The Philips SPC900NC/00 is regarded as one of the best web cameras used in astrophotography, particularly in planetary imaging. By attaching the web camera to a telescope using a special type of adapter, it is now possible for amateur astronomers to take high-quality photos of planets. With some circuit modification, this camera may also be used as a guide camera for autoguiding purposes. Its main imaging sensor is a CCD, roughly 10 times more sensitive than the CMOS sensor used in other web cameras. Since not many cameras are equipped with CCDs (there’s only quite a few actually), it has earned a reputation of being one of the most sought-after web cameras in the astronomical community today.
