The QSI 520c camera employs a 2 megapixel Kodak interline transfer CCD image sensor with microlens technology. Integral Bayer RGB color filer mask allows Single-Shot color imaging. The high quantum efficiency, wide dynamic range and low noise performance make the 520c ideally suited to a broad range of demanding astronomical, scientific and industrial imaging applications.
All 520c models utilize the electronic shutter built into the KAI-2020CM CCD image sensor to control exposures. Shutter timing is very precise and can range from as short as 100 microseconds up to 240 minutes.
The Model 520cs camera incorporates the optional internal mechanical shutter in the 'mid-size' camera body configuration. When operating with an interline transfer CCD, a mechanical shutter is not used to actually make the exposure. This is still the responsibility of the electronic shutter. The mechanical shutter is employed to cover the CCD and simplify the creation of Dark and Bias frames for subsequent image processing.
Integrated Guider Port
The Model 520csg camera has the internal mechanical shutter like the 520cs, plus it adds an Integrated Guider Port. This allows guiding using the light from your main telescope while picking off the light from the guide star

Single-Shot Color Imaging
Single-Shot color imaging is made possible by overlaying the pixels on the CCD with an alternating red, green and blue color filter matrix at the time of manufacture. This is the same technique used by the vast majority of color video and still cameras to create color images. Single-shot color imaging eliminates the need to take a sequence of images through multiple color filters and is essential for applications with moving subjects.
