Camera
A camera is used for two main tasks. The main imagening camera and as a guide camera.
The Main imagening camera is usually ether a CCD or a CMOS type sensor.
The CCD has always been and is still by reputation the more sensetive of two. It is however also the most expensive.
And the CMOS is catching up. Partly because it is the sensor used in pretty much all imagening devices today. From mobile cameras to DSLR cameras. This boosts the development and is pressing the price.
