than the QHY165C's 12-bit (4096 shade) resolution.
The QHY168C is a popular APS-C format cooled color camera. The SONY Exmor IMX071 sensor has 4.8µm pixels and 2.3e- to 3.2e- read noise. This sensor was used in the Nikon D5100 DSLR camera. With read noise this low, it is easier to detect a dim target against of the background noise.
True RAW 14-bit
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 QHY168C outputs TRUE RAW data, preserving the original data for maximum compatibility with astronomical imaging processing programs and other scientific imaging applications.
Noise Reduction Technology
In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise in the QHY168C. As a result the dark current of this camera is a remarkable 0.0007e-/p/s at -15C.
Anti-reflection coatings and NIR sensitivity
The optic window is coated on both sides with anti-reflection coatings. IR light is not excluded meaning that the cameras are highly sensitive to H-alpha and near IR. Alternatively, a simple IR blocking filter (L filter) can be attached for typical RGB imaging.
The optic window has built-in dew heater and the sensor chamber is protected from internal humidity condensation.
128MB DDR Buffer
The QHY168C has a 128MB DDRII buffer. This can store more than one 72MB frame. Buffering inside the camera lowers the risk of data loss during downloading via USB 2.0 or to slow computers.
